All over the world we can find countless people that use computers daily for doing certain activities. Most computers users have to work on certain projects but there also are many who like to relax and entertain. If you want to use your PC in order to relax, you can turn on and listen to your favorite music, you can watch a movie, play a game, browse the Internet, have a chat with other people over the web and many others.

The advantages that these great and vital electronic devices offer are countless and all of their users are very pleased with them. Besides computers are being used daily by countless people all over the world, they also are being bought in large numbers from numerous places but first of all, I must add that these devices and found in 2 out of 3 homes and all family members tend to use them for diverse activities.



Every computer has different specifications and characteristics and people purchase them based on them. The higher their specifications are, the more money you have to spend on one and if you want high performance, you have to pay a lot for it. Computers can even cost around 3000 dollars. OK, so you have the money…but from where do you buy these devices. In every city are many electronic stores that sell them in quite large numbers every day and most of the people who enter them tend not to leave before buying something they want and need. Besides the city stores, you can also purchase a PC over the Internet because there are many websites that are in fact virtual stores and from where people can purchase all the things that they want to. Making such purchases on the Internet is very easy…the first thing that you have to do is to pick your desired products, complete the order form with your personal info and then place it. After the order is placed all that remains to do is to wait maximum 3 days until it arrives at your address.



Computers aren’t so bought on the web because they are big devices made from many components but there are some inner and outer parts that are bought in large numbers. For example, the computer mouse is highly important in the usage of a PC because it is the one that offers you the possibility to browse fast and efficient through the computers folders and in other places too like the Internet. The Logitech G5 computer mouse is one of the mouse bought products from Logitech that is the most important and most popular mice manufacturer. You have here lots of things about these great outer devices that you may find useful. The Logitech G5 required a quick driver installation before using it so the Logitech G5 mouse driver plays a very important role. The driver can be found on the installation CD you were given at the purchase or you can just download it from the Internet from various websites.



The Logitech G5 mouse driver can be found in many places so installing it isn’t a problem. So, if you do not have the installation CD, you can always access the Internet and make a quick search on Google for the Logitech G5 mouse driver and you will be given lots of websites like the one from above from where you can download it.

When it comes to technology, we have to admire and appreciate its efforts made to accommodate just about everybody. Actually, it kind of has to, in order to maintain a steady flow of customers. Somewhat special are the recent innovative outbursts of computer hardware designed for the physically disabled people. Just because most of us take for granted the easy access of our fingers and hands to the keyboard and the mouse, it doesn’t mean that it’s quite that easy, if at all possible for others.

Most people have heard of Stephen Hawking. He is suffering from motor neurone disease also known as amyotrophic lateral sclerosis (ALS) which, in time, practically paralyzed him completely. Up until recently though, he still could slowly and faintly move his fingers. A great mind like his was surely in need of a computer, but he had no motor abilities like us to help him use a keyboard or a regular mouse. Still, he was given an unusual mouse which was his only interface with the computer. The cursor on the screen moves constantly, and he only needed to click the mouse in order for the cursor to select a certain word.

It’s true. There a lot of people that are physically impaired when it comes to using even such a simple thing like the mouse. Just take into consideration a person who has no arms. Sure enough, technology has made it possible nowadays for such a person to get a good mouse experience using… their feet! The mouse has a rather different aspect (depending on the producer) but its functions and mechanisms are the same as the regular mouse.

There even are computer mice for disabled people that can function with just a slight touch of a fingertip. Using motion and pressure sensors, these mice record any slight movement of the fingertip and “translate” it to a more complex virtual movement on-screen. These kinds of mice have been invented and are a good option for people who suffer from paralysis. Using just that mouse a person can perform virtually any tasks on the computer. Of course, software developers had to come up with virtual keyboards and other virtual aids integrated in the operating system to help the physically impaired person.



Other, more interesting computer mice for disabled people use laser or radio waves technology. The mouse in those cases is practically a helmet on the head of the person that has a light beam pointed toward a receiver. When the person moves his head, the cursor on the screen moves accordingly to the signal of the movement processed after the receiver sends in the coordinates. It’s more like a remote control really, if you think about it.



Even a blind person can benefit from a mouse nowadays. The mouse is specially designed to have indented characters on its surface instead of buttons for clicking. There are also a wide variety of joystick computer mice out there. These help people with locomotor impediments (locomotor ataxia for example).

Next time you handle a mouse or use a keyboard, just take a second and consider that the fact that you’re healthy and can easily do these things isn’t something you should always take for granted.

A computer mouse is a very common, very well-known peripheral hardware component of a Personal Computer (PC) that lets the user interact with the machine. Ever since it was shipped with the Xerox 8010 Star Information System it has brought to PC users worldwide a hands-on approach to handling the data stored on their computers.

The term of “mouse” was attributed to it in 1965 by Bill English, because of its resemblance with the small mammal, especially due to the cable that connects it to a computer that looks like the tail of a mouse.

So how does a computer mouse work? The first computer mice used a set of two perpendicular wheels that, when they were pressed and moved on a surface, sent electric signals to the computer which translated those signals into X and Y coordinates, thus rendering the pointer on-screen to move accordingly. But the first mouse was bulky and heavy to manipulate and soon fell out of fashion due to invention of the ball mouse.



The ball mouse uses the same principle as the wheel mouse, but instead of two perpendicular wheels, it uses just one ball. This was needed because its predecessor couldn’t move in more then two directions. The ball mouse could now move in any direction – for the wheels that transmitted the electrical impulses generated when they moved were inside, pressed against the ball of the mouse. However, even this mouse had its disadvantages. It needed a rather rough surface, because friction was very important in order to roll the ball – hence the appearance of the mouse pads. Also, its inside wheels were pretty sensitive and the ball itself carried dust from the surface it was used on to the circuits inside, thus soon rendering the mouse nonfunctional.

And this brings us to the present day. The most common mouse used nowadays is the optical mouse. This one uses a light-emitting diode and photo-diodes in the process of detecting movement relative to the surface it’s based upon. The optical mouse has a lot of benefits due to the fact that the inner mechanism has no direct contact with any surface, thus being protected from dust or other residual material that can get caught up in the circuits and affect them. Also, the optical mouse’s precision is far greater then the one of its ancestors. And last, but not least, it can very well function on most surfaces – a regular wooden desk for example – without the need of a mouse pad.

There are a few other models of computer mice that, even though they are not that common as the regular ball mouse or optical mouse, surely they have attracted attention. Probably the most well-known is the Wii Remote. This is just an example from a large array of a newer, less known category of computer mice, also known as 3D mice. They use sensors to detect any movement in a three-dimensional space, thereby demanding a larger implication of the handler in exchange for a full filled sense of control.



Now that you have a better, although still basic understanding of how does a computer mouse work, maybe next time you get a hold of the little mechanical critter, you won’t take it as much for granted.

We all are aware of the great importance that computers have in our present society. Only with the help offered by them we are able of doing many things. Most of us tend to use every day a computer for doing diverse things like working or entertaining.

The mouse (also known as pointing device) is one of the greatest inventions in computer ergonomics. With the help of a mouse the PC user doesn’t have to use his keyboard for all the clicks made on a small device called mouse or in some areas pointing device.

First of it all I would like to explain why they call it mouse and what it is exactly. The name came from its shape, because it looks like your holding Jerry, right? So while Tom was not around in 1963 with Dr. Douglas C. Engelbart (born January 30, 1925), he had time to invent the first mouse prototype at the Stanford Research Institute. But before the mouse, a secret military project invented the trackball with some help from Tom Craston, Fred Longstaff and Kenyon Taylor in 1952. When Dr. Douglas C. Engelbart invented the first mouse he named it x-y position indicator. “One of the members of the team nicknamed the device a mouse and it caught on,” says Dr. Engelbart at the BBC program Go Digital.

The mouse is a pointing device, which can be connected to the computer in several ways:
- Connected directly to an RS-232C serial port
- PS/2 mice
- USB
-Wireless/Blue tooth



I remember my first computer had a PS/2 mouse with a trackball, and sometimes gave me some nerves when the cursor jumped by it self. But after some years I bought a PS/2 optical mouse which uses a laser to detect the mouse's movement. And I was really satisfied with it. But after some more years I bought a USB optical mouse and I’m still using it proudly.

There are several mice for graphics and gaming. For example a few years ago, when Counter Strike was the trendiest game in the world, everybody bought expensive optical mice, because those are more accurate than the old-fashion trackball mice. Those who use programs like Corel Draw or Photoshop use a very expensive optical or even wireless optical mouse because of the accuracy of its pointer.  So here is the list of basic mouse types:



Mechanical: Has a rubber ball on its underside that can roll in all directions. Mechanical sensors detect the movement of the ball.

Opto mechanical: It is same as the mechanical has a rubber ball, but the movement of the ball is picked up by optical sensors, so it is more accurate than the simple mechanical.

Optical: Uses a laser to detect the mouse's movement so it is the most accurate mouse, but also the most expensive.

Dr. Douglas C. Engelbart was born in the U.S. state of Oregon on January 30, 1925 and he is of German, Swedish and Norwegian descent. Unfortunately Engelbart did not receive any awards for his invention, as his patent ran out before it became used in PCs. If I were in his shoes, I would ask for an award or something. He deserves it doesn’t he?

Here you can find some unusual mouse designs.
