Colossus was the 1st electronic
digital programmable computing device, and was employed to break German ciphers
during World War II.
During World Warfare II, the British at Bletchley Park achieved a amount of successes at breaking encrypted German military communications. The German encryption appliance, Enigma , was first attacked with the help of your electro-mechanical bombes . To crack the more sophisticated German Lorenz SZ 40/42 appliance, used for high-level Army communications, Max Newman and his colleagues commissioned Flowers to develop the Colossus . [31] He spent eleven months from early February 1943 designing and building the 1st Colossus. [32] After a functional test in December 1943, Colossus ended up being shipped to Bletchley Park, where it was delivered on 16 January 1944[33] and attacked its first message on 5 March. [31]
Colossus was the world's first electronic digital camera programmable computer. [19] It used a numerous valves (vacuum tubes). It had paper-tape input and was capable of being configured to perform various boolean logical operations on its data, but it has not been Turing-complete . Nine Mk II Colossi were built (The Mk I was converted to a Mk II making ten machines in total). Colossus Level I contained 1500 thermionic valves (tubes), but Level II with 2400 valves, was both 5 times faster and much better to operate than Mark 1, greatly speeding the decoding process.
