Who was the first to use computers?
Depending on your definition, it is hard to pinpoint exactly when and where computers began, mechanical computers have been found as far back in history as the Roman Empire. The first practical use of an electronic computer may have been the colossus computer at the Bletchley Park cryptanalysis center during World War Two. The colossus computer was used to decypher Nazi Germanys enigma encryption system. Thanks to this computer, the allies were able to reliably intercept and decode Nazi communications resulting in an instrumental strategic advantage. Many have postulated that without the efforts of the technicians at Bletchley Park, the war may have stretched on a further five years or more and may have turned the tables of victory in favor of the Nazis. After the war, the equipment and designs at Bletchley remained top secret, and much of it was destroyed. The technicians who built and used the colossus were not permitted to discuss their vital role in the war effort until decades later.
