History of Computers This project explains the history of computers, starting from Howard Aiken’s Harvard Mark I to present day time. Although I have not gone over all of the models in my report, I have chosen those which I feel have had the greatest effect on the computer world. I will show how in just forty years, computers have come from complex, slow, room-sized machines, to the small and fast computers of today. These powerful machines are the art of many great men and women, which I will also briefly explain in the project. This project is to show others how these machines, that run many aspects of our life, have come from.
