KEYBOARD

A computer keyboard looks and functions just like a typewriter keyboard, except that computer keyboards have a few more keys (for navigation and special program functions). When you press a key on your keyboard, it sends an electronic signal to your system unit that tells your machine what you want it to do.

TIP

Wireless Keyboards

If you want to cut the cord, consider a wireless keyboard or mouse. These wireless devices work via radio frequency signals and let you work several feet away from your system unit, with no cables necessary.
