CLASS OF COMPUTER



Our world is a symphony of infinite variations. Long before digital computers existed engineers built models to simulate those real world nuances.
Analogue computers continued this tradition, using mechanical motion or the flow of electricity to model problems and generate answers quickly.
Computers use analog and digital signals in order to process raw data into useful information. Whereas analog computer are fast at processing, digital computer give the most accurate information.
We have the following three types of computer: Analogue, Digital and Hybrid…



Analogue Computer
Analogue Computer Process analogue Data. Analogue data is data that varies smoothly or in a continuous fashion. An analog computer uses the continuously-changeable aspects of physical phenomena such as electrical, Mechanical, or hydraulic quantities to model the problem being solved.

A good example of an analogue device is an analogue clock. An analogue clock shows the time variation with its hand that glides smoothly to the next value. The change from one digital to the next is continuous. It doesn’t get to the next value by jumping but by a continuous movement.
An analog signal would look like a series of peaks and valleys, drawn with seemingly no meaning. Your voice, live music and sounds are analog signals.

Uses of analog Computer
Analog devices were/ are used for specific industrial assignments to measure parameters that vary continuously..
The first major analog computers were used to design and test various kinds of aircraft, ICBM(Intercontinental ballistic missiles), and in numerous industrial installations. Scientists in the early years turned to these system to bring their ideas to life…
Example of analog computers include the planimeter, the nomogram, car speedometer, tyre pressure gauge, thermometer, mechanical integrators, slide rule, tide predictors, oscilloscope used to measure electronic instrument voltage against time….

The differences between analogue and digital computers

The major difference between digital and analog computers is the manner in which they handle data. While digital computers use binary language in order to accurately effect computation, analog computers handle continuous data such as voltage changes and temperature fluctuations to output computation.
An analog display uses some form of pointer which indicates a value depending on its position or angle on a scale as can be seen on traditional watches and clocks, weighing scales, speedometers and old style moving coil or moving iron voltmeters and ammeters..
A digital display indicates the value of a parameter directly by actually showing a number. This number can be produced on an LED, LCD or Nixie tube display..

Digital Computers

Digital computers process digital data.. They represent data in digital format often binary form and perform operations on data using mathematical manipulation. Digital computers have devices to store using mathematical manipulation. Digital computers have devices to store information, some method for input and output of data and components that allow mathematical operations to be performed on stored data…

Examples of digital computers include mainframe, super, mini and Micro computers. Since most computers operate under binary form, almost every computer from the desktop PC to the smart phone could be considered to be digital. Digital computers are capable of delivering more accurate data because they manipulate logical and arithmetic operations like multiplication, addition, subtraction and division. They are versatile and handle a variety of productivity functions and applications…

Hybrid Computer
Hybrid computers are computers designed to process both digital and analogue data. Hybrid computers combine the features of analog and digital computer. The digital component normally serves as the controller and provides logical and numerical operations, while the analog component often servers as a solver of differential equations and other mathematically complex equations…..
Examples of hybrid computers include medical devices such as ECG,EKG and EEG machines that are used to monitor patients heart beat, breathing oxygen level, blood pressure, pulse etc…… these machines take in an analog signal and convert it into digital format….
