What are the advantages of Audio Books for the Blind
Technology has always enhanced and enriched our life. It has made everything very easy and convenient for us. We can say that this is only the primary goal of technology to improve our lives and make us free of the daily monotonous manual work by turning everything into digital.
We have experienced all the latest gadgets and gizmos and visualized the world in our hands. But we know how tough it becomes for the blind people in this world as they cannot even see the beauty of the nature or even experience having a cell phone in their hands with multiple features. They just cannot even see the TV or go to the movie theaters, work on computers, read newspapers and textbooks. Technological advancements like computers and Internet can help us a lot in means of viewing the latest information but what about the blind people? As we have heard of Braille method which helps the blind people to read and write but it does get so expensive and not so interesting.
But still technology has helped the visually impaired people also in its own way by providing Audio Books. Before we see how the Audio books have helped the blind people let us first see what is actually an Audio Book?
Audio Books mean the audio version of the book, a simply recording of verbal words but it is not actually a book.
They are the books which we can simply enjoy and learn by just listening to them and thus acted as the best source of learning for the blind people.
These books have the verbal words which are narrated by the professional narrators and actors. It has music built into it with lots of sound effects and thus it helps the blind people to hear stories and current news updates of their country.
Talking about the advantages of the Audio Books for the blind people is that:
Those blind people who had an interest in reading novels can now listen to it with interest and excitement.
Audio books come in the form of cassettes or CDs or DVDs which you all can easily get from the bookstore. But if you really need to use Internet then you can also download them which is really very inexpensive or sometimes even free. The downloadable audio books have made the life of blind people easy.
Apart from listening to stories or news the visually impaired can also learn vocabulary with pronunciation or learn other language with perfection.
It can be very helpful for the small kids who are blind by birth as they can listen to the bed time stories daily.
Thus we see how the Audio Books, a new hope for the blind by the technology, have enhanced their lives and given them the reason to live their life to the fullest.

7 Significant Reasons To Use Computers In Your Classroom
Technology is all around us so why the classrooms in the schools should be left behind. But why should we use the technology in classrooms? The reasons can be divers but there are certain reasons as to why we should. They are:
Every student has a different level of IQ than the other. Some may be fast learners and some may grasp the things slowly. Some may just memorize the whole lecture instead of understanding while some go into too much of details. Thus there is a wide gap between the students sitting in the same room and studying the same course. The use of technology can bridge the gap between them.
The boring lectures can be made interesting by the use of the technology in the classes. The absenteeism and the class bunks can be reduced.
Implementing the technology helps the students to explore the actual use of the studies they are taking in the rooms. They can visualize how the technology is actually implemented in the real world and how they can enhance their knowledge further, what they need to learn more and the likes.
The students can find more data regarding the topics that they are studying that may be impossible to gather form other sources, save the files and make their own notes in the classroom by browsing the net and searching the websites. This data collected and saved as notes saves time and the money of the students.
The assignments given to the students can be taken up as class presentations. This not only develops the presentation skills of the students but also makes the whole study interesting and simultaneously grooms the personality of the students.
Interact with number of students simultaneously. The technology also provides one to one interaction among the professors and the students such that the professor can pay individual attention to the students in the class rooms. The students can also interact with the other students in other colleges and share their views on different topics.
The technology can be used to provide a simulation environment where the students can be given the problems and an environment that is similar to the real conditions. Thus the students get an opportunity to actually act in the situation. This makes the whole thing interesting and the students participate, come up with new ideas and actually gain knowledge of how to implement the theory into practice.
Thus the use of technology not only improves the interaction among the students, but also develops the team spirit among them, helps in developing the personality and thus the very objective of the education of developing the individual.

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.

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.

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.

Cellular technology
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.

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.
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.

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.

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.

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.
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.

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
Information about Virtualization
et 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.

How do fuel cells work?
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.

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.

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!
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!
Apple MacBook Air (Nvidia 9400M GT)
review
The MSI X340 (021US), which debuted at CES 2009 as the X320, is nearly an identical twin to the Apple MacBook Air (Nvidia 9400M GT). Other than color—our review unit was black, and there's also a silver version—it's hard to tell them apart at first glance. The X340 is a cheap Air knock-off, to put it lightly, but there's more to this exceptionally thin ultraportable than its cellar-low price. Matching the Air's weight and dimensions is an impressive feat in its own right, yet MSI adds a full array of physical ports and a removable battery, which won't find in the Air. But the X340 will need to revisit Apple's blueprints if it wants to match the Air's build quality.
