Document Summary

A student more than 100 years ago: ford"s first car sold in 1903, wright brothers first powered flight in 1903, typewriters rare, maybe a radio, no telephones, atms, computers or internet, a completely different experience! Y2k (year 2000) problem: result of expensive computer memory in the early days of computing, two-digit to store year values. Knowing something about where technology has been can help us understand where technology is headed. Early computers (1939-1952: complex and expensive, single user, one program at a time, housed at universities, 1947, eniac mark i, 1952, ferut and u of t. 1st digital computers: used in business and government. Ibm 650 (,000 - ,000: add or subtract 16,000 numbers per second. 2nd generation transistor: smaller, easier to maintain, reliable. 3rd generation (mid 1960"s: operating systems, multiprocessing/timesharing, cost millions, mini-computers. Still being used today: fast processing, massive storage. Local area networks (lans: linking many pcs together, shared access to data, printers and peripheral devices.
