The abacus dates back to between 2,700 and 2,400 BCE (over 4,000 years ago) and was developed in Sumeria. It is actually a calculating aid and not an automatic device.
Originally it may have been used by storekeeper, traders and government officials who needed to perform basic calculations. The system used a number of pebbles (or beads) placed in columns on a board or attached to a string.
Each column represented a multiple of 10; to to produce the number 634 you would place 6 beads in the 100's column, 3 beads in the 10's column and 4 beads in the 1's column. By adding and deducting beads you could quickly and accurately perform relatively complex calculations without having to try and keep all the numbers in your head while doing so.
