  • Phoenician alphabet is an early alphabet

    • A calculator was the very first sign of an information processor. The popular model of that time was the abacus.
  • Mechanical era was the first start to see connections between our current technology and its ancestors.
  • Mechanical era was time between 1450 and 1840.
  • Electromechanical has some technologies that resemble our modern-day technology.
  • Electromechanical- the time between 1840 and 1940, beginnings of telecommunication.

  • •Second generation – 1959 to 1964
  • Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words.
  • Second Generation Examples: UNIVAC III, RCA 501, Philco Transact S-2000, NCR 300 series, IBM 7030 Stretch, IBM 7070, 7080, 7090 series
  • Third generation – 1965 to 1970
  • Fourth generation – 1971 to Today
  • Third generation is much smaller and cheaper compare to the second-generation computers.
  • Fourth generation computers also saw the development of GUIs, the mouse and handheld devices.
  • •Fifth generation – Today to future
  • Fifth Generation is Based on Artificial Intelligence (AI). Still in development.
