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.
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.

Colossus worked by holes punched in a paper tape. It was programmed by switches and plugs. Colossus used thermionic valves (vacuum tubes) to perform Boolean and counting operations.
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.
The simple answer is none. The Transistor wasn't invented until 1947, some 2 years after the end of World War 2.However, what they used instead, were Vacuum Tubes (also known as thermionic valves).The first true, software programmable computer was named Colossus and was built by the British to decode secret codes being used by Germany during World War 2. The code-breaking operation was so secret that the building of Colossus was only finally made public in the early 1970's !"Colossus Mark 1 contained 1,500 electronic valves (tubes). Colossus Mark 2 with 2,400 valves was both 5 times faster and simpler to operate than Mark 1, greatly speeding the decoding process"This is a quote from this site for more informationhttp:/www.absoluteastronomy.com/topics/Colossus_computer#encyclopedia
the Colossus Mark I prototype model used about 1400 tubeseach of the 10 Colossus Mark II production models used about 2400 tubes. most of extra tubes were involved in expanding the machine to have 5 parallel processors to increase the speed from the 5000 characters per second of the prototype to 25000 characters per second.

Its not Collossus, Its Colossus, One L.. Its a computer device used to decode messages in WW2..
The Expert answer is wrong, Enigma messages were cracked using electromechanical Bombe machines.The computer Colossus cracked the German "Fish" codesthat the German High Command used.
