state at one time, to count each of
its digits from 0 to 9 (a decimal

A “computer program” on
ENIAC was entered by using
wires to connect different units
of the machine as to perform
operations is a required
sequence. The picture on the left
shows two women entering a
program, which was a very
difficult task. The machine was controlled by a sequence of electronic pulses, in which
each unit on the machine could issue a pulse to cause one or more other units to perform
a computation. The control and data signals on ENIAC were identical, typically were 2
microsecond pulses placed at ten microsecond intervals, which could allow for the output
