What is Computer Generation?

In simple language, computer generations explain which main technology computers were based on during different time periods. For example, first generation computers were based on vacuum tubes. In the second generation, transistors were used. In the third generation, integrated circuits were used. In the fourth generation, microprocessors were introduced and the fifth generation focuses on artificial intelligence.

1. First GenerationVacuum tube based computers. They were very large in size, slow, costly and produced a lot of heat.

2. Second GenerationTransistor based computers. They were faster, more reliable and smaller than first generation computers.

3. Third GenerationIntegrated Circuit (IC) based computers. Size became smaller and speed and efficiency improved further.

4. Fourth and Fifth GenerationFourth generation is microprocessor based. Fifth generation is considered related to AI and advanced processing.
