Using a Keyboard

The keyboard is the most common type of input device. The keyboard takes in information in the form of letters and numbers. The letters and numbers are translated into instructions that the computer must perform. The computer translates literally what is entered, so any typing mistakes will result in an error.

Certain aspects of keyboards are important to consider. For example, choose a keyboard that is comfortable for you. In most cases, it is beneficial to select an ergonomically designed product. These products are designed to blend smoothly with the contour of your body.

Keyboards can connect to computers in several ways. The most common type of connection is the DIN 6, which is also referred to as a PS/2 connector. The DIN 6 connector is small and looks identical to a PS/2-style mouse. It is easy to confuse these two when connecting them to the computer.

Some computers still use the older AT keyboard connector that was originally used in the IBM PCAT computers introduced in 1984. The AT was replaced by the more recent PS/2 connector. Like the AT-type connector that is rarely if ever specified for a new computer, the PS/2 is experiencing some competition of its own from Universal Serial Bus (discussed earlier in this chapter). The PS/2 connector won't disappear soon, but with Apple Computer shipping USB-only keyboards, don't expect the PS/2 to be around forever.

Warning 

Don't unplug the keyboard or mouse while the computer is on. You might damage your computer with a static charge. Also, some computers may need to be rebooted to recognize the reconnected devices.
