2. DIFFERENT TYPES OF COMPUTER
The four basic types of computers are as under:
Supercomputer.
Mainframe Computer.
Minicomputer.
Microcomputer.
4. A supercomputer is a computer that performs at or
near the currently highest operational rate for computers. Traditionally,
supercomputers have been used for scientific and engineering applications that
must handle very large databases or do a great amount of computation The
performance of a supercomputer is commonly measured in floating-point
operations per second (FLOPS) instead of million instructions per second
(MIPS).

6. Information :-
Mainframes are a type of computer that generally are known for
their large size, amount of storage, processing power and high
level of reliability. They are primarily used by large organizations
for mission-critical applications requiring high volumes of data
processing. In general, there are a few characteristics of
mainframes that are common among all mainframe vendors:
Nearly all mainframes have the ability to run (or host) multiple
operating systems. Mainframes can add or hot swap system
capacity without disruption. Mainframes are designed to handle
very high volume input and output (I/O) and emphasize
throughput computing. A single mainframe can replace dozens
or even hundreds of smaller servers.
8. Information :-
A minicomputer is a type of computer that possesses most of the
features and capabilities of a large computer but is smaller in
physical size.
A minicomputer fills the space between the mainframe and
microcomputer, and is smaller than the former but larger than
the latter. Minicomputers are mainly used as small or mid-range
servers operating business and scientific applications. However,
the use of the term minicomputer has diminished and has
merged with servers.
A minicomputer may also be called a mid-range computer.
10. Information :-
A microcomputer is a computer with a central processing unit
(CPU) as a microprocessor. Designed for individual use, a
microcomputer is smaller than a mainframe or a minicomputer.
The term microcomputer is not as commonly used as it was
during the 1970s-1980s. We now refer to microcomputers as,
simply, computers, or personal computers (PC).
