Why was the Colossus machine kept secret for 30 years?

News of the existence of the Colossus, widely regarded as the first electronic computer, was kept top secret for 30 years partly because of the sophistication of its methods to help break Lorenz messages by finding the frequently changing wheel patterns of the Lorenz encryption machine.

Why was the Colossus computer important?

Colossus, the world’s first electronic computer, had a single purpose: to help decipher the Lorenz-encrypted (Tunny) messages between Hitler and his generals during World War II. The Colossus Gallery houses the rebuild of Colossus and tells that remarkable story.

How did the Colossus computer changed the world?

Is Colossus at Bletchley Park?

How did the Colossus computer work?

Running Colossus The Colossus machine was driven by the tape reader which scanned punch holes in a tape representing the cipher text of a message. The punch holes were converted by a photoelectric reader into a sequence of pulses which were then sent to the arithmetic and logic circuits of Colossus for processing.

What technology did the colossus use?

Colossus weighed at least a ton and took up an entire room Colossus was programmed using switches, wheels and plugs, and German messages were fed into it via punched paper tape inputs that were capable of tackling 5,000 characters per second.
