Numeric Keypad

KEYBOARD

The keyboard is the key control unit of the PC. It is used for input of the alphanumeric (sign) data, and also commands of handle.

You usе the keyboard to type instructions for your computer, and to type information you want your computer to process. All keyboards have letter keys, punctuation keys, and a spacebar. Most keyboards also have function, numeric, and arrow keys, in addition to ALT, CTRL, DEL, and ENTER or RETURN keys.

Their placement on the keyboard is determined by the computer manufacturer; how they are used is determined by the software you are using.

Because the number keys are grouped together on the numeric keypad, the keypad is a quick and easy way to type numbers. With many software products, you must press the NUM LOCK key before using the numeric keypad to type numbers. The NUM LOCK key works somewhat like the CAPS LOCK key on your typewriter. When you press the NUM LOCK key on the numeric keypad, the numbers you press on the keypad appear on your screen.
