Keyboard device drivers

Keyboard image

Keyboard is one of the most important input devices in a computer. Through keyboard, a user can input data, play games, access menus and provide inputs to her computer. The keyboard of a computer is much similar to that of a typewriter and the only difference is that a computer keyboard comes with some additional keys. A typical keyboard generally has 80 to 100 keys which are classified in to the following four main categories.

The first category is the typing keys or alphabet keys which includes all the alphabets. The placement of these keys is similar to that of a typewriter. QWERTY is the most common known keyboard layout which is named after the first six alphabets in the keyboard. Some other keyboard layouts are AZERTY, QWERTZ, XPeRT, ABCDE and Dvorak. Nevertheless, you may never need to learn any of these layouts other than QWERTY which is what you are using, most likely. The second category is the function keys. These are basically the shortcut keys for menu functions like save, help, refresh, find, and etc. The third category is the control keys. These keys include the Home key, the Arrow keys, the End key, the Delete key, the Insert key, the Page Down key, the Page UP key, the Control key, the Escape key,  and the Alternate key. The last category is the numeric keys. They are a set of seventeen keys and their placement is similar to that of a calculator.

There are also other types of keyboards that have some extra keys which are multimedia keyboards, gaming keyboards and virtual keyboards. A multimedia keyboard includes some additional keys through which you can directly access the Internet, listen to music and invoke other common programs. Other gaming keyboards basically come with additional function keys which make gaming much easier for users. However, there are even virtual keyboards which is basically comprises of a full size image of the QWERTY keyboard and it is projected on to a flat surface. When you touch an image of a particular key, a unique signal is generated through the virtual keyboard which provides the computer connected with a key stroke message.

Keyboard layouts might also vary with different manufacturers. Computer keyboard is basically based on the typewriter principle and it follows the original QWERTY layout with just a few additional keys. Earlier, transfer of data from the keyboard to the computer would take longer time as they were based either on keypunches or teletype machines. To overcome this flaw the video display terminal technology was used along with the cathode rate tube technology. This allowed the users to view what they typed and also made it easier to delete, edit or create new text.
