Best Answer

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.

Do todays computers use vacuum tubes?

No, unless you are still using a CRT monitor.


What kind of technology did the early computers use?

The same vacuum tubes used in radios.


Why were the vacuum tubes used instead of transistors in early computers?

Early transistors were much slower and far more expensive than vacuum tubes. Also computers built before 1948 there were no transistors to use at all.


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.=]


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.


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.


What are the uses of vacuum tubes in today's computers?

Since the second generation transistorized computers there has been no use of vacuum tubes in computers except for one thing, CRT displays. In the last few years even that has been eliminated by modern flat panel LCD & LED displays, which are much lighter and less power hungry than CRT displays were.


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 is vacuum computer?

Typically an analog computer whose signals are represented by varying vacuum levels. One common use of these was in gasoline powered vehicles (where the carburetor supplied vacuum) and they controlled things like timing advance and cruise control. Electronic digital embedded control computers have made these obsolete.One could build digital computers that represented binary values as vacuum (1) or no vacuum (0), but I have never heard of any.Perhaps you left out a word and meant "What is a vacuum tube computer?". These were the first generation digital computers, built from the 1940s to ~1958 when transistors replaced vacuum tubes in digital computers.


Why the first-generation of computer use vacuum tubes?

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).


Where do you use computers in todays world?

Where there's information to manage and machines to control.
