Categories of Computers
There are three major ways to categories Computers.
Size & Speed: By size and speed computers divided into 4 classification, depending upon the capacity and speed of processing the data
Working Principal: By working behaviors computers divided into 3 types, depending upon the data and how computers process the data
Technology: By technology computers divided into 5 generation, each generation has different hardware manufacturing technology.
Classification of Computers (By Size & speed)
Micro or Personal Computers
A personal computer (PC) is a computer that can perform all of its inputs, processing, outputs and storage activities by itself. A personal computer contains a processor, memory, and one or more input, output, and storage device.
Mini or Midrange Computers
It is larger and more powerful computers than personal computers. It can execute five billion instructions per second. It generally consists of two or more processors. It is more reliable than desktop computer. Mini computers were introduced in 1960s. Mini computers are used in small companies to provide centralized store of information.
Mainframe Computers
A mainframe is a large computer in term of price, power and speed. It consists of multiple processors. It is specially designed to perform multiple intensive tasks for multiple users simultaneously. It was introduced in 1970s. A typical mainframe computer can execute 16 million instructions per second.
It is used in large organizations, such as banks, Universities and Multinational companies etc.
Super Computers
Super computer is the biggest in size, most expensive in price and powerful than any other computer. It can process trillions of instructions in one second. The modern super computer consists of thousands of microprocessors.
Super computers are used in weather forecasting, weapon design, preparing models of chemical and biological system, mapping the surface of the planets and studying the neural network of the brain.
