About the Keyboard

The keyboard is where the data or information is input into the computer. It is usually arranged like an ordinary typewriter keyboard with a number of other keys added which carry out special functions.

1. Alphanumeric keys: arranged in the same order as a typewriter.

2. Function keys: used by various programs to instruct the PC to perform specific tasks, such as Save, Copy, Paste, Help, etc.

3. Numeric keypad: set of numeric or editing keys. The NumLock key is used to switch from numbers to editing functions.

4. Editing keys: cursor and other keys usually used within word processors to page up and down in a long document or to edit text (using Insert or Delete keys).

5. Special keys: used to issue commands or to produce alternative characters in key combinations, for example, the Alt key.
