the first electronic computers were built before the invention of the transistor or integrated circuit chip. They used vacuum tubes for the processing and temporary memory. In Britain those tubes were called valves.

How many valves were used on each of the 10 colossus machine?
The Colossus was built using thermionic valves, thyratrons, relays and stepping switches.The Colossus Mark 1 used about 1600 valves and the Colossus Mark 2 used about 2400 valves. After the Colossus Mark 2 was in production and use the single Colossus Mark 1 was briefly shutdown and upgraded to a Colossus Mark 2. Five of the ten Colossus machines also had a device called the "gadget" that aided in a process called "rectangling", the number of additional valves added to each of these enhanced Colossus Mark 2 machines is unknown.
What were the two main problems caused by using the valves in colossus computer?
Reliability and heat were the main problems. Valves were fragile devices that, due to the relatively primitive way they were manufactured, failed pretty quickly. In addition to that, they gave off vast amounts of heat. This meant they needed expensive air-conditioning systems to keep their temperature down.
What was the third computer called?
Since an Abacus is technically a computer, I can only assume you mean the third binary electronic computer. This was called "Colossus Mark 1" and was developed in the UK to read encrypted German messages during World War II.The Colossus machines were the first programmable, digital, electronic, computing devices and went through several revisions so if you define a computer in this way, a Colossus machine would still have been the third computer device ever to be constructed.After World War Two all the blueprints and Colossus hardware were destroyed in the interests of National Security and it was not for many years that its designers would receive the credit they deserved for the world's first programmable electronic computer.
Is the colossus computer still here?
The original machine is not - however... construction of a working machine was reconstructed in 2007.
The inventor of the collosus computer?
Tommy Flowers with input from Allen Coombs, Sid Broadhurst and Bill Chandler.
What part of the colossus computer enabled it to do the processing?
The Colossus computer worked using one to two thousand thermionic valves.
What are some of the Colossus computer problems with valves?
they were huge and you needed loads
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.
What were the two main problems caused by using the valves on the Colossus computer?
Probably rate of burnout and heat. But this was common to all vacuum tube computers, not just Colossus.

Colossus was developed during World War 2. What was it and what was it used for?
Colossus was a very large computer that used valves - a far cry from a modern desktop computer. It was used to help break the German's Enigma Code.
How did the Colossus get it to work?

Why was the colossus computer desgined for?
the main objective of the colossus was to break the enigma code
How was the computer made?
A variety of methods were employed, from electromechanical telephone relays (Zuse KG Z3) to thermionic valves (ABC, Colossus, etc).
