History Of Computers!!
"Who invented the computer?" is not a question with a simple answer. The real answer is that many inventors contributed to the history of computers and that a computer is a complex piece of machinery made up of many parts, each of which can be considered a separate invention.
I have given many of the major milestones in computer history(but not all of them)with a concentration on the history of personal home computers.
