Document Summary

Topic 1: introduction to computer science and computing. Computers cannot be given the quality of smartness because it does not think. It is a simple utensil that provides certain output for input.

Input was still laborious, requiring punch cards and batch jobs. 1965: moore s law the processing power of computer will double every two years : this has held true to today since 1965. 1975: microchip is created, and is used to create the first home computers.
