- The first digital computer that used vacuum tubes was the ABC, completed in 1942 by Dr. John Vincent Atanasoff and Clifford Berry in Ames, IA.
- An early analog computer that used vacuum tubes was the Differential Analyzer, completed in 1929 by Vannevar Bush and a large team at MIT. (there probably were other smaller analog computers of this type that used vacuum tubes before this, so it probably isn't the first but its the earliest where I can find it clearly documented).

Why are Vacuum tubes important for computer memory?
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.
How many vocum tubes were in the eniac?
The ENIAC has 17,468 vacuum tubes. These tubes were the first technology that made computers function. Modern computers do not use this technology.
Did Alan Turing made the vacuum tubes computers?
No, he had to use mechanical gears, etc. because they were the only device technology available in his time. Electric relays were first developed about 15 years after he designed his computer, while vacuum tubes were first developed about 90 years after he designed his computer.
Use of vacuum tube in first generation of computer?
It's purpose was to act like an amplifier and a switch. Without any moving parts, vacuum tubes could take very weak signals and make the signal stronger (amplify it). Vacuum tubes could also stop and start the flow of electricity instantly (switch). These two properties made the ENIAC computer possible.
What are the benefits of vacuum tubes?
vacuum tubes help us today with many things. the most important 1 is techology. If we didn't have vacuum tubes we wouldn't have computers. just thik of a life with out computers or t.v. vacuum tubes are also used in radios. so if vacuum tubes hadn't been invented we would not be able to use all the techology we use today.=]

Which was the first computer to use vacuum tubes instead of mechanical swiches?
ABC, finished in 1942.

Why modern devices use integrated circuit instead of vacuum tubes?
Modern devices use integrated circuits instead of vacuum tubes because integrated circuits occupy less space than vacuum tubes, are more efficient, consumes less energy and are more reliable than vacuum tubes.

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.
What was the element neon used for in the past?
they use it neon lights, vacuum tubes, television tubes, lasers, and as a refrigerant
Are there home theater systems available that use vacuum tubes instead of transistors?
yes, and vac tubes are the most efficient

What did ENIAC use instead of mechanical parts?
it used 1800 vacuum tubes
What do you call the vacuum tubes used in transistor radios?
You don't, there aren't any. However some radios in the early 1950s did use both vacuum tubes and transistors. This was because early junction transistors were too slow to operate at RF so vacuum tubes were used in the RF and IF sections. These radios were called hybrid radios because they used both vacuum tubes and transistors.
