![]() In terms of storage capacity and speed, it comes between a personal computer and minicomputer. Although it is like a personal computer, it has a more powerful microprocessor and a higher-quality monitor than a microcomputer. For example, NASA uses supercomputers for launching space satellites and monitoring and controlling them for space exploration. The super-computers are task-specific and thus used for specialized applications such as large-scale numerical problems in scientific and engineering disciplines including applications in electronics, petroleum engineering, weather forecasting, medicine, space research and more. They have huge storage capacities and computing speeds and thus can perform millions of instructions per second. Super-computers are the fastest and most expensive computers among all types of computers. For example, Banks, universities, and insurance companies use mainframe computers to store the data of their customers, students, and policyholders, respectively. They are used by large firms and government organizations to run their business operations as they can store and process large amounts of data. It is also a multi-user computer capable of supporting thousands of users simultaneously. For example, the admission department of a University can use a Mini-computer for monitoring the admission process. Individual departments of a company use these computers for specific purposes. So, they are generally used by small businesses and firms. They are multi-user computers designed to support multiple users simultaneously. Mini-computers are also known as "Midrange Computers." They are not designed for a single. Microcomputers are generally designed and developed for general usage like browsing, searching for information, internet, MS Office, social media, etc. ![]() The common examples of microcomputers include laptops, desktop computers, personal digital assistant (PDA), tablets, and smartphones. The first microcomputer was built with 8-bit microprocessor chips. It is a single-user computer which has less speed and storage capacity than the other types. Based on the size, a computer can be divided into five types: Output Device: It enables you to see the output, e.g., monitor.Ĭomputers are divided into different types based on different criteria.Input Device: It allows you to communicate with the computer or to input data, e.g., a keyboard.Storage Device: It permanently stores the data, e.g., hard drive.Motherboard: It is the part that connects all other parts or components of a computer.Memory: It is the primary memory for data transfer between the CPU and storage.Processor: It executes instructions from software and hardware.The basic parts without which a computer cannot work are as follows: Charles Babbage is also known as the father of the computer. It is believed that the Analytical Engine was the first computer which was invented by Charles Babbage in 1837. Whereas, the programs and data are called software. The components of a computer such as machinery that includes wires, transistors, circuits, hard disk are called hardware. ![]() ![]() It also has a memory that stores the data, programs, and result of processing. It works with the help of programs and represents the decimal numbers through a string of binary digits. The term "computer" is derived from the Latin word "computare" which means to calculate.Ī computer is designed to execute applications and provides a variety of solutions through integrated hardware and software components. It can process numerical as well as non-numerical calculations. It renders output just after performing mathematical and logical operations and can save the output for future use. A computer is a programmable electronic device that accepts raw data as input and processes it with a set of instructions (a program) to produce the result as output. ![]()
