Lecture 1 - Introduction to Computers

History of Computers


•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.
Three years later, they introduced the 8080 version, which was capable of running the processing unit of a computer.
•The fifth generation of computers (1990s) offers the development of artificial intelligence, computers based on logical inference and parallel processing, and radical changes in the Internet, as we know it today.
