FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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.

Detailed explanation-2: -The original colossus was an enormous statue that was supposed to have guarded the ancient Greek island and city of Rhodes. Now, though, we use the noun colossus for someone of huge importance, reputation, or influence.

Detailed explanation-3: -The prototype, Colossus Mark 1, was shown to be working in December 1943 and was in use at Bletchley Park by early 1944. An improved Colossus Mark 2 that used shift registers to quintuple the processing speed, first worked on 1 June 1944, just in time for the Normandy landings on D-Day.

Detailed explanation-4: -Colossus I, built at the Post Office Research Station in Dollis Hill, London, was delivered to Bletchley Park by a Post Office motortruck in January 1944-a pivotal, if secret, moment in the history of computers.
