Types of computer
Types of computer
In this article we learn about the types of the computer? and which is best for you? as per your requirement respectively changes the types of computer,how they classified?The basic four types of computer:
 |
| TYPES OF COMPUTER |
1.Super computer :-
First supercomputer was invented in 1920 in the united states with the IBM tabulator in Columbia.
Supercomputer is a high performance computer compared to the general computer.supercomputer measures in the floating points operations per second(FLOPS). instead of millions instructions per second in 2017.

2.Main Frame Computer :-
They are larger in size and more power full in processing.
In Main frame computers used the high-end commercial machine
from less power full unit.
Main frame computers established in the year of 1960s and they used for the SERVERS.
Computing is very high in main frame computer.It is very high costly maintenance and take more space for assembling.
It's mainly used for store the big data storage,and fastly processing for the data.
More users handled at a time in the main frame computers.
In main frame computers use the UNIX operating system and in the latest models of main frame computer use the LINUX.
This operating system is best solution from the hacker.Hacker not accessed the LINUX and UNIX easily data are safely store in the computer.
Main frame computers are 24 hours are in the working condition, and they backup and restore system is working at every time. Continuous working of mainframe they generate the heat in big quantity. for best performance there cooling system is working continuous 24 hours and worked at the high rate of processing.
Main frame computers are larger in size and have many terminals connected with a network.

3.Mini Computer :-
A computer with a medium power as more than microcomputer but less than main frame computers.
First PDP-8 launched in mid of 1965 there price is US $ 18000.
Celeron 1007/1037u is success in the banking and airline.
In 1970s Survey of The New York Times suggested a consensus definition of mini computer as a machine costly less than US $ 25,000 with an input and output device.
It's running at high level programming of eg. FORTRAN , BASIC.
Mostly use for the business and scientific applications.

LIST OF SOME MINI COMPUTERS :-
- CONTROL DATA'S CDC 160A and CDC1700
- DEC PDP and VAX series
- DATA GENERAL NOVA
- Hewlett-Packard HP 3000 Series
- IBM Mid Range Computers
4.MICRO COMPUTER :-
A small computer that contains a microprocessor as it's central processing unit(CPU).
Micro computer popular in 1970s and 1980s with power full micro processor.its based on the input and output device eg. keyboard,screen ,etc.
Microcomputers are cheaper than mini computer and compatible to use as a beginner level of user.easily to operate and mostly use as a commercial,business and home based or personal use (personal computer).
In January 1975 first microprocessor of Intel 8080 chip use in the ALTAIR 8800 chip. BASIC programing system used in the Altair.
64 KB of RAM.
10 Mb of Hard Disk.
8 Inch floppy disk with 180-360 Kb
