A Transistor is an electronic device which amplifies electrical signals, or acts as a switch. Most of the research on Transistors was performed by Shockley in 1947. That was when, the advantages of the solid state device similar in function to a Triode Vacuum tube were understood and implemented. The basic advantage was compactness..
What else can I help you with?
How did colossus work without transistors?
There were vacuum tubes before transistors
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 replaced vacuum tubes in the computer?
Integrated circuits (in many microprocessor integrated circuits) containing many billions of transistors each.
Features of second generation computer?
transistors : replace vacuum tubes smaller and cheaper less heat dissipation solid state device made from silicon(sand)
What are the elements of a vacuum tube?
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).
What computer component did the transistor replace?
the vacuum tube
What is the difference between vacuum tubes and transistors?
A vacuum tube is a current amplifier where the transistor amplifies voltageA 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.
What displaced the vacuum tube in most electrical circuits?
Solid state electronics (diodes and transistors primarily)
How much should it cost to replace a vacuum tube on a Ford Focus 2002?
It will cost you about $743.00 to replace a vacuum tube on a Ford Focus 2002.
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.
Do vacuum tubes in computers burn out like light bulbs?
Yes, vacuum tubes in computers burn out. Transistors are much better. Vacuum tube computers no longer exist except in museums. Vacuum tube computers were originally made in World War 2 to calculate the positioning of antiaircraft guns. It was not necessary to know where the airplane was but where it would be when the explosive arrived. That was especially true when the Germans developed the buzz bomb going 450 miles an hour. When hundreds of transistors could fit in the same area as one vacuum tube, the vacuum tube vanished.
Transistors placed in computers?
The transistor was originally used in computers to replace the vacuum tube. The function of the vacuum tubes was to regulate the flow of energy throughout the computer in order to answer a function. Transistors are semiconductors that are most commonly embedded in Central Processing Unit (CPU) chips. These "electric flow regulators" act as microswitches to help the computer "think."
Advantages and disadvantages of vacuum tube?
Vacuum tubes have superior sound quality and are typically easy for the user to replace on their own. Disadvantages include their size, rather large for portable devices, and they generally use a larger amount of power then 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.
How did colossus work without transistors?
There were vacuum tubes before transistors
What can perform the same functions as transistors but they are larger give off more thermal energy don't last as long and are tube shaped?
Vacuum tubes
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
