Mainframe Computers

Mainframe computers are large-size computers with multiple microprocessors for
different tasks. A mainframe computer has large storage capacity with high processing
speed. It can support thousands of users simultaneously. Mainframes can run

multiple operating systems at the same time and provide services to a variety of
users.
They are primarily used by large organisations for

objective-critical applications requiring high volumes
of data processing. Mainframe computers are used
in organisations, such as Internet servers, banks,
airlines, and online shopping sites where many users

need access to shared data and programs at a high
speed without any delay. IBM z10 Cray XMP-24
IBM z10 and Cray XMP-24 are examples of mainframe mainframe mainframe

computers.

Supercomputers

Supercomputers are the fastest
and most powerful type of
computers. A supercomputer

is huge in size, with thousands
of microprocessors working
Fugaku supercomputer Pratyush supercomputer together. It has an extremely
large storage capacity with very high processing speed. It can process trillions of
instructions per second. A supercomputer is a million times faster than the fastest

desktop computer.
Supercomputers are used for specialised applications that require complex numerical

computations, such as train networks, weather forecasting, medical research, code
breaking, and geological exploration.
The world’s fastest supercomputer is Fugaku, developed by Japan, followed by IBM
Summit. Indian scientists have developed supercomputers including Param Yuva II

and Pratyush.
