What else can I help you with?
Transistors are generally free from which type of noise?
Partition Noise, which occurs in vacuum tubes, optical fibers etc.
Why did transistors eventually replace valves in radios?
"Valve" is the British word for Vacuum Tube, so for the British (which the person asking this question probably is) transistors did replace valves. Therefore the answer remains that values(vacuum tubes) where large and bulky, in addition they require high levels of power to function and created substantial heat and were quite fragile. The creation of the Transistor and then micro chip allowed for portability, lower levels of operation power to be required and reduced costs due to mass production
How many transistors did the ENIAC have?
Eniac didn't have any transistors. It was built with 17,468 vacuum tubes, 7,200 crystal diodes, and a whole host of other components. But no transistors. The first transistor was created in November, 1947, almost two years after Eniac was completed.
What did we use before transistors?
Before transistors, electronic circuits primarily relied on vacuum tubes to amplify signals and control electrical currents. These glass tubes contained a vacuum and used thermionic emission to operate, but they were bulky, fragile, and consumed a lot of power. Additionally, electromechanical devices like relays and rotary switches were also used for switching and signal processing in early electronic systems.
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 did colossus work without transistors?
There were vacuum tubes before transistors
What is transistorized?
A device such as a radio can be said to be transistorized when earlier designs are replaced by designs in which transistors replace 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.
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.
Vaccum tubes were replaced by what?
Vacuum tubes were largely replaced by transistors. Transistors are smaller, more reliable, and generate less heat compared to vacuum tubes. This transition led to the development of smaller and more efficient electronic devices.
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?
6u76yu
What replaced vacuum tubes in the computer?
Integrated circuits (in many microprocessor integrated circuits) containing many billions of transistors each.
Why did transistors eventually replaced the vacuum tubes?
The main advantage is that transistors use less power. A typical small vacuum tube uses about 1.8 watts to heat its cathode, plus 3-5 watts to supply the main current to the anode. By contrast a computer motherboard might take 10-20 watts to power several million transistors.
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.
