Introduction : 

Introduction A computer is a machine that manipulates data according to a set of instructions. The first electronic computers were developed in the mid-20th century (1940–1945). These were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).

Types of computer : 

Types of computer

Analog computer : 

Analog computer Analog computer measures and answer the questions by the method of “HOW MUCH”. The input data is not a number infect a physical quantity like tem, pressure, speed, velocity. Signals are continuous of (0 to 10 V) Accuracy 1% Approximately High speed Output is continuous Time is wasted in transmission time

Hybrid Computer : 

Hybrid Computer The combination of features of analog and digital computer is called Hybrid computer. The main example are central national defense and passenger flight radar system. They are also used to control robots.

Digital Computers : 

Digital Computers Digital computer counts and answer the questions by the method of “HOW Many”. The input data is represented by a number. These are used for the logical and arithmetic operations. Signals are two level of (0 V or 5 V) Accuracy unlimited low speed sequential as well as parallel processing Output is continuous but obtain when computation is completed.

Micro Computer : 

Micro Computer Micro computer are the smallest computer system. There size range from calculator to desktop size. Its CPU is microprocessor. It also known as Grand child Computer. Application : - personal computer, Multi user system, offices.

Mini Computer : 

Mini Computer These are also small general purpose system. They are generally more powerful and most useful as compared to micro computer. Mini computer are also known as mid range computer or Child computer. Application :- Departmental systems, Network Servers, work group system.

Main Frame Computer : 

Main Frame Computer Mainframe computers are those computers that offer faster processing and grater storage area. The word “main frame” comes from the metal frames. It is also known as Father computer. Application – Host computer, Central data base server.

Super Computer : 

Super Computer Super computer are those computer which are designed for scientific job like whether forecasting and artificial intelligence etc. They are fastest and expensive. A super computer contains a number of CPU which operate in parallel to make it faster. It also known as grand father computer. Application – whether forecasting, weapons research and development.
