TYPES OF COMPUTER:-
On the basis of size
Microcomputer:-
Microcomputer is also known as personal computer.
It is a general purpose computer which is developed for single user.
It is the smallest in size among all type of computer.
It is the cheapest among all type of computer.
Microprocessor as a CPU, memory, input unit and output unit are used in this type of computer.
Example: Laptop
Desktop
Tablet...........
Microcomputer is also capable of multitasking such as printing. watch the video, browsing, scanning, audio playing etc.
Minicomputer:-
The capabilities of minicomputer is lies between the microcomputer and mainframe computer.
The size of minicomputer is smaller than mainframe computer but larger than the micro computer.
Minicomputer is a multiuser computer , capable of supporting 1 to 200 users at one time.
Minicomputer does not require a controlled operational environment.
It is very fast compared to its size.
Example of minicomputer is -
1. Data General Nova
2.IBM midrange computers
3.CDC 160 A
4.CDC 1700
Mainframe Computer:
The capabilities of mainframe computer is lies between the minicomputer and super computer.
Mainframe Computer is a multiuser computer, capable of supporting from hundreds or thousands users simultaneously.
The mainframe Computer specially requires a large clean room with air conditioner.
This type of computer supports multiple program at a time.
It is very expensive computer.
This type of computer used by large organization to manage bulk data .
It is a multiprocessing computer.
Example of mainframe computer is :-
IBM z Series, system z9 and system z10
Super Computer:
Super computer are the most powerful , biggest and fastest computer among all type of computers.
It can perform trillions of instruction in a second.
It is used to process large amount of data and solve the complicated scientific Problems.
In a supercomputer thousand of user can be connected at the same time and Supercomputer
handles the work of each user.
Supercomputer are mainly used for--
1. Nuclear energy research
2.Aircraft design
3. Automotive design
4.Weather forecasting
5.Quantum mechanism
Example of Super Computer is CRAY 1 and CRAY 2.
TYPES OF COMPUTER
On the basis of data handling-
Analogue Computer:
Analogue Computer are used only to process analog data.
An Analogue Computer is a computer which operates on mathematical variable in the form of continuously changeable entities like mechanical , electrical and hydraulic etc .
These computers works on an analogue signal by using continuous value rather than discrete value.
Example of analogue computer are operational amplifier, mechanical integrators, slide rules , tide predictor etc.
Digital Computer:
Digital computer is a digital system that perform computational task.
The word digital implies that the information in the computer is represented by variable that take a limited no of discrete value.
Digital Computer use the binary no system which has two digit 0 and 1.
The speed of digital computer is more than the analog computer.
Main advantage of digital computer is more accuracy and fast speed.
Example of digital computer are
1.Laptop
2.Desktop
3.IBM PC
4.Calculators
......etc
Hybrid Computer:
Hybrid computer is a combination of analog and digital computer.
The Purpose of hybrid computer is to provide functions and features that can be found on both analog and digital devices.
The construction of hybrid computer in such a way that component make device fast and accurate.
Example of hybrid computer are:
Hycomp 250
Hydac 2400
......etc
