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.
konrad Zeus was built with elctric relays and eventually vacuum tubes
It used 5200 vacuum tubes.

None. The Harvard Mark 1 ASCC (IBM Automatic Sequence Controlled Calculator) was an electromechanical computer built for Harvard by IBM's Endicott NY facility in 1944. It was constructed from 765,000 components which included switches, relays, motors, rotating shafts, and clutches. It contained no vacuum tubes.The Harvard Mark III ADEC (Aiken Dahlgren Electronic Calculator) was the first computer to use vacuum tubes. It was built at Harvard in 1949 using 5000 vacuum tubes and 1500 crystal diodes, along with electromechanical components. The Harvard Mark IV, built in 1952, was the first fully electronic design.

Vacuum tubes are not important for computer memory any more because we now use transistors. A long time ago however, the Vacuum tubes were important because they had the ability to regulate current flow through them, making them a feasible means for computers.
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.
vacuum tubes are the switching components in the first generation computers to process data. later they were replaced by transistors.
High frequency tubes are still used in radio transmiters, but are built to handle a lot of power. In theory, you could use these to build a computer, but it would be immensely huge and power-hungy. The 4CX250B tube, for example, can handle up to half a gigahertz and smaller tubes could run even faster, i guess.
