The Digital Revolution

The First Computers

  • electro-mechanical digital computers
  • wire based digital internal storage using PWMC
    • the digital storage was constructed using a mechanical telegraph key as output, a long coiled string, and a pickup transducer to pick up the signal
    • required a refresh circuit
  • no external digital storage

Second Generation Computers

  • mostly electronically digital computers
  • removable magnetic wire coil external storage using PWMC
    • wire coil strung from one spindel to another through a magnetic read/write head

Zero Deliminated Character Code

  • binary stream based digital storage
  • based upon Pulse Width Modulation Code
  • shift character codes switches between lower case, upper case, numbers, punctuation, and codes

Third Generation Computers

  • transistor based digital computers

Fourth Generation Computers

  • integrated circuit based digital computers

Fifth Generation Computers and Beyond

Stagnation and The Zeron
