The first evolution of computers did not have monitors or memory. The abacus, the adding machine was invented in Babylon in 500 B.C. It was used to count and keep track of money and other numerical things. Then famous mathematicians invented calculators using gears and wheels.
In 1833, Charles Babbage invented all the parts the modern computer uses, but it wasn't until 120 years later that the first modern computers were invented. These first computers were huge and took up a whole room. Since we have learned so much about computers, now let us see how computers were invented. The Evolution of Computers is defined in terms of five generations. Let us take a look of them:
First Generation Computer (1940-1956)
Second Generation Computer (1957-1963)
Third Generation Computer (1964-1971)
Fourth Generation Computer (1972 onward)
Fifth Generation Computer (Present and Future)
