I did't find anywhere that it was when I researched it.
Over 99% of computers built from 1940 to 1958 used vacuum tubes as their active elements for: logic, power supply, memory sense/drive, etc. circuits. Other computers at this time were electromechanical, magnetic, and a small number of experimental transistor computers were built.
From 1959 to about 1965 most computers used transistors as their active elements for: logic, power supply, memory sense/drive, etc. circuits. A small number off computers at this time were magnetic or used primitive monolithic ICs.
From 1964 on more and more computers used ICs, of progressively increasing density.
The first programmable computer was the electro-mechanical Z1 in 1936. The first digital computer was Atanasoff-Berry Computer (ABC) in 1937 (using vacuum tubes) and the first electric programmable computer was Colossus in 1943.
Transistors (which replaced vacuum tubes) did not exist until 1947.
The vacuum tube can be used as any of the following:
- amplifier
- switch
- rectifier
- logic gate
- display
- dram
- light sensor
- voltage/current regulator
- etc., etc.
For the same reason they used vacuum tubes for radios, TVs, phonographs, etc. at the same time: they were the only electronic components available that could amplify signals. In the late 1950s there was a brief period where magnetic amplifiers were perfected and a few computers were built using them, but the transistor quickly became faster, smaller, and lower power than either vacuum tubes or magnetic amplifiers; so there was no computer generation based on magnetic amplifiers. Transistors were introduced into radios, TVs, phonographs, etc. somewhat later than computers because the early transistors were too expensive for cheap consumer products.

What generation was vacuum tubes used?
first generation computers
What was the 5th generation of computers?
First generation (1940-1956) Vaccum Tubes Second Generation(1956-1963)Transistors Third Generation(1964-1971)Integrated circuits Fourth Generation(1971-present)Microprocessors We already know about some of the early computers - ENIAC , EDVAC , EDSAC , UNIVAC I and IBM . These machines and others of their time used thousands of vacuum tubes . A vacuum tube was a fragile glass device , which used filaments as a source of electronics and could control and amplify electronic signals . It was the only high-speed electronic switching device available in those days . These vacuum tube computers could perform computations in milliseconds and were referred to as first generation computers.
What was the role of the valves in Colossus?
the first electronic computers were built before the invention of the transistor or integrated circuit chip. They used vacuum tubes for the processing and temporary memory. In Britain those tubes were called valves.
What do today's computers use for vacuum tubes?
Billions of microscopic transistors integrated onto individual chips of Silicon. And one computer may have a few hundred of these chips doing different things. Vacuum tube computers, even the largest, rarely had more than 10,000 tubes.
How many vacuum tubes are in the Univac I computer?
It used 5200 vacuum tubes.
Who is the first generation of computers?
vacuum tubes
What generation computers used vacuum tubes?
FIRST GENERATION
What generation was vacuum tubes used?
first generation computers
What computers will used vacuum tubes?
First generation computers.
What are first generation computers?
By most definitions, first generation computers were the ones built with vacuum tubes.
Was a Microcomputer part of the first generation?
no, first generation computers used vacuum tubes.
Vacuum tubes microprocessor based computers are?
first generation
What was the first generations of computers?
The first generation of electronic computers were those implemented using vacuum tubes.
Why were the ABC and ENIAC considered first generation computers?
They are first generation computers because they used vacuum tubes as active elements, as did almost all computers until 1958 when the first generation is usually considered to have ended. From 1958 on most computers used discrete transistors as active elements until 1964.Note: ABC & ENIAC are both very early first generation computers as they used ordinary Radio receiver vacuum tubes, not the more expensive Computervacuum tubes that were introduced about 1948 to 1949. The later Computer vacuum tubes were custom redesigned versions and were far more reliable than ordinary Radio vacuum tubes had been.
What roles has vacuum tubes played in computer development?
vacuum tubes are the switching components in the first generation computers to process data. later they were replaced by transistors.
How do you explain the generation of computer with a diagram?
A diagram that explains the generation of the computer can be found on the Scribd website. First generation computers used vacuum tubes.
