Describe two problems associated with vacuum tubes in the first computers?
I'm not sure what you mean by "this computer" but vacuum tubes have the following problems anywhere they are used:high voltage required for operationget very hotshort lifetime, heater burns outlarge physical size
1st generation of computer?
First generation computers were built with vacuum tubes. The capabilities were about the same as that of modern computers, except limited by very small memories and slow speed. Typical first generation computer memory cost from $2 to $20 per byte equivalent, whereas today's computer memory costs less than a micro-penny per byte.
How did the first electronic computers of the 1940s and 1950s compare to the modern PCs?
Very slow, big, and hot. On the issue of speed a typical memory cycle took on the order of 100 microseconds although there were both faster and slower machines. On the issue of size and heat until about 1958 practically all computers used vacuum tubes, even the smallest vacuum tubes were at least 3/4 inch in diameter and a couple of inches tall and dissipated several watts of power keeping their cathodes red hot.
Why were researchers looking for a replacement for vacuum tubes?
Bell Labs researchers were unsatisfied with the low reliably, high power usage, and large size of the vacuum tubes that needed to be used in the telephone switching and long distance trunk systems of the 1940s.
What allowed us to put mainframe computers on your desks?
A mainframe computer is a large wall size gadget with cables running into The ENIAC filled a 20 by 40 foot room, weighed 30 tons, and used more than 18,000 vacuum tubes. Later in history processor came to live. This is what shrink it size to a most modern computer. It is still bringing computers more compact today.

How did a computer work before a microprocessor?
They could only perform basic calculations.

Do vacuum tubes did it lead to an increase or decrease in size?
Vacuum tubes initially led to an increase in size of electronic devices due to their bulky nature and need for additional components. However, as technology advanced, the development of smaller, more efficient components such as transistors and integrated circuits led to a decrease in size of electronic devices.

What are the Advantages and disadvantages of 1st generations of computer?
The use of transistors instead of vacuum tubes in second generation computers made them:smallerfastercheaperlighterrun coolerconsume less powermore reliableeasier to maintainetc.
How are solid state components like vacuum tubes?
Solid state components, such as transistors, are more reliable and efficient than vacuum tubes. They are smaller in size, produce less heat, and consume less power. Additionally, solid state components do not require warm-up time like vacuum tubes do.
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.
