FIRST GENERATION
first generation computers
vacuum tubes
Vacuum tubes were first replaced by transistors, and later by integrated circuits.
no, first generation computers used vacuum tubes.
First generation computers.
first generation
Oh yes - and for several generations after that. ENIAC, the first mainframe computer, had to be kept in a room with very heavy air conditioning (about 60 degrees) because of the heat generated by all the vacuum tubes.
By most definitions, first generation computers were the ones built with vacuum tubes.
vacuum tubes are the switching components in the first generation computers to process data. later they were replaced by transistors.
ENIAC was the first digital general purpose computer, built in 1946, and with 17,468 vacuum tubes. The Illiac I, the first computer built and owned by a US educational institution, had 2800 vacuum tubes. The IBM 604 had about 2000 vacuum tubes.
Machines using vacuum tubes as their active elements.
