Document Summary

Sc/eecs 1520 computer use: fundamentals (fall 2017) Part i ancient history: up to 1930. Computing history: abacus earliest computing device designed to aid numeric computation, wilhelm schickard (1592-1635) mechanical calculator, blaise pascal (1623-1662) decimal calculator could add and subtract by turning, g. w. f. Leibniz (1646-1716) stepped reckoner full-featured calculator: joseph marie jacquard (1801) used punch cards to define complex patterns. Cards were later used to code computer programs: charles babbage (1791 1871) designed two calculating machines 1) difference engine . Automated both the computation of tables and their printing, used the method of differences to calculate polynomials: analytical engine was inspired by the punch cards but given the tech at the time it was never built. Designed the first general-purpose digital computing device but his ideas were ahead of his time: george boole (1815-1864) boolean algebra laid logical foundations of digital computing circuitry. Part ii birth of the electronic computer (1930-1951)
