The Evolution of Computers

    Computers or better known as devices that helped aid computation have been used for thousands of years, mostly using one-to-one correspondence. One-to-one correspondence meaning a set paired with another set where each element in one of the sets is paired with exactly one element from the other set. These computers came to be known as counting devices. These devices were really only used to help you count and keep records and not much more. The earliest counting device dated back to the Upper Palaeolithic or the Old Stone Age.
