2. Mainframe Computer
A mainframe computer,
informally called a
mainframe or big iron, is a
computer used primarily
by large organizations for
critical applications like
bulk data processing for
tasks such as censuses,
industry and consumer
statistics, enterprise
resource planning, and
large-scale transaction
processing.
3. Workstation computer
A workstation is a special
computer designed for
technical or scientific
applications. Intended
primarily to be used by a
single user, they are
commonly connected to
a local area network and
run multi-user operating
systems
4. supercomputer
A supercomputer is a
computer with a high
level of performance as
compared to a general-
purpose computer. The
performance of a
supercomputer is
commonly measured in
floating-point operations
per second instead of
million instructions per
second.
5. Personal computer
A personal computer (PC)
is a microcomputer designed
for use by one person at a
time. Prior to the PC,
computers were designed for
-- and only affordable for --
companies that attached
terminals for multiple users
to a single large mainframe
computer whose resources
were shared among all users.
6. Micro computer
A microcomputer is a
small, relatively
inexpensive computer
having a central
processing unit made
out of a microprocessor.
The computer also
includes memory and
input/output circuitry
together mounted on a
printed circuit board.
7. Desktop computer
A desktop computer
includes the processor,
which can be a
minitower designed to
fit under the desk or a
unit that goes on top of
the desk. It also
includes a
motherboard, the main
circuit board for the
computer.
8. minicomputer
A minicomputer, or
colloquially mini, is a
type of smaller general-
purpose computer
developed in the mid-
1960s and sold at a
much lower price than
mainframe and mid-size
computers from IBM
and its direct
competitors
