General Knowledge for computer:-

Science has discovered many wonders and computer. It is ultra modern electronic device for

Storing and analyzing information fed into it. It has no capacity to do anything by itself

it works on the basis of commands given by the operator.

Computer was not invented over Night it took long time and hard lab our to invent computer

Many votaries of science .first of all Pascal invented the theory of "digital calculating system"

in 1642 though his attempts were not crowned with success. He initiated the research which hastened/paved

the way to invention of computer. Finally Mr.Haward Akin. an American scientist invented such

A machine in 1937 that could do difficult sums. So the credit for the invention of modern

Computer goes to . Howard akin after seven years electric computer used in Harvard University

In 1944 after that many other computer have been invented such as EDSAC in 1945 etc.

How to work a Computer:-

 We kwon that Computer is a Programmable Electronic Machine

A Computer Receive data that means Input Then Store and processing at last Output.

   

Generation of Computer (Computer has five Generations):-

First Generation of Computer in 1940-1956. charles Babbage was the first to conceptualize and design a fully programmable mechanical computer  his name is analytical engine his device is not completed I think that ENIAC was first electronic calculator. Design

 this time Computer has Vacuum Tubes and Computer size of a large room so it is not moveable .The first electronic computers were developed in the mid-20th century 1940–1945.this time input device has punched card and magnetic drums for memory of Computer. First generation computers relied on machine language. It operate has very difficult and they could only solve one problem at a time. the BendixG-15 and the IBM 650, used magnetic drums as their main memory. IBM 650 was a first-generation computer.

Second Generation of Computer

Second Generation of Computer in 1956.this time smaller than vacuum tubes. Assembly language was the second generation of computer language. Assembly language easy then machine language
