Classification of Computer

Classification of Computer:

Types of Computers

1. Digital computer –Digital computer is the most commonly used type of computer and is used to process information with quantities using digits, usually using the binary number system. Ex – MacBook.
2. Analog Computer – A computer that operates with numbers represented by directly measurable quantities (as voltages or rotations) — compare digital computer, hybrid computer.
3. Hybrid Computer – A computer that combines the characteristics of a digital computer and an analog computer by its capacity to accept input and provide output in either digital or analog form and to process information digitally.

Classification on size

1. Mainframe computer – A mainframe computer is a very large computer capable of handling and processing very large amounts of data quickly. They are used by large institutions, such as government agencies and large corporations.
2. Mini Computer – a computer with processing and storage capabilities smaller than those of a mainframe but larger than those of a microcomputer.
3. Micro computer – A microcomputer is a complete computer on a smaller scale and is generally a synonym for the more common term, personal computer or PC , a computer designed for an individual.
4. Personal computer – A personal computer (PC) is a small, relatively inexpensive computer designed for an individual user. In price, All are based on the microprocessor technology that enables manufacturers to put an entire CPU on one chip.
5. Supercomputer – The fastest type of computer. Supercomputers are very expensive and are employed for specialized applications that require immense amounts of calculations.
