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.

How did the Colossus work without any software?
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.
What year did Tommy flowers invent colossus?
Tommy Flowers invented the Colossus, the world's first programmable digital computer, in 1943. It was designed to help break the Lorenz cipher used by the German military during World War II. The Colossus was operational by 1944 and played a crucial role in the Allied code-breaking efforts.
What is the purpose of valves in a pneumatic system?
Valves in a pneumatic system regulate the flow and direction of compressed air, controlling the operation of actuators and other components. They enable precise control over the speed and movement of machinery, ensuring efficient and safe operation. Additionally, valves can help isolate sections of the system for maintenance or troubleshooting. Overall, they play a crucial role in the functionality and reliability of pneumatic systems.
How many valves are available in machines?
they have two - four valves
What is the difference between plug valves and globe valves with plug?
A Plug Valve is a Globe Valve. Very generally speaking there are two major catagories of Industrial Process Control Valves, Sliding Stem and Rotary. Globe Bodies valves fall into the category of Sliding Stem Valves. Butterfly and Ball valves fall into the category of Rotary valves. However there are what is referred as Rotary Plug Valves, whereby a partial sphere has a shaft eccentrically mounted, that rotates into and out of a metal or composition seat acting as a plug. Most plug valves are sliding stem.
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
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 many valves were used on each of the 10 colossus machine?

How many valves was on the colossus?
69
What was the role of the colossus 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 were the 2 main problems of the valves in the colossus?
The two main problems with the valves in the Colossus were their tendency to stick and their susceptibility to overheating. The design of the valves made them prone to mechanical failures, which could lead to reduced performance and reliability in the machine. Additionally, the high temperatures generated during operation exacerbated these issues, further impacting the overall functionality of the Colossus.
How did the Colossus work without any software?
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.
What were the two main problems caused by using the valves on the colossus?
Probably rate of burnout and heat. But this was common to all vacuum tube computers, not just Colossus.
