Computers cont...
Information provided to the computer program is called input. Input can arrive via various sources
such as a keyboard, a mouse, a barcode reader or a voice.
Once the computer has been told to do its task it must then show us the result, which is called
output. This can occur in a number of ways: on screen, on a printout, by sound or by causing
something to operate.
The real benefit of using computers appears when:
·
the same action has to be performed several times
·
you have to handle large amounts of information.
