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.
What else can I help you with?
How did the Colossus get it to work?
using valves
What are the problems with valves in a computer?
Valves, as used in an old wireless/radio, is not used in modern computers.
What are the Components of first generation of computers?
vaccum tubes and valves.
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 did the colossus need valves?
Because - when Colossus was built (in 1943), microchips had yet to be invented ! Microchips replaced valves and transistors in newer computers.
How many valves are on modern computers?
None. Valves are not used. Integrated circuits are now the mainstay of most electronic devices.
What has been used to replace valves in modern computers?
They haven't been replaced! Only now they are much smaller and switched on and off by nano-bots that receive instructions from user input.
How does computing valve work?
Just like the valves used in valve stereo equipment or old radios. Except in computers (like the transistors in modern computers) valves are usually driven fully into saturation and cutoff, while in a valve stereo or old radio valves are usually operated as linear amplifiers with minimal distortion.

Which technique can be applied to discover new undecidable problem?
Using computers as an example, just whack it a few times until lights flash. You might discover a new 'undecidable' problem.
