Slide Notes
First generation (1940s) computers used vacuum tubes to conduct electricity.
Second generation (1950s) - transistors replaced tubes, integrated circuits in 1970s (the third generation).
Fourth generation: large-scale, integrated circuit chips. 1971, Intel introduced the 4004 microprocessor.
The microprocessor chip is a central processing unit, the brains of the computer, built on a single chip.
