Document Summary
Mainframe systems in large businesses (required a lot of data processing, such as banking and insurance) & with government. Transistors required less power and less space than vacuum tubes. (vacuums required for example ac so it would"t catch re) Transistors made the environment easy to have a computer. Univac predicted election, eisenhower won and the computer was right but people did"t think that was right so they changed the computers prediction for the public view and to save their reputation. Ibm"s war time experience becomes useful when making machines for the public. Upgrade models and keep the same program. (stay within the computer family) Time sharing = multiple users on the same computer. (ibm didn"t make them for that) Automatic example = automobiles blending mechanization and computing. Thanks to military research = aircraft simulator (whirlwind) funded by government. Shifted from simulated pilots to a air defence system. (cold war, atomic bomb.
