Computer Categories The rapid development of science and technology has changed the world. In recent years computers have been used in all fields of human activities: business, industry, education, culture, health care service, economics, politics, mass, media, arts, in everyday life of different people. At present people have to keep step with the time not to be lost in the world of information. So computers are becoming of great importance for most adults and youth. Computers come in many sizes and shapes such as special-purpose, laptop, desktop, minicomputers, supercomputers. Special-purpose computers can perform specific tasks and their operations are limited to the programs built into their microchips. These computers are the basis for electronic calculators and can be found in thousands of electronic products, including digital watches and automobiles. Basically, these computers do the ordinary arithmetic operations such as addition, subtraction, multiplication and division. General-purpose computers are much more powerful because they can accept new sets of instructions. The smallest fully functional computers are called notebook computers. Most of the general-purpose computers known as personal or desktop computers can perform almost 5 million operations per second. Minicomputers are high-speed computers that have greater data manipulating capabilities than personal computers do. These machines are primarily used by larger businesses or by large research and university centers. The speed and power of supercomputers, the highest class of computers, are almost beyond comprehension, and their capabilities are continually being improved. The most complex of these machines can perform nearly 32 billion calculations per second and store 1 billion characters in memory at one time, and can do in one hour what a desktop computer would take 40 years to do. They are used commonly by government agencies and large research centers. Linking together networks of several small computer centers and programming them to use a common language has enabled engineers to create the supercomputer. The aim of this technology is to elaborate a machine that could perform a trillion calculations per second.
