- the Colossus Mark I prototype model used about 1400 tubes
- each 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.

∙ 10y agothe 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.

∙ 9y agoThe 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

What part of the colossus computer enabled it to do the processing?
The Colossus computer worked using one to two thousand thermionic valves.
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.
What was the purpose of those holes colossus?

How many transistors does a world war 2 computer have?
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
When was the Colossus computer built?
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

What are some of the Colossus computer problems with valves?
they were huge and you needed loads
How many valves were used on each of the ten colossus machines?
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.

How many valves was on the colossus?
69

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?
using valves
How did they get colossus to work?
using valves
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.
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).
