Modern
computers are
very powerful electronic counting and calculating machines that can also
convert words into
numbers, rearrange them, and convert them back into
words
(word
processing). By similar
conversions they
can also draw pictures, play music, make a telephone call or
control your
washing machine. Computers have always processed information.
The early
computers could only process it in limited ways. Modern
computers, however,
can also store information in vast quantities, and this
information
includes stored
programs
that manipulate
data
in
different ways. What a modern computer does depends,
therefore, on the
program or
software
that it is using.
