History of Computing

This lesson is part of A.I. · All levels

Summary

The history of computers records four great generations based on its main technology: vacuum tubes, transistors, integrated circuits, to microprocessors. Each generation produced smaller, faster, more energy-efficient, and cheaper computers. It's this development that has brought computers from a big room into a device in our pocket.

Key points

Generation 1: tube vacuum, room size and heat.
Generation 2: Transistors, smaller, more energy efficient, and more reliable.
Generation 3: integrated circuits (IC) that combine many components.
Generation 4: microprocessors that allow PCs and personal devices.
The trend is smaller, faster, cheaper, and more energy efficient.
