2 1946 - ENIAC - Eckart & Mauchly - caculate firing tables and trajectories Modern Day Evolution of the Computer - fast computations and repetitive work - based on 1/0, on/off, holding and releasing a charge - voltage travels along a copper wire 1st gen - used vaccuum tubes - vaccuum tubes used in early TVs 2nd gen - '59 - '65 - transistor, replaced vaccuum tubes - the components are smaller - more components and faster - PDP-8 - 1st minicomputer 3rd gen - integrated circuits - even smaller - timesharing - late 60s - early 70s - IBM 360, 360 = all around computing - timesharing vs. batch - effects of timesharing
