A vacuum tube is a current amplifier where the transistor amplifies voltage
A tube is a voltage amplifier. A transistor is a current amplifier. A tube is an older design that requires substantial voltage to operate correctly. A transistor is a semiconductor device that operates on relatively low voltage.

Construction: Vacuum tube are vacuum tubes that have a sealed glass or metal container from which most of the air has been removed, leaving a vacuum inside. They have a heated cathode, one or more control grids, and an anode. In contrast, transistors are semiconductor devices that are made from a thin slice of silicon or germanium material.
Size: Vacuum tube are much larger than transistors, which are very small and can be manufactured using automated processes. This makes transistors ideal for use in portable electronics, such as smartphones and laptops.
Power consumption: Vacuum tube consume more power than transistors. Transistors require very little power to operate and are more efficient, making them well-suited for battery-powered devices.
Reliability: Transistors are more reliable than Vacuum tube. They have a longer lifetime and lower failure rate than Vacuum tube, which can be prone to breakage and wear and tear.
Amplification: Vacuum tube can handle high voltages and high power applications with ease, making them ideal for use in power amplifiers, radio transmitters, and other applications that require high output power. Transistors, on the other hand, have a much lower power output but are much more efficient and can be used in a wide range of electronic devices.
Warm sound: Vacuum tube have a unique "warm" sound that is prized by some audiophiles. Transistors, in contrast, have a more neutral sound.

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.
What were used before transistors?
If the integrated circuit in some kind of device has 5,000 transistors on it, then before integrated circuits were available, the same function might have been performed by 100 individual transistors. And before transistors were available, the same function might have been performed by 30 vacuum tubes, a fan and air system to keep them cool, and a large power system to operate the tubes and the cooler.
What is the purpose of transister?
The correct spelling is transistor. The definition of transistor is a portable radio that uses circuits that contain transistors instead of vacuum tubes. It is a semiconductor device that has three connections.
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 electronic devices contain transistors?
Practically everything. Even devices using electron tubes (e.g. microwave cookers, high power radio and TV transmitters) now generally use transistors to control the tubes.
How did colossus work without transistors?
There were vacuum tubes before transistors

Transistors replaced to amplify electric signals?
vacuum tubes
What technology replaced vacuum tubes in the second generation?
Vacuum tubes were first replaced by transistors, and later by integrated circuits.
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 vacuum tubes and transistors?
They are devices that are used to control the flow of current.
What are the advantages oe transistors over vacuum tubes?

What replaced vacuum tubes in the computer?
Integrated circuits (in many microprocessor integrated circuits) containing many billions of transistors each.
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.
Are there home theater systems available that use vacuum tubes instead of transistors?
yes, and vac tubes are the most efficient
What was the first computer consisted of?
Mostly vacuum tubes, in place of today's more modern transistors.
Why second generation computer more reliable?
Transistors ran cooler than Vacuum tubes.
