What were the two main problems of using vacuum tubes in computers?

Valves, or vacuum tubes, were large, generated tremendous heat, and were prone to failure.
Vacuum tubes worked much like transistors, but required a filament to heat the cathode so that electrons could flow through the plate when there were the proper grid voltages for that. If the cathode heater burned out, the cathode would not work, and the tube would need to be replaced. Comparing to a PNP or NPN transistor, the cathode would be equivalent to the emitter, the plate would compare to the base, and the grid would computer to the collector. Comparing to an FET, the cathode would be the source, the grid would compare the the gate, and the plate would compare to the drain.

Why were vacuum tubes used in first generation computers?
I did't find anywhere that it was when I researched it. Over 99% of computers built from 1940 to 1958 used vacuum tubes as their active elements for: logic, power supply, memory sense/drive, etc. circuits. Other computers at this time were electromechanical, magnetic, and a small number of experimental transistor computers were built. From 1959 to about 1965 most computers used transistors as their active elements for: logic, power supply, memory sense/drive, etc. circuits. A small number off computers at this time were magnetic or used primitive monolithic ICs. From 1964 on more and more computers used ICs, of progressively increasing density.
Why transistor is so necessary?
Without the transistor you would need vacuum tubes to accomplish the same thing. None of our inexpensive portable electronics would be possible using vacuum tubes.
Did vacuum tubes replace transistors?
No the Transistor replaced vacuum tubes in 1947 and later by integrated circuits.This was answered by ...John Nelson Brundage the third seventh grader at GAISER MIDDLE SCHOOL, VANCOUVER SCHOOL DISTRICT, VANCOUVER WASHINGTON
Can you do amplification without transistor and is it possible to design oscillator using diode?
Magnetic amplifiers and vacuum tubes don't need transistors to amplificate electricity current. You can get a transistor by two oppositely connected diodes.
Seamless tubes are made by?
fabricated using quality stainless steel known as Stainless Steel Seamless Tubes
What was the first generations of computers?
The first generation of electronic computers were those implemented using vacuum tubes.
Do todays computers use vacuum tubes?
No, unless you are still using a CRT monitor.
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 is the advantage of using silicon chips instead of vacuum tubes in computers?
Smaller sizeLess heatLower voltageHigher speedHigher reliabilityEasier & quicker to assembleDisposable systemsetc.
Which is the first generation of computer?
Machines using vacuum tubes as their active elements.
What were the two main problems caused by using the valves on the colossus?
Probably rate of burnout and heat. But this was common to all vacuum tube computers, not just Colossus.

Why is radio called transistor?
Perhaps you are referring to a radio built using transistors instead of vacuum tubes.
What was the problem using valves in computers?
The main problem with valves is their reliability. A secondary problem is the sheer size. Not only are transistors far more reliable, they are very much smaller by several orders of magnitude. To get some idea of the scale, the valve equivalent of a 32 GB iPhone would be bigger than the average family house and would, therefore, be anything but portable.
How can you make a am transistor radio by using transistor?
You get two transistors and put them in a radio.
