Abstract
Computing is a process which, like many other processes, can be simply stated to comprise three basic components
-
(a)
an input(s),
-
(b)
a processing facility(s) and
-
(c)
an output(s)
which are connected as shown in the following diagram
It can be seen that the processing facility takes an input(s), processes it and then, as a result of the processing, produces an output(s).
