Computers can be classified into various categories depending on their size, storage

capacity, speed and type of experience in personal computing.

Supercomputers

Multi-user, multiprocessor large
computer of very high efficiency and
storing capacity is called supercomputer

able to solve very difficult and complex
problem within a nano seconds. Today’s
supercomputers consist of thousands of
processors that are able to perform

billions and trillions of calculations per
second. Supercomputers
