Document Summary
Cpsc 121 lecture #38 computer history & a working computer. Topics included: intro to computer history, a working computer. The start of computing (continued: after babbage, konrad zuse made the first electromechanical computer in 1941. It was destroyed in wwii: 1946: the eniac was the first fully electronic computer, used decimal arithmetic, needed manual physical reprogramming, fully female programming team, punched cards held programs and data, similar to jacquard"s looms. Cpsc classes: cpsc 121 is about gates and simple circuitry, cpsc 213 is about implementing constructs (e. g. if, while loops) made using the basics learned in cpsc 121, cpsc 313 is about making efficient computers and programs. Involves a cpu (central processing unit) decides what instructions are needed and executes them: has two units, arithmetic unit. In charge of arithmetic and logical operations: control unit, appears to execute its instructions sequentially, but in reality multiple instructions are being executed at each.
