TOPIC: Classification By Generation

The following are the five generations of computers.

First Generation of Computers (1942-1955)

When computers were first made, they were large and costly. They gave out heat when used. They were also slow in making calculations and could only store very few items of information. They also needed a lot of electricity before they could be used.

Second Generation Computers (1955-1964)

Soon, the large, costly and slow computers were no longer used by many people. New computers which were cheaper and smaller than the first ones had been made. These were the second generation computers. These new computers stored many more items of information than the earlier computers. They also used less electricity. These second-generation computers worked faster than the first-generation computers.

Third Generation Computers (1964-1975)
