Colossus was a set of computers developed by British codebreakers in the years 1943–1945 [ 1] to help in the cryptanalysis of the Lorenz cipher. Colossus used thermionic valves (vacuum tubes) to perform Boolean and counting operations. Colossus is thus regarded [ 2] as the world's first programmable, electronic, digital computer, although it ...
