01.Supercomputers.

02.Mainframecomputers

03.Minicomputers

04.Microcomputers

Super Computers

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.

Mainframe Computers

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

Mini Computers

A minicomputer, or colloquially mini, is a class of smaller general purpose computers that developed in the mid-1960s and sold for much less than mainframe and mid-size computers from IBM and its direct competitors.

Micro Computers

A microcomputer is a small, relatively inexpensive computer having a central processing unit made out of a microprocessor.
