The History of Computers

There was a british mathematician in the mid nineteenth century called charles babbage. He designed, he didn't actually build, but he designed a series of machines that a at least the most advance of which is thought to have been complete. But even considering just these type of computers, there's still a bunch of different ways you can build one. It used a decimal number system instead of binery and it worked using gears ad o levers rather than or circuits and transistors and switches and electrons flowing through wires.
