Types of Computer

TYPES OF COMPUTERS:

Computers are classified into many categories depending upon their size, functioning and processing capabilities.

1. According to how it functions, computers can be classified into three categories:

Analog Compute

            A. Analog: According to the Merriam Webster Dictionary, computers in which continuously variable physical quantities, such as electrical potential, fluid pressure, or mechanical motion, are used to represent (analogously) the quantities in the problem to be solved are called analog computers. 

Digital Computer

            B.Digital: These computers deal with data in the form of numbers. They mainly operate by counting and performing arithmetic & logical operations on numeric data. Such computers are ‘many problems’ oriented.

            

   C. Hybrid:

Hybrid Computer

Digital computers could not deal with very large numbers and so, a computer with characteristics of both analog and digital was created which was known as Hybrid computer

2. According to the size, computers are classified into the following categories:

A. PERSONAL COMPUTER:

The most common types of computer is personal  computer- a personal computer that is designed to sit on  a desk or table. These are the systems you see all  around you, in school, homes, and office.

Personal Computer

 Today’s personal computers are more  powerful than                 those of just a few year’s ago. Not only do  these                     machine enable people to do their jobs with  greater                 ease and efficient, but they can be used to                                  communicate, produce music, edit photographs                         and  videos, etc. the main components of the                               

personal  computer is the system units.

B. MAINFRAME COMPUTER:

Mainframe computer

    Mainframe computers can also process data at very high speeds, but less than thatof super computers. Normally, they are used in banking, airlines and railways etc. for their applications

                    B.  Mini Computer:

  Mini computers provide more power than micro    computers in terms of speed and storage   capacity. They are also less expensive. Their performance is also lower than that of  mainframes.

                    C. MICRO COMPUTER:

 Microcomputers are designed to be used by single user for performing basic operations like educational activities, playing games. These are mainly used in homes, offices, shops, school etc. 

                   D.  SUPER COMPUTER:

Super Computer

A supercomputer is the fastest type of computer. They are employed for specialized applications that require large amounts of mathematical calculations. A supercomputer channels all its power into executing a few programs at great speed, whereas a mainframe uses its power to execute many programs at the same time. These computers are used to solve problems involving quantum mechanical physics, weather forecasting, climate research, molecular modelling such as computing the structures and properties of chemical compounds, simulations, cryptanalysis, and many others.
