(a) Keyboard.
The keyboard is one of the computer's input
devices.
It has the same basic arrangement as a typewriter keyboard,
with the addition of more keys.
The keyboard has 10 function keys
labeled F1 through F10.
These keys perform different functions as
dictated by the program in memory.
Most keyboards have a numeric keypad. This part of the keyboard has the
same layout as a business calculator. When activated, this part of the
keyboard functions the same way as the keyboard of a calculator (figure
1-77).
