Since the advent of the first computer different types and sizes of computers are offering different services. Computers can be as big as occupying a large building and as small as a laptop or a microcontroller in mobile & embedded systems.The four basic types of computers are. 1. Super computer 2. Mainframe Computer 3. Minicomputer 4. Microcomputer See Also: What is a Computer?
Supercomputer

The most powerful computers in terms of performance and data processing are the supercomputers. These are specialized and task specific computers used by large organizations. These computers are used for research and exploration purposes, like NASA uses supercomputers for launching space shuttles, controlling them and for space exploration purpose.
The supercomputers are very expensive and very large in size. It can be accommodated in large air-conditioned rooms; some super computers can span an entire building.
In 1964, Seymour cray designed the first supercomptuer "CDC 6600".
Uses of Supercomputer
In Pakistan and other countries Supercomputers are used by Educational Institutes like NUST (Pakistan) for research purposes. Pakistan Atomic Energy commission & Heavy Industry Taxila uses supercomputers for Research purposes.
Space Exploration
Supercomputers are used to study the origin of the universe, the dark-matters. For these studies scientist use IBM’s powerful supercomputer “Roadrunner” at National Laboratory Los Alamos.
Earthquake

    A supercomputer does everything a personal computer can do, except far more efficiently and with a significant amount more power. The Columbia has 4608 cores on all 4 nodes in comparison to my computer’s 4 cores, except it was built in 2004 and mine was built in 2012. It had 800 TB of storage capacity as well as 2 GB of RAM per core (4608 total). If they rebuilt this supercomputer today using state-of-the-art technology, it would be capable of things that can’t yet be imagined.…

    Supercomputer is a broad term for one of the fastest computers currently available. Supercomputers are very expensive and are employed for specialized applications that require immense amounts of mathematical calculations (number crunching). For example, weather forecasting requires a supercomputer. Other uses of supercomputers scientific simulations, (animated) graphics, fluid dynamic calculations, nuclear energy research, electronic design, and analysis of geological data (e.g. in petrochemical prospecting). Perhaps the best known supercomputer manufacturer is Cray Research.…

    In the future computers will be used to create bigger and even more sophisticated computers. The prospects for this are quite alarming. They will be so complex that no individual could hope to understand how they work. They will bring a lot of benefits but they will also increase the potential for unimaginable chaos. They will, for example, be able to fly planes and they will be able to co ordinate the movements of several planes in the vicinity of an airport. Providing all the computers are working correctly nothing can go wrong. If one small program fails disaster.…

    Some of the major parts of a personal computer (or PC) include the motherboard, CPU, memory (or RAM), hard drive, and video card. While personal computers are by far the most common type of computers today, there are several other types of computers. For example, a "minicomputer" is a powerful computer that can support many users at once. A "mainframe" is a large, high-powered computer that can perform billions of calculations from multiple sources at one time. Finally, a "supercomputer" is a machine that can process billions of instructions a second and is used to calculate extremely complex calculations.…
