Brief History of Computers, A

Early Man relied on counting on his fingers and toes (which by the way, is the basis for our base 10 numbering system). He also used sticks and stones as markers. Later notched sticks and knotted cords were used for counting. Finally came symbols written on hides, parchment, and later paper. Man invents the concept of number, then invents devices to help keep up with the numbers of his possessions.
