Detailed explanation-1: -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.
Detailed explanation-2: -Colossus was the world’s first electronic digital computer that was programmable. The Colossus computers were developed for British codebreakers during World War II to help in the cryptanalysis of the Lorenz cipher.
Detailed explanation-3: -The Colossus was developed in 1943 by engineer Tommy Flowers, based on plans by the mathematician Max Newman. It was designed to decode the encrypted transmissions from the German teleprinter Lorenz cipher.
Detailed explanation-4: -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.
