HISTORY OF COMPUTER
Computer is an electronic device which accept data as input through some Input deices, process that data according to the stored program and give us the result as output through some output devices.
Compute mean compute which is “to calculate". there fore the computer is a machine process or more faster tan a human beingSo there it need a man for the works.the calculation process is start from the 600 BC and name is abacusWhich is use for the calculation ..> The abacus also name “sorobran”.and it was introduce by cranmer.
In earlier 17th century the famous logarithm idea was developed john Napier the Scottish mathematician, he created the table calculation logrithem

In 1642 a scientest of france, name Blaise Pascal was fist devloped the mechanical calculator or calculating machine. And its name is pascalene .it was first calculator in the world.

Gotfried von1671 German mathematician Gottfried developed first calculator for the multiplication as well as for the other arithmetic calculation. it is similar to the Pascal calculating machine it use through the gear system.
Punch board systemA French engineer Josef Marie invented a punch board systemfor power looms. It was use to design for the clothing specificweaving patern for the cloths automaticalley later this idea wasused for calculating process.

Calculating device Charles Xavier
Charles XavierArthometer
This mashine use for the arthematic calculation such as multiplication ,division adition and subtractioin .
Calculating machine by Charles babbgeMathmatic professor in cambriage university develop a special type of calculator , it was callled“differnce machine “which was powered by steam for mathematical calculation.babbege also called the father of computer.
Charles Babbage Charles difference machine
Charles Babbage analytical engine
It wqs the first programmable computer which work througthe prorame.it was avrege speed to perform the 60 adition in Per min.
Lady Ada AugustaIt was the student of Charles Babbage work with charles in designing the “analytical engine “ she was the first programable women which put the programeIn the analitical engine
1) Punch card by herman hollerth(1860 to 1929). He was introduce the punch board system and introduce the punch card as input system. he developed the first electro mechanical punch card
2) Atnaff berry computer. He was invented the electrial machine to solve the mathematical problem. It was called atnaff berry computer or ABC.this working machine was complete in alg1942.
3) Boolean algebra . He was introduced the logic circuit inside the computer .
4) Mark_1 or ASCC. It stand for ( automatic sequence controlled calculator ) it was work under the controlled of the punched board .the instruction give through the punched board. this machine is 50 feet long 8 feet high 30 feet width. It was basically an electro magnetic device. In which the electronic and mechanical component were used.
5) ENAIC (1943 to 1946). It stand for electronic numerical integral and calcutor . It was the first electronic computer. it was developed at moore school of engineering university in 1943. it contain 18000 vacuum tube and occupied more than 1500 square feet with of weight of 30 tons.
6) UNIVAC (1951). I stand for the ( universal automatic computer)it wsathe first digital computer. The program and data were feed through the magnetic tape.
6) IBM (1952). IBM corporation introduce the new system which is 701 commercial computer . In 1953 produce 650 and 1000 no's of computer.
