Digital Computer!
Classify and discuss different types of digital computer.
There are four types of
digital computer:
a). Micro computers;
b). Mini computers;
c). Main frame computers;
d). Super computers;
Micro computer:
In which the various
integrated circuits and elements of a computer are replaced by single
integrated circuit called a “chip”. Examples are the IBM pc, Apple Macintoshes,
Dell.
Their continuing and rapid
technology development had a major effect on the whole computer industry over
the past twenty century.
Mini computers:
Physically small computers compared
with mainframes. They are used for special purpose or smaller scale general
purpose work. Example are DEC’S, VAX, RANGE.
Mainframes computers:
Large general purpose
computes with extensive processing, storage and input/ output capabilities. The
market for these computers is dominated by IBM.
Super computers:
A large and very powerful
mainframe computer is called a supercomputer. The Cray X-MP is an example of
supercomputer. Such supercomputers are applied to the solution of very complex
and sophisticated scientific problem and for national security purposes of some
advance nations.
