Types of Computers

Types of computers

Three Types

• Analog Computers
• Digital Computers
• Hybrid Computers

Analog Computers

• Analog computers store and process data in a continuous from of physical quantities such as electrical, mechanical, or hydraulic quantities to model the problem being solved.
• As mechanical computers used in World War Second II for controlling gun fire.
• An analog computers is a form of computer that uses the continuously changeable aspects
• Analog computers are also used in science and industry.
• Analog computers deal with measure data.

Ex:

• Thermometer because it measures the length of a mercury column, which varies continuously.
• Analog Clock
• Car Speedometer

Digital Computers

• A digital computer is an electronic computing machine that uses the binary digits(bits) 0 and 1 to represent all forms of information internally in digital form.
• Every computer has a set of instructions that define the basic functions it can perform.
• Sequences of these instructions constitute machine-language (Low level language in the form of 0’s and 1’s )programs that can be stored in the computers.

Ex:

• Calculator (a small computer)
• Digital clock, Digital watches
• Weighing machines
• Consumer electronic equipment (such as microwave oven )
• Automobiles
• Mini, Micro, Mainframe and super computers.

Hybrid Computers

Hybrid computers are computers that exhibit features of analog computers and Digital computers. The digital component normally serves as the controller and provides logical and numerical operations, while the analog component often serves as a solver of differential equations and other mathematically complex equations.

Hybrid computers are computers that exhibit features of analog computers and Digital computers.

Ex:

• Ultrasound Machine
• Electrocardiogram Machine
• Gasoline Station
