Document Summary

Origins of digital computers: abacus: aid computation, finger powered calculator. Schickard mechanical calculation: pascal decimal calculator (turning dials, leibniz (cid:498)leibniz wheel(cid:499) for multiplication = full, analytic engine never built. Loom: punch cards to define complex patterns. Babbage: used method of differences to calculate, difference engine featured calculator polynomials, automated computation of tables & printing, legacy: first digital computing device (ahead of its time) World"s first programmer: lovelace (female) wrote programs for difference, boolean algebra laid foundations of digital. Slide rule invented by oughtred: replaced by electronic calculator around 1974. Part ii birth of electronic computers 1930 to. Introduced application of boolean logic in creating digital computing machines. Turing: broke code for enigma machine (cid:498)a mathematical theory of communication(cid:499, proposed abstract for defining computability the, devised the (cid:498)turing test(cid:499) for artificial intelligence, atanasoff-berry computer (abc): lacked (cid:498)stored program(cid:499, konrad zuse, germany: z1 toz4 computers. Ibm automatic sequence controlled calculator (ascc) installed at harvard university.
