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.

Because - when Colossus was built (in 1943), microchips had yet to be invented ! Microchips replaced valves and transistors in newer computers.
the answer for this is: the purpose the holes in colossus was it felt like it
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.
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 computer worked using one to two thousand thermionic valves.
they were huge and you needed loads
