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 did colossus work without transistors?
There were vacuum tubes before transistors
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 did the Colossus get it to work?
using valves
How did they get colossus to work?
using valves

How many valves was on the colossus?
69
Why did the Colossus computer need valves?
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.
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
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.
Are transistors bigger or smaller than valves?
Yes they are. The invention of the transistor signalled the end of large, bulky valves in circuits. Modern transistors are so small - that thousands can be housed on one microchip.
