Document Summary

Univac i: first commercial general-purpose computer, delivered in 1951, used to forecast the 1952 us presidential election, starting in the 1950s, computers got smaller over time. Grace murray hooper (1906-1992: created first compiler because she was tired of writing machine code by hand. The transistor: (cid:862)the (cid:373)ost i(cid:373)po(cid:396)ta(cid:374)t i(cid:374)ve(cid:374)tio(cid:374) of the 20th (cid:272)e(cid:374)tu(cid:396)y (cid:863, transistor invented by shockley, bardeen & brattain in 1947 at bell labs, replaced vacuum tubes which were bulky. Introduced in 1964: family of computers, with compatible architecture, covering a wide price range, established the standard for mainframes for a decade and beyond. Punch cards: student programmers using the ibm 026 keypuncher, punched card from a fortran program. International business machines: known for commercializing early computing machines (1890s), mainframe computers (1960s), and modern servers (present, also developed methods for process information to improve computing performance, lynn conway, 1964: designed supercomputer architecture on the advanced computing.
