History Of Computer

What is the compute  



Compute the amount of a number it is called computer. A computer is an electronic machine that can be programmed to accept data (input), process it into useful information (output), and store it in a storage media for future use. A device that computes, especially a programmable electronic machine that performs high-speed mathematical or logical operations or that assembles, stores, correlates, or otherwise processes information.

Abacus •

The abacus, a simple counting aid, may have been invented in Babylonia (now Iraq) in the fourth century B.C.

•

This device allows users to make computations using a system of sliding beads arranged on a rack.

Analytical Engine 







The system was started by kick the boot. So this process is called booting process. This computer is also called Pre Electrically engine. This computer was invent by Charles Babbage. Charles Babbage is the father of computers.

First Electrically Engine 

This computer was invented by Dr. Herman Hollerith.

Digital Computer 



This computer is called ABC (Atanasoff Berry Computer). This computer was invent by John Vincent Atanasoff and his student Clifford Berry.

ENIAC  



This computer invented by John W. Mauchley. This computer used for U.S. Army and Navy for bombing and firing. 30 x 50 feet space and over 30 tons

Colossus 



This computer also used for army and navy for bombing and firing. This computer is invented by Max Newman.

Type of modern computers 1. 2. 3. 4.

Micro Computer Mini Computer Main Frame Computer Supper Computer

Micro Computer 



Desk top computer is called micro computer. This computer is used in playing games, moves, songs and create data. E.g. Desktop and Laptop.

Mini Computer  





Mini computer is also called Mid Ring Server. Mini computer is a centralize server of that 100 peoples. There are mutable processing unit in a single chip out off each processing unit can do sprit kind of word. It is improve religion of micro computer. E.g.. Roux magnum CDC 60 etc.

Main Frame Computer 



This computer is centralize server of that 1000 peoples at a time. This computer is big and very heavy.

Supper Computer 

This computer is used for chemical analysis and weather information.

Generations Of Computers     

(1). (2). (3). (4). (5).

First Generation Second Generation Third Generation Fourth Generation Fifth Generation

First Generation (1942 - 1954)

 2.

3.  5. 6. 7.

Advantages:These computer were the fastest calculating device. They perform there computation in mini second. Disadvantages:They were large in size. Slow in speed. Its generate more heat.

Second Generation (1955 - 1964)

 2.

3. 4.  6. 7. 8.

Advantages:They are small in size as compared to first generation computer. They generate less amount of heat. They composed very little power. Disadvantages:Air conditioning were required. Constant maintaining was required. Product was difficult and costly.

Third Generation (1965 - 1975)

 2.

3. 4.  6.

Advantages:They are smaller in size as compared previous generation computer. They are more reliable. They generated less amount of heat. Disadvantages:While creating IC chip highly

Fourth Generation (1975 - 1989)

 2. 3.

4.  6.

Advantages:They are small in size. They generated negligible amount of heat. They were very much reliable. Disadvantages:Highly sophisticated technology is required for the many future are large scull integrate on (LSI) chip.

Fifth Generation (1989 - Present)



Till fourth generation computer the main stress was on hardware technology though. These computer are factor more accurate, reliable, small in size and cheapest and still they back their own thinking power. The fifth generation to make division like human being it will be more eyeful in knowledge processing rather

I/O Ports of the Mother Boards 1):- PS/2 Port = 6 Pins Green for mouse and Purple for keyboard. 2):- Serial (Comport) = DB 9 Pins male connector external modem and serial mouse. 3):- VGA Port = DB 15 Pin female connector for a color monitor. 4):- Parallel = DB 25 Pin female connector for a DMP printer and scanner. 5):- U.S.B. Port = DB 4 Pin for any U.S.B. devise connector. 6):- LAN Port = R.J. 45 connector for networking. 7):- Sound Port = 3 Jack, Green for Spicer, Blue for Mice, Orange for Headphone. 8):- Game Port or Midi Port or Joy Stick Port

Peripheral of the Computer It is two types. 1):- Internal 2):- External 

Internal Peripherals Input Devise = Scanner, keyboard, mouse, CD drive, sound card, digital camera.  Output Devise = Monitor, printer, CD R/W, speakers, sound card.  Processing Devise = CPU, RAM, BIOS, motherboard, microprocessor.  Storage Devise = it is two types. A):- Magnetic Storage Devise = HDD, FDD, Tape Drive. B):- Optical Storage Devise = CDD, DVD. 

External Peripherals    

Printer Scanner External modem speaker
