The first generation (1940–1956) used vacuum tubes. Examples are ENIAC, UNIVAC I, IBM 650, IBM 701 etc. The early relay computers could also be included here (Z3, Harvard Mark 1).
The second generation (1956-1963) used discrete transistors (but not integrated circuits). Examples are the IBM 7090 and 7094, UNIVAC 1107, PDP-1 and 8, etc.
Both the first and second generation used punched cards for input and output, and magnetic tape drives for mass storage. First generation used electrostatic memory, mercury delay lines and core memory for local storage; second generation used just core memory.
