Supercomputers, also known as MONSTER, stand as the pinnacle of computing power, boasting unparalleled size, speed, and cost. Valued at several million dollars, these machines operate at speeds ranging from 600 million to 900 million instructions per second (MIP). Supercomputers find utility in various scientific endeavours, including weather forecasting and exploration, handling complex calculations exemplified by systems like CRAY and X-MP.

 

Mainframe Computers

Mainframe computers, distinguished by their substantial price, large internal memory, and enhanced speed, come equipped with a range of peripheral devices such as printers and plotters. Unlike smaller computers, they require specialized environments with controlled dust, temperature, and humidity. Mainframes find application in large institutions like banks and airports, with notable examples including IBM 360/370 and NCR-V 8800.

 

Mini Computers

Developed in the 1970s for specialized tasks, minicomputers are smaller, less powerful, and more affordable than mainframes. Known for their ease of installation and operation, examples of minicomputers include PDP II, VAX 750/6000, NCR 9300, DEC, and HP 3000.

 

Micro Computers

Microcomputers, driven by microprocessor-based central processing units (CPUs), reign as the most popular computers today. Despite their limited capabilities compared to minicomputers and mainframes, microcomputers, or Personal Computers (PCs), offer simplicity and convenience. Their widespread use can be attributed to their affordability, small size, adaptability to any environment, and ease of use.
