the transferring of information into a computer system - for our
purposes this will be accomplished when you, the programmer, type
source code at the keyboard or open a previously typed program.

the manipulation and control of information within the computer
system. Such manipulations are handled by the Control Unit, the
Arithmetic Logic Unit and Temporary Storage.

the means by which information can be "permanently" saved (until
such time as you wish to delete it). This usually occurs on a hard
drive, a diskette or a CD.

accomplished when your programs display information on the monitor. |
