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.=]
No advantages, only disadvantages. Cathodic ray tubes are out of date.
They take too much space, waste more energy, esthetically less attractive than LCD screens.
first generation calculating device
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.
vacuum tubes are the switching components in the first generation computers to process data. later they were replaced by transistors.

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.
Overall, computers with vacuum tubes were not reliable nor did very much. Vacuum tubes took up lots of space and got very hot. The lifespan of vacuum tubes were not much better than incandescent light bulbs, and if a computer had hundreds of these, the odds of one going out soon would be quite high. The vacuum tubes didn't switch all that fast either, and they had to be heated before they could be used, meaning it took about a minute or so before anyone could attempt to boot it.
They enable us to do things at night.
It replaces the big heat wasting vacuum tubes. They are lighter, smaller, and more sturdy.
It used 5200 vacuum tubes.
No, there are some cold cathode vacuum tubes. These do not light.
This would depend on the type of vacuum tubes needed. Any car part store will carry vacuum tubes for a car, general stores carry vacuum tubes for household vacuums, and AC part stores will carry vacuum tubes for the AC/Heating system of a house.?æ

Vacuum tubes were first replaced by transistors, and later by integrated circuits.
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.

Vacuum tubes vary from thumb size to larger than most people. Integrated circuits or ICs' are the size of you little finger nail. There was nothing worth remembering before vacuum tubes.
