Colossus was made for decoding German messages. It was the first computer made but only was used t decode and kept secret til after wwII.
Howard H.Aiken created an electronic calculator in 1944. Named mark 1 it was a long machine that was slow and inflexible. John Presper Eckert and John W. Mauchly created Computer Eniac, it took a lot of power and was much faster than Colossus and Mark1. It was also used for calculations in building the atomic bomb.
John von Neumann build the automatic computer, his began to store memory of data that was used.
