GENERAL KNOWLEDGE

Detailed explanation-1: -The Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world’s first working programmable, fully automatic digital computer. The Z3 was built with 2, 600 relays, implementing a 22-bit word length that operated at a clock frequency of about 5–10 Hz.

Detailed explanation-2: -The Colossus was developed in 1943 by engineer Tommy Flowers, based on plans by the mathematician Max Newman.

Detailed explanation-3: -Zuse worked throughout WWII on other designs, culminating in his Z3 computer, the world’s first fully operational stored-program electromechanical computer. He was able to sell one to the German aircraft bureau, which needed it to solve aerodynamic problems.
