How to Get Relief from Technology Stress

Technology has certainly simplified our lives but it has its vices too! The saying that, “science is a good master but a bad servant” holds completely true in the case of technology. As per a new report, working women in U.K think that technology has made their lives more hectic and complicated. The constant buzzing and beeping of cell phones, music systems, and other gadgets has certainly increased the level of stress and anxiety in our lives.

We cannot escape from using technological gadgets but we can certainly find out ways for dealing with it. Here are some simple tips which can relieve you from the stress caused by technology:
All of us operate our computers on a regular basis, but how many of us actually know about the computer operations in detail? If you know more about the features of your computer, then you will be able to know how to operate it efficiently and what t do if it stops working. Many computer problems can be handled efficiently if we know more about it!
Most of us tend to ignore the error messages that appear on our computer screen. But this should not be done. Whenever you see some error message popping up on your computer screen, just research about it! Try to know what is this and why does it occur. After learning about it, you may take concrete steps to solve the problem yourself!
Is your computer hanging a lot? Is it taking more time than normal to open up an icon? Instead of getting irritated when you computer runs slow, take out time and defragment your device. Many a times, our computer runs slow because we don’t arrange files properly. Hence, you should arrange your files properly (by name or work) and delete the ones that are no longer in use. Manage all the tools efficiently so that you are able to deal with every sort of computer problem.
What about taking a break from your regular computer work? Many times, we need a break from our regular work to get reenergized or revitalized. For example, you may use the Zen art of using computers conveniently. Taking short breaks from programming, writing or something else- will certainly help you to feel more relaxed and stress-free.
Don’t overload your system. Know the limits of your Floppy disks and drivers so that you don’t overload them! Learn how to install an uninstall drivers or software’s- it will surely help you out!

Well, above are some of the ways in which you can keep yourself fee from technology stress! Have a happy and healthy life!

Air Cars

Air Cars are the newest addition to the range of cars in an attempt to prevent/reduce the exorbitant amount of pollution present in the atmosphere. Although, the air car sounds like a very new idea but it has actually been around for quite sometime now. The compressed Air car has been termed as the “zero pollution” car and is thought to be a realistic attempt to solve all the environmental problems.

The working of the air car is not very complicated and it works very easily. Basically, compressed air is used to power the vehicle and it is emitted out as cold air. Compressed air is forced into the converter pushing the pistons as a conventional petro converter would push pistons using tiny explosions. This engine is certainly going to save money for all the people and would reduce the reliance on fuels in all the countries. It is certainly a wonderful idea for a “greener and cleaner earth”.

The Air car can travel along at top speeds of 35 mph for some 60 miles on a tank of compressed air, a sufficient distance for 80% of consumers to commute to work and back and complete daily chores. This makes the car very suitable for all the environmental activists. Refilling the car will take place at adapted petrol stations for administering compressed air. In two or three minutes, and at a cost of approximately 1.5 Euros, the car will be ready to go another 200-300 kilometers.

In fact, you would be surprised to know that Zero Pollution Motors, the U.S. licensee of Luxembourg-based Motor Development International, has an air car scheduled for production in the U.S. in late 2009 or early 2010. At the speeds of 35 mph, this particular car will just use only small amounts of fuel for heating the air inside a heating chamber and thereby allowing the car to get to an estimated top speed of 96 mph.

In spite of the above features, the air car is still not ready to be used in United States, probably due to many safety reasons. But there is a report that the air car is going to be in the country by 2010. If the air car is going to make an appearance in 2010, then it will come with a price tag of $18,000. Although, the air car might just have 75 horsepower but has the ability to drive around 1000 miles before you will need to refill the air.

So, it is certainly good news for those who have been waiting for this amazing air car! I hope that all of you will enjoy sitting in the car and will have a great time riding in the air!

Biometric Systems is Useful for Authentication or not?

Biometric refers to the human specialties like finger prints, iris recognition, DNA sequence, face recognition etc. in fact the biometric is used for identification of the person. You must have heard about the authentication. The question arises that what is authentication? I must say that authentication means verification and without the verification you cannot precede further. Hence if you want to succeed in using some valuable thing which is protected by the biometric system then you will have to pass the authentication test.

The question arises that to what limit is the biometric system applicable? The answer is to a certain limit but this limit is quiet more than any other mode of authentication. Just think when your finger print is the code to open any door. Can any one other than you open it? No, certainly not. No one else will be able to open the door as it requires you’re your finger prints which is unique for every other person. However, you must have seen in some of the Hollywood movies that the villain steels the finger prints from the hero and finally is able to open the door. You can understand that how much job he had to do.

Now think of the Iris recognition. Do you know how it works? Wait I will tell you. Actually the retina of every person is unique and you can differentiate between one person and the other with the help of the retina. There are many iris recognition systems where you can register your retina and then your retina will be the password to the system. Once you are able to pass such biometric system comprising of the iris, you will be able to access the data inside it.

These biometric systems are not only used to lock the doors. They are also used to lock the computer files. On the higher level such information becomes useful and its seepage to any other person can cause the loss of billions of dollars. Hence you will definitely like to safeguard your files from the other users. For doing that you will definitely like to use the best authentication services and today the biometric systems are the best for such a high level of authentication.

Keeping all these things in mind I do feel that the biometric systems are really the best in today market. And one of the other biometric systems which are DNA has really made this system more secure than before. The DNA sequence of any person is too unique and can be used fro authentication.

I must say that the biometric systems are the best way of authenticating any security features and you should definitely use this one as it is the safest.

Wireless Electricity

Ever tried to imagine life without wires? Ever thought of having wireless electricity in your home? Well, if you have, then you are surely going to have great time. If everything goes according to the plan, then you may have electricity in your home and that too without wire! Sounds too good to be true! But, it is a reality in itself and soon you will get rid of all the wires/cables in your home.

Basically, wireless energy transfer process takes place in an electrical system where electrical energy gets transmitted from a power source to an electrical load, without the presence of interconnecting wires in an electrical grid. As you can see, there are various components needed for a wireless energy transfer. The size of the components used can be determined by using the Rayleigh Criterion or Diffraction limit used in standard RF (Radio Frequency) antenna design.

The experts in the industry believe that in near future, the power supply to your home will not depend on the electricity department but on you! I know that it sounds very unusual but it is true! You may not even be required to pay the mandatory bill amount when you are spending a vacation outside or when you are shutting off the house. It may be in the next 20 or 30 years but it is certainly going to be there!

Well nowadays, the electricity that we use is hazardous for the environment because it releases large amount of Carbon dioxide in the air. Due to the rising concern about environmental problems, it has been postulated that the electricity in future is going to be clean and green! Currently, the electricity is produced mostly by consuming fuels that are on the verge of being extinct. So, you can see that the future of wireless electricity is certainly bright and brilliant.

Apart from wireless electricity, a lot many things of daily use are going to be electrified as well. You may have electric shoes, electric combs, watches, glasses, and even electrical clothes. Now, don’t you think that its’ fantastic! And if you are still not able to believe whatever I am saying, then kindly visit he futuristic shops at Akihabara in Japan for having a glimpse of the future. It will definitely bewilder and excite you!

Well, above are some of the benefits of having wireless electricity. Although the experiments and processes are being carried out but nothing has been finalized till yet. However, the future certainly seems bright and interesting! So, think positive and hope for the best!

Tips to Choose Electrical Appliances

People are nowadays switching to electrical appliances as they provide the maximum safety and the benefit of doing fast work at homes even in the hectic schedule. These electrical are intelligent enough to automatically shut down after their work so that they can save the power. They are more energy saving as well as cost saving, portable too carry from one room to another. They completely eradicate the concept of fire so there are no chances of burnt while cooking or doing something else work.

There are various tips to consider while choosing electrical appliances.
There are traditional stores both online and offline where you can easily find the electrical appliances. You can buy the vacuum cleaners, a dishwasher, kettle, etc. thus you have a huge range of manufacturers from which to choose, but also an enormous collection of models, colors, speeds, power specifications and so on.
The best way is to go to your nearest retail center and pick up according to your choice. Another best possible way is to take the help of in-store sales person.
Buying from the stores is not as popular as it is from buying from the Internet shopping. The high street stores have the different prices and it is really less to buy from the online stores. The rates that you will find here are affordable.
There are bit problems about online stores that you have to click from one website to another, write down the information before making the choice. There is basically no one to tell you about the proper functioning, their specifications, etc.
Try to buy from the comparison site that compares and reviews a number for you. The site itself checks up on the specifications and compares what you get with what you pay, and then you can make your mind up yourself on which you want. Such comparison sites are becoming increasingly popular with online shoppers, since they can compare products sold across a wide range of online stores, and even auction sites.
Most people find it difficult to choose between one electrical appliance and another of the same type, and such websites are designed to make the choice a lot easier for you.
Try to be cautious about the plugs and safety measures before buying the electrical appliances. Make sure that you rely on the trusted sites.

Thus these are the best buying tips in order to buy the electrical appliances either from offline or online stores and know about all the specifications and their functioning.

The Disadvantages of Computer

Computer is one of the major inventions we have seen in our life. Initially long and tough calculations could not be solved by calculators or hands or other devices. We needed something extra powerful to perform the task of calculations and hence process the data into meaningful results. So with the invention of computers, our problems were solved and it began to be used in various business purposes, home purposes, even scientific and educational purposes. Today, computers have become a part of our life and we are so addicted to it that without it we will have to suffer a great loss in our life.

The computer technology has given us Internet which is used to access information by sitting anywhere in the world and even communicate with others. Internet facilities are the emailing, browsing websites which has helped students as well as professionals to grow their knowledge and be successful in other areas of work. But because of the evolution of internet and its widespread growth, we are seeing many disadvantages of using computer. Let us discuss some disadvantages of computer which thus makes computer and its technology harmful for everybody.

1. Harmful for teenagers
The computer is changing the mind of teenagers and college going students because of their own personal computers having internet facility. They try to browse all those porn or those forbidden sites. They have learned hacking the trusted passwords of companies and destroying all their useful information thus committing the crime. Students learn all that is apart from their studies and that is the use of weapons and other armaments and information on making dangerous bombs or alcohol and drugs. Another disadvantages of computers for teenagers are the violent computer games that they are so busy in it; and stop doing their homework, watching news and forgotten the current affairs of their country. They have become lazy enough to just sit on the internet or play games. These games have made them even shoot their hated colleagues. Even children have become obese and do no exercise to stay fit and fine. Parents should be extra attentive to know what their children are doing.

2. Harmful for companies and banks
Other disadvantages include frauds on internet banking by the various hackers who break the code and password and making the balance zero. Even online shopping is becoming perilous just because of the so called internet and the skilled hackers who have not left even hacking the credit cards or ATM cards.
Thus all the companies are losing their confidential information and word of mouth with their customers and hence for them internet is not a boon as it was previously. In terms of security, the customers are losing trust be it various credit card companies or banks providing internet facilities.

Thus we see that if computers have the advantages then disadvantages are also not far behind. So nowadays a law is made to arrest all those who commit the crime to browse the porn or prohibited sites or hacking the useful information of people.

How do fuel cells work?

Have you ever heard of the name fuel cells?
Fuel cells are basically electrochemical conversion device which means that it generates electricity by a chemical reaction. They produce electricity at the electrodes placed in the electrolyte. The electrolyte carries electrically charged elements from one electrode to the other, and a catalyst,
which speeds up the reactions.

Fuel cells are completely different from the electrochemical cell batteries as the latter store the electrical energy chemically in a closed system. But the fuel cells consume the reactant which must be refilled. As compared to the electrochemical cell batteries the electrodes in the fuel cells are catalytic and stable.

Fuel cells find their most of the use as power sources in remote locations such as remote weather stations, space crafts, massive parks, countryside locations and in military applications.

Fuel cells use hydrogen to produce electricity and even provide solutions to have a clean country as they produce electricity with very little pollution. The reason behind is that fuel cells using hydrogen and oxygen as an oxidant produce natural byproduct, water.

How does it really work let us discuss it in detail:
The basic purpose of the fuel cell is to produce electricity and direct it to outside to start a motor or illuminate the bulb. And the chemical reactions are most important for the working of the cell.
What exactly happens is; that the hydrogen atoms enter the fuel at the positive electrode and gives off its electrons. Thus the hydrogen atoms get positively charged. The electrons which are negatively charged provide the current through the wires. The oxygen enters the fuel cell at the negative electrode and combines with the hydrogen ions and electrons to convert into water. Thus the electrolyte plays an important role in passing only the proper ions to pass between anode and cathode. If proper ions are not supplied it may lead to utter disturbance and trouble resulting in no electricity.
The only thing is that as soon as the fuel is supplied with hydrogen and oxygen, electricity will be produced. In a fuel cell, chemicals always flow into the cell so it never goes lifeless. The important thing is that it becomes very difficult to make inexpensive, consistent and proficient fuel cells.
As compared to other hydro electric power plants and nuclear plants, the fuel cells are very expensive and still not efficient and reliable.
Government, private institutes and academics and business are requiring them the most.
Fuel cells produce direct current voltage which can be used in number of things such as various transports, electronic devices such as laptops, mobile phones and even in banks and hospitals, wastewater treatment, landfills etc. Thus we see how we can generate electricity with the help of a fuel cell thus making our future technology more productive and excellent.

Information about Virtualization

Let us first know what Virtualization means?
Virtualization means to run various independent systems on a single physical computer. We simply can say the conceptualization of computer resources. It is completely a technical term which means to create a virtual version of something whether it is computer, storage device, operating system and server or network resources.

The multiple virtual systems can run on different operating systems such as Windows, Red Hat and Mac OS etc. Here each virtual machine has its own hardware as CPU, hard drive, RAM so that it appears that the virtual machines are running on the individual physical system.

Why the need to virtualize? 
It is seen that the need to virtualize is nowadays becoming very important in various organizations to minimize their use of resources in order to save energy. Since we are struggling with various other means to save the energy on Earth and utilize it somewhere else, which is why the need to virtualize is very crucial.

It is a proven software technology that has rapidly changed the IT field and changing the people way of communicating. Virtualization has helped the computer professionals to save money and time and hardware resources and to be fast and productive in their work by being flexible. It also helps us in being more efficient and easily managing the work. In has helped us in lowering the expenses, increasing the security, and improving disaster recovery processes in our systems and helping us sustain our goals.

How does it work?
With the help of virtualization you can convert the hardware into software which means the virtual machine can run on its own operating system and applications just like a real computer system. Multiple virtual machines do not interfere with each other so that you all can run applications at the same time on a single computer.

We can simply run Virtualization software on any platform. What we have to do is to create virtual machines which are the collection of files located on the host system. Then we have to configure the settings on the host system, install the OS and then we are done with it. Another way is to creating master image of the virtual image which is fully configured with the OS and the necessary applications into it. Then we can easily and quickly install virtual machines by copying the master image to get the fullest server compatibility.

Types of Virtualization: 
Network virtualization is a method of uniting the available resources in a network by splitting up the acquirable bandwidth into channels, each of is independent from the others, and each can be allocated to a particular server or device in real time.
Storage virtualization is the grouping of physical storage from multiple network storage devices into a single storage device that is managed from a central system. It is frequently used in storage area networks (SANs).
Server virtualization is the disguising of server resources from server users. The purpose is to spare the user from having to manage complex details of server resources while increasing resource sharing and consumption and retaining the ability to expand later.

Thus we see how much Virtualization is important to manage our resources easily, save energy, time and money.

Computer Scanners

Imagine we need to send our mark sheets to a particular company wherever we have applied for the job and that company is asking to mail those documents. But we have the mark sheets of paper which obviously we cannot send them by mail. But all we can do is to get them scanned by a Scanner, then save it as a file on the computer and finally attach them while mailing it to the company. So we see that how useful scanners have become.

Computer scanner is a special electronic input device which is used to scan the pictures, text, various objects and converts into digital image. Initially we suffered a lot of problems when scanners were not made but technology is always at its best providing something or the other; daily fulfilling our desires and enhancing our pleasure.

One thing to keep in mind is that scanners do the same work just like our photocopy machine. The only difference we see is that photocopy machine gives out complete copy on the papers but in scanners any image gets stored in the computer’s memory in the form of a file and further can be saved on a hard disk and hence can be easily sent to other people by mail, or you can even write onto your CD or DVD or in pen drives. The scanners actually scan the picture or an object and thus convert it into digital image in the form of ASCII code which is only readable by the processor of the computer and thus gets stored in a file.

There are various kinds of scanners available such as Sheetfed Scanner in which the paper to be scanned moves but the scanning head is fixed. Flatbed Scanner is the one in which paper is placed on the flat surface but the scanning head moves to scan the image. This is a very common and affordable scanner. Another we have is the Handheld Scanner which as the name suggests taken in hand to scan the items or objects or information on the paper. It can be used for fast scanning the text or picture but it gives low quality images.

Other scanner is the Drum Scanner to produce high quality images and which is mostly used in the publishing industry. Here paper to be scanned is placed on a glass cylinder inside which there is a sensor which splits the light into 3 colors and with the help of photomultiplier tube changes the light into electrical signals.

Hence we see that scanners are important for us as they are used by people for their personal and professional life by making our life more fast, efficient, and successful and making us more technical.

Downloading Precautions

There are various websites available on the Internet from which we can easily download latest softwares, movies, music, games and other videos. But we never imagine that there are dangers associated with downloading which if not worked upon, can definitely fail our PC by bringing some malicious code. There are various hackers, phishers and spammers that can steal our information and erase our data.

Let us provide you with important precautions while downloading on your PC.
First look out for the reliable and trusted site to download. After finding the site, type the name of the site in search engine and read all the reviews, feedback, testimonials, etc. from actual customers.
Make sure that the site has free customer support, 24 hour support or email support as an added bonus.
The site needs to have a reliable merchant account that guarantees its products. This is truly important because the customer is always protected and can get refund if he is not satisfied by the products.
The site should be high volume friendly and can handle huge amounts of traffic with great speed.
Keep all the virus scan software active while downloading as they can scan the files downloaded into the memory and hence save your computer.
You should invest in the good spam blockers and anti-phishing programs. These programs block surrounded programs from ever getting onto your computer.
Always go for that website where there is no adware or spyware, or that your personal info will ever be sold to anyone.
When you are paying for a product then make sure that the site is legal. You check it if you see https:// as it means that it is a safe site. Also make sure that the receipt is emailed to you.
Various malicious tricks are hidden in some of the webpages which can be wonderfully blocked by the web browsers such as Mozilla Firefox or Internet Explorer.
Always allow automatic updates for Windows and virus scanning programs. These programs are often updated to deal with new threats.
You should use the latest versions of downloading softwares. These programs often have the pop up window that tells you about the new updates. Many of these updates are designed to prevent unauthorized access to your computer. So download them as soon as you can.
Never click on those links in your email that ask for your private information such as such as name, birth date, bank account, credit card number, Social security number, etc. because banks and legit businesses will never ask for this info in an email or over the phone.
While downloading, always choose save to disk when downloading because your virus software scans the download for viruses.
You should check the extensions carefully. Common dangerous extensions include .exe, .scr, .com and .vbs. These file extensions are an indicator of unsafe downloads.

Thus these are the safety precautions that should be considered while downloading.

Comparison between Satellite and Cable TV

The difference between satellite TV and a cable TV lies in the technology. What is a satellite TV? What is a cable TV? How do they work? How are both the technologies similar? Which one is better? These questions will bring out the difference between the two. So, let us explore them.

What is a satellite TV? 
Satellite television is the television which uses the communication with the satellites for the transmission of the television signals. Satellite television uses wireless technology to relay the channels on your television. This is used in all the countries on this globe to provide the consumers with different channels and television services.

How does the satellite television works? 
The satellite TV setup comes with a parabolic dish with an antenna. The signals transmitted by the antenna of the parabolic dish are taken up by the transponders of the revolving satellite which again retransmit the signals back to the earth but at different frequencies.

What is a cable TV?
Cable TV helps you to view different channels due to the different radio frequency signals. Coaxial cables or fixed optical fibers are used for this purpose. This technology is used widely in the countries where the satellite transmission is not so much useful or proper due to the geographical or climatic conditions.

How does the cable TV work? 
Different television programs and channels are prepared and broadcast around the world. These television programs are then transmitted to the satellites revolving around the earth in a particular orbit at a particular distance from the earth. These satellites resend the signals back to the earth at different frequencies which are picked up by the local satellites servicing for the particular area.

The control centers of the cable TV companies then process the satellite signals in combination to the signals for the local TV signals. This combination of signals are relayed to your TV sets through the cable wires which are either laid down either underground or extended from pole to pole to reach your destination.

What is the difference then? 
The difference is in the technologies which we have already discussed. One is the wireless technology while the other is uses a combination of satellites and cables to transmit the channels to your TV sets.

The satellite TV channels are transmitted in the digital form thus you receive high quality of the channels transmissions. The numbers of channels which are relayed through the satellite TV are exceptionally larger than that of the cable TV. Moreover, as the satellite TV providers do not have to pay the taxes levied by the government thus this services is comparatively cheaper than the cable services.

How Important Is SEO Technology

Technology is all about using the so called sophisticated scientific and technical tools which ultimately help in making our lives better by solving our problems and making us more advanced. We all remember how man himself lighted the fire, cooked the food, and made wheels for his own transportation, even scribbled on the walls and so on. That time was completely unknown of the future technology that will come and will take the generations under its control. If we talk about Computers, they have served us in a long way by solving our toughest problems and thus are today very useful for a common man. The recent developments have made them more portable enough for easily carrying them anywhere e.g. Laptops, palmtops, PDA’s. But the major development in computers is the Evolution of Internet.

Internet helps in easy information access and communication and data sharing with others. Various Search Engines are designed to search for particular information on World Wide Web (www). WWW is a storehouse of information and thus we can access information easily.

First let us know how search engines work

Web search engines work by storing information about many web pages, which they get back from the WWW itself. Search engine consists of various programs known as Crawlers or Spiders which help in getting the data in the form of web page on a specified keyword entered in search engine. The contents of each page are then analyzed to determine how it should be indicated. Data about all the web pages is stored in an indexed database which the spiders make use of, for searching the information.
When a user types a keyword into a search engine, the search engine investigates or inspects its indexed database with the help of spiders which thus provides a list of matching web pages and links thus helps us in gaining knowledge.

Now talking about the SEO Technology is far more important:
SEO (Search Engine Optimization) Technology is a technology that is very crucial for the various business transactions online. It has come into vogue over the last few years. Also called as Organic SEO, this technology is useful in bringing in the desired traffic of users who are finding a relevant websites using search engines thus helping your online business grow. You sometimes worry about your business may not be growing or proper sales of your website even if you are having very good and detailed information. But its use will increase your percentage of business without extra investment.
Usually, SEO is integrated during the designing of a website and the optimization is done by controlling and editing the content of the website and HTML (HyperText Markup Language) to increase its efficiency and attracting various internet users and thus help in the popularity of their website. It means making more profits and more money.
The key components of SEO technology begin with the proper use of relevant keywords that concern to the focus of your website. Initially this technology was costly because few trained people used to do it but now anyone can learn through various SEO tutorials and software packages available which will ultimately prove a boon for website success. It acts as a completely different marketing technique.

Hence we see that everyone wants to make money and want their websites grow and popularize. And nowadays SEO Technology has proved its need to most of the online business transactions attracting large traffic of users thus satisfying clients by delivering best results by being effective, precise and reliable.

Best Cisco tips for a Successful Systems Approach

How to Build an Electric Car

Rising fuel prices and increasing level of pollution is forcing individuals worldwide to search for alternatives technologies. Solar water heaters, solar heating system, use of geothermal energy, vehicles with improved fuel efficiency, battery driven vehicles, hydrogen cars and hybrid cars are some on the alternative technologies which are commonly used by the individuals so as to bring down their monthly electricity and fuel bills and make their planet a better place to live in. Electric cars are also a step in this direction.

Electric cars are the cars which run on batteries. You don’t have to fill fuel to run it. For them you just require a pair of batteries and a charger to charge it. The engine of the electric cars has a series of batteries which is attached to a switch and this switch is in turn attached to the electric motor. The power is supplied by the battery which runs the motor and this motor in turn drives the wheels.

How to build your own electric car? 
Although the electric car appears simple in construction but if you aim to convert your gasoline vehicle into an electric car then indeed you have taken up a daunting task. Electric vehicle kits are available in the market which helps you to convert your gasoline car to an electric car.

An electric car simply has a series of batteries and an electric motor. To convert your gasoline car you have to remove most of the components that make up your car. The task thus needs some conceptual clarity with the cars. Therefore if you want to convert your fuel car to one which runs purely on batteries then first step should be to educate yourself well about the gasoline cars and the electric cars. Understand the car mechanics before you shed the parts of your car.

The job is half done once you are clear with the basics. You now just need to remove the parts, make your vehicle light in weight, place the electric motor and the batteries and interconnect them to run your own electric car. The conversion kits along with the conversion manual are available in the market. These manuals have step by step instructions which guide you to construct your own electric car.

But not all cars can be converted to electric cars. Chevy Geo especially a model of 1989 to 1999 times can be converted to an electric car very easily. Besides these, Chevy Sprint and Suzuki Swift also readily take up the conversion.

What is the cost of conversion? 
The conversion is a one time cost. The kits can cost you around $8000 to $10,000. But this is a one time investment. You recover the amount from the amount that you save on fuel.

Cellular technology

We are aware of the different types of mobile handsets used that are coming with completely different features and high-end specifications and is very helpful in every field for getting the productive and excellent results. Mobile handsets have brought a revolution in the telecommunication industry.
It is with the help of this drastic change in the telecommunication, everybody is getting the perfect benefits in terms of communication and computation. By deploying cellular technology in an organization, it will help the employees to access databases, order products and retrieving technical specifications or off site sales staff responding to customer inquiries.

There are six basic components found in most of the cellular systems which tells us the inside features of the cellular system design. Let us have an understanding of the cellular system.

1. Mobile station
A mobile station is basically a mobile or wireless device that contains a control unit, a transceiver and an antenna for data and voice transmission. The very example is in GSM networks where mobile stations have mobile equipment (ME) and the SIM card.

2. Air Interface Standard
There are three main air interface standards such as time division multiple access (TDMA), code division multiple access (CDMA) and frequency division multiple access (FDMA). These air interface standards allow many mobile users to share simultaneously the fixed amount of radio channels. These standards are basically the medium access control (MAC) protocols that define the rules for units to access the communication medium.

3. Base Station
It is the fixed station in the mobile cellular systems used for radio communications with mobile units. Base station consists of radio channels and transmitter and receiver antenna mounted on a tower.

4. Gateway
This gateway is the communication link between two wireless systems or one wireless and other wired system. The logical components in gateway are Mobile Switching Center (MSC) and interworking function (IWF).
MSC helps in connecting the cellular base stations and the mobile stations to the public switched telephone network (PSTN) or other MSC.
IWF helps in connecting the cellular base stations and the mobile stations to Internet and perform protocol translation if needed.

5. Databases
They are also the most important feature of cellular technology. Home Location Register (HLR) and Visitor Location Register (VLR) are the two main databases used.
HLR is the database that contains the data of those subscribers that reside in the same city as MSC. The VLR provisionally stores the information for each visiting subscriber in the coverage area of a MSC.
The VLR is actually the database that supports roaming capability.

6. Security mechanism
This mechanism helps the subscriber to access the particular network and also to validate the billing for him.
The databases used for security mechanism are the Equipment Identify Register (EIR) and Authentication Center (AuC).
The EIR is the register that identifies stolen or fraudulently altered phones that convey identity data that does not match with information contained in either the HLR or VLR.
The AuC administers the actual encryption and confirmation of each subscriber.

Thus we learn about the major components and help us in knowing the cellular architecture.

Generic Projection Lamp

Generic lamps are basically the similar in temperament or copy lamps but not manufactured by the OEM lamp manufacturing company. These lamps are made by the brands like Osram, DNGO and Arclite. A generis lamp costs less as compared to the OEM made lamps because of various reasons.
The very reason is that it involves inferior workmanship quality.
It includes lower manufacturing costs.
The lifespan of the product is poor and inconsistent.
It offers poor luminosity and premature inner failure.

There is lot of difference between OEM lamps and other generic lamps. The OEM manufactured lamps last 3 times even if you need to pay bit extra.
There are lots of risks associated with generic or ordinary lamps such as premature explosion and loss of lumens.
They are not as bright as the original manufacturer.
These generic lamps last only for about 6 months and 1 year. Thus for the cost-benefit options you should consider buying the OEM lamps.
An original lamp is made to work more efficiently and last longer. The lighting element inside a UHP lamp is built to resist consistent use ignition from the weight at 20,000 volts at a time. But the generic lamps are just made to work with original lamp drivers, not taking into consideration the life span or the weight of heavy volts.
In the OEM lamps the arc gap is typically 1 mm and the electrical arc must be aligned accordingly. But the generic lamps have a shorter life span and lose luminosity over time by imploding faster.
If you have the Philips VHS lamps then you do not have to worry about the defects and they are usually used in home theater lighting, digital projection lighting thus useful in saving power.
Most of the DLP and LCD projections systems use Philips as their OEM but here the generic projection lamps are not preferred.
Philips has worked in tandem with multiple television manufacturers to develop the best lamp drivers with the best lamps. Lamps must not only be compatible with the lamp driver, but work as one unit, something you won’t get with off-brands, or third-party manufacturers.
An OEM lamp will never fail prematurely, and will always be the best choice because it’s designed to be 100% compatible with your lamp driver, or ballast. But the same problems will appear in generic lamps.

Thus these generic projection lamps are not at all the preferred lamps because of their low quality and low luminosity, poor lifespan and premature implosions. These generic lamps though are inexpensive on your pocket but lack in quality. So it is always preferred to use the original, high quality made lamps from OEM or Philips brands.

Automatic Transmission Fluid

This is the red colored highly refined mineral oil that is used in the vehicles with automatic transmission. The use of automatic transmission fluid differs with different systems. It is used as a lubricant and as hydraulic fluid in different vehicles.

There are three types of automatic transmission fluids. These are Dexron, type F and ATF+. The user manual list the type of ATF used in the vehicle. The manufacturers sometime refer different types of ATF products for different types of vehicle usage.

Modern automatic transmission fluids are formed from a combination of different types of chemical compounds so as to develop a particular ATF specification. These compounds can be anti foam additives, detergents, anti wear additive anti oxidation compounds, high temperature thickeners, petroleum dye and cold flow improvers.

To optimize the performance of your vehicle and its components it is important to perform a routine checkup of the fluid in your vehicle. For this park your car on a level surface and start the engine.
Keep the engine running till it warms up.

To check the ATF in your car keep the engine running. But with some cars it is not required to run the engine while you perform the check up. Therefore consult the user manual before you start the process.

Now with the ATF dipstick check the level of the fluid. This dipstick is similar to the engine oil dipstick but somewhat smaller in size. But before you use it wipe it either with a rag or a cloth for the purpose. Push it in the engine and then remove it. Scan it carefully for two different marks.

One mark is for warm and the other is for cold. Note the mark for warm reading. Now if the automatic transmission fluid does not reach up to the full mark it means that you have to add the fluid to your vehicle.
This is the fluid which is not used up when you drive your vehicle. Therefore if there is low level of fluid then this means that there is some kind of leek. Check your vehicle. Don’t ignore the fault as it may lead to some transmission repairs.

Consult the user manual to find out the type of ATF recommended by the manufacturer for your car. Purchase it and add the fluid in the small hole from where you took out the dipstick. Add slowly.
Don’t overfill the fluid. Overfilling leads to automatic transmission failure. The correct way to add the fluid is to pour slowly using the funnel and checking it simultaneously with the dipstick.

Some new vehicles don’t come with the dipstick. If you own such vehicle then don’t experiment. Find an experienced mechanic to add the fluid to your vehicle.

Importance of Simplicity in Technology

Technology is growing day by day and we are getting the latest products with the high-end specifications and features. The more the technology is advancing we are getting the many sophisticated gadgets and gizmos. They are very exciting to have in our hands but the main feature that should be seen in them is how simple they are! The design, appearance and fun factor are the preferred with the simplicity in mind.

Our lives though loaded with high technology that promises power and convenience, it leaves us fuming in frustration over jumbled software and hundred-page user manuals. So first and the foremost option is making the device very simple and user friendly. Technological success demands simplicity and it is the key factor which every brand company takes into consideration before devising any device.

The Beauty of Simplicity

1. Portability
The beauty of simplicity lies in the smaller and compact devices in the field of media and entertainment. As we can see the bulky CRT TV sets are replaced by the LCD or Plasma TVs. The music players in our homes have now become handy. Thus they are sleeker and smoother fulfilling our entertainment and our needs. The main thing we see that they are simple and anyone can handle them easily without the fear of being damage.

2. Size and budget
Other things that make the gadgets simple are compatibility and high storage facility. For example Xbox 360 is a high end specification and massive technical specifications. They are large, loud, and way too powerful for any game. They even require HD televisions, big sound equipment, wireless broadband internet access, and a dozen other things that not everyone can afford. So these things really make us think that are the simplest ones are Nintendo Wii which requires less support, less money, and less tech happy exploitation of finances. So budget is also the main simplicity factor.

3. Storage capacity
The basic reason behind the popularity of Nintendo Wii is 3D gaming and high storage capacity. With all these features the gadgets become simple to buy which are not very heavy on our pockets. Here the compatibility and high storage capacity speaks a lot.

4. Accessibility
The products have a user friendly interface, most attractive design, straightforward and stylish options that anyone can handle them. Thus the accessibility is also the main concern of simplicity in technology.

It is just to simplify the technology without sacrificing comfort and meaning. It is about subtracting the obvious and adding the meaningful. So if you want to add popularity to your product then it is necessary to add simplicity into it.

Facts about the Solar System

We all know that our solar system consists of nine planets all of them revolving around the sun. But there are other interesting things which most of us don’t know. I discovered some while browsing through different websites. So, here I will share with you some interesting facts related to the fascinating system.
The gases and dust particles assembled billions of years ago and started the formation of solar system. They all assembled to form the sun and different planets.
The sun is one among the several stars that you see in the night sky. This is the star which lies close to our planet and hence we all feel the heat. There are 70,000, 000, 000, 000, 000, 000, 000 stars in the universe and sun is one of them.
The sun is surrounded by Mercury, Venus, and Earth. Then there is an asteroid belt after which Jupiter, Saturn, Neptune, Uranus and Pluto follow. The first three planets near the sun are the dense rocky planets while the other planets which lie after the asteroid belt are less dense gas planets. There are dwarf planets as well. These are Ceres lying in the asteroid belt, Pluto and finally the Eris located miles beyond Pluto.
Asteroids are the rocky planets that lie between the Jupiter and Mars orbit. These 90,000 asteroids are the remains of the solar system when it was formed.
Sun forms about 99% of the solar system. Besides planets and asteroids there are 172 moons of different planets, comets and dust.
Our earth is hit by about 10,000,000 kg of meteors everyday. So, lots of dust falls on our planet everyday.
The Saturn is one such planet in our solar system which will float on water if it is placed on it. That’s true! The planet is less dense than the water and if any such thing happens then it would be great to see.
Winds on Neptune are moving at the speed of 2000 km.
Mercury might be the nearest to the Sun but Venus is the hottest planet of our solar system.
Jupiter is the largest one. It is so large that it can hold around 1300 earth in itself.
Pluto takes 248 years to complete one orbit around the sun. It was discovered in 1930, so, we will celebrate its first orbit anniversary in 2178.
The red spot on Jupiter is the hurricane storm.
When Pluto is close to the sun its atmosphere is thin but when it is far away then its atmosphere freeze so that the collapse on the planet and Pluto resembles a comet.
The comets are lumps of ice which come from outer space into our solar system. When they come close to sun then the nucleus sublimates forming a cloud of dust and gas.

All these facts which listed here are just the tip of the iceberg. I suggest you to browse the websites and discover your universe yourself.

These scanners were very costly in the early times but now their price has been reduced.

These Bluetooth wireless barcode scanners are gaining popularity in every retail or industrial areas in order to give the perfect satisfaction to their customers while selling out their products.

About Different Network Topologies

Network topologies mean the physical layout of the network combined with its logical characteristics. The physical topology or layout refers to the configuration of cables, computers and other peripherals. Topology is the standard term used by the professionals when they refer to the network basic design. While setting up the layout of the network it is necessary to know hat type of equipment the network needs, its capabilities, growth of the network and the way in which network is managed.

There are four basic topologies that are used in the network design. Let us discuss them below.

1. Bus Topology
Bus topology is considered as the “linear bus” because the computers are connected in a straight line. This is the simplest and most common method of network computers. Bus topology has the main run of cable with a terminator at each end and all nodes such as computers are connected to linear cable.

Advantages 
Easy to connect and easy to handle and implement.
It is best suited for small networks only.

Disadvantages 
The cable length is limited and because of which the stations are limited.
Entire network shuts down if there is a break in the main cable.
It becomes difficult to identify the problem if network shuts down.
Not meant to be used as a stand-alone solution in a large building.

2. Ring Topology
This topology connects the computers on a single circle of cable. The signals travel around the loop in one direction and pass through each computer, which can act as a repeater to boost the signal and send it on to the next computer. It has no terminators at the end and thus is very different from the bus topology.

Advantages 
Here a central server is not required for its management.
Easier to manage as compared to the bus.
Provides good communication over long distances.
It handles very high volume of traffic.
It is very reliable.

Disadvantages
The failure of a single node of the network can cause the entire network to break down.
The changes made to network nodes affect the performance of the entire network.

3. Mesh Topology
His topology offers best redundancy and reliability. Here each computer is connected to every other computer by separate cabling.

Advantages
The arrangement of the network nodes is such that it is possible to transmit data from one node to many other nodes at the same time.
You get the redundant paths so that if one cable fails another cable will take over the traffic.

Disadvantages
It is very expensive to install as there are lots of wires used in it.

4. Star topology
In this topology the cable segments from each computer are connected to a centralized component called a hub. Here the signals are transmitted from the distributing computer through the hub to all other computers on the network. The hub only manages and controls all the functions of the network.

Advantages
Easy to install and wire.
No disruptions to the network then connecting or removing devices.
Easy to detect faults and to remove parts.

Disadvantages
It requires more cabling than linear bus topology.
If the hub fails, nodes get disabled.
It is more expensive than linear bus topology.
Thus these are the various network topologies used in the organizations depending on the cost, length of the cable required, types of cable and future growth of the network.

Some Achievements of Isaac Newton

Everybody must be aware of the name of the famous scientist and mathematician named Isaac Newton. He made great achievements in mathematics, optics and physics; laid the foundation of modern science and thus brought a new revolution in the world. Who can forget the famous Newton’s Laws of motion! He was the first one to discover the relation between external force and motion.

Sir Isaac Newton was born in 4th January 1643 and was an English physicist, mathematician, astronomer, natural philosopher, alchemist, theologian and one of the most influential men in human history.

We have heard all about his greatest achievements so let us know about them in detail.
The Newton’s Laws of Motion became the founding principles of mechanics and told to people about the relationship between force and motion. He published his works in the ‘Philosophieae Naturalis Principia Mathematica’ in 1687. The 3 laws of motion were: - Law of Inertia that says that every object remains to be in a state of rest or motion unless acted upon by the external force; Law of acceleration which states that force is equal to the momentum per change in time and Law of action and reaction which states that every action has equal and opposite reaction.
Newton even devised the law of Universal Gravitation which says that all particles of matter in the universe attract every other particle, that gravitational attraction is a property of all matter. The law explained many things, from the orbits of the planets around the sun to the influence of the moon and sun on the tides.
Newton also discovered Calculus which was a great achievement in the field of mathematics. The various properties such as direction and speed which are in the continuous state of change with time was told by him. With the help of Calculus, Newton could determine the length of curves, draw tangents to curves and solve problems in classical geometry. It is because of this that he could work easily on the astronomical research.

What is Biometric Technology?

It is the technology that measures, analyze and record the characters unique to the individuals. The characters are physical and behavioral which either remain same or change negligibly over time. This includes the fingerprints, DNA matching, iris and retina pattern, and behavioral characters such as handwriting, voice and typing patterns.

The characteristics are recorded by either taking the complete image or by taking partial image. The fingerprint is an example of complete image approach where the complete image is recorded and is further used for verification. While in other approach, complete measurement is taken but only the uniqueness in the character is recorded.

Biometric technology thus results in the automatic recognition of the individual. It is advantageous over the traditional form of recognition used because firstly, the physical presence of the individual is required for identification.

Secondly, the process does not involve the use of PIN number or passwords. Besides this, the physical and behavioral characters are unique to the individuals. They cannot be hacked like the passwords and PIN number. This provides for safe and authentic identification of the individual.

Broadly, the biometric technology performs two important functions of authentication and verification. This process involves four steps:
Registration.
Allocation.
Verification.
Recognition.

Biometric system

Biometric system consists of a sensor, extractor, template generator, storage template and the matcher. The sensor extracts all the data. This data is then pre processed so that all the unnecessary part are removed like the noise etc. and the data is stabilized.

Form this processed data essential characters are extracted. From these features template is created. Now the template is either matched or stored. The matching process is the test while storing new data is enrollment.

To match or test, the received data is passed to the matcher for further processing. To enroll or store, the received data is passed to the storage unit where the information is simply stored for verification in future.

Application of biometric technology 
The technology finds wide application in the forensic. It is used in criminal identification. It is also being used in different organizations. Biometrics is used in government organizations as tool to fight security threats. In colleges and schools the fingerprint and palm prints are used to record the attendance of the students.
