The dual triodes were used as flip-flops in computers. this is basically the same operation as we have now i.e. yes - no. The triode opens a gate to allow electrical pulses through based on a positive or negative response. Today we have the same operation but inside microchip technology when now is faster and more reliable as it used gates
The Colossus computer worked using one to two thousand thermionic valves.
Probably rate of burnout and heat. But this was common to all vacuum tube computers, not just Colossus.

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 actual computers called Colossus were World War II code-breaking computers built in 1943 and 1944 in Bletchley Park, Buckinghamshire, England. These were the first true programmable computers, and about a dozen were built.The prototype, Colossus Mark I, was shown working in December 1943 and was operational at Bletchley Park by February 1944. An improved Colossus Mark II was first installed in June 1944, and ten more had been constructed by the end of the war. Unfortunately, the secret nature of these computers meant that their innovations were not available for commercial computer development for many years.*The other computer called Colossus is a fictional artificial intelligence from a 1965 novel (Colossus) by Dennis Feltham Jones, which was the basis for the film Colossus, the Forbin Project in 1970

they were huge and you needed loads
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 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.
using valves
using valves
Because - when Colossus was built (in 1943), microchips had yet to be invented ! Microchips replaced valves and transistors in newer computers.
the main objective of the colossus was to break the enigma code
A variety of methods were employed, from electromechanical telephone relays (Zuse KG Z3) to thermionic valves (ABC, Colossus, etc).
