in 2000 a. c One of the earliest mechanical calculations was the counter of the Egyptian sand, consisting of groove in the sand where they placed stones or pebbles.

2600a.C. :One of the first mechanical counting device was the abacus, the history of the ancient Greek and Roman civilizations dating. This device is very simple, consists of beads strung on rods which in turn are mounted on a rectangular frame. By moving the beads on rods, their positions represent stored value, and it is through these positions it represents and stores data.

this is how the computer has evolved, it is rumored that 2015: Future quantum computers would use a physical phenomenon known as "overlap" where infinitesimal size objects like electrons, can exist in two or more places at once . This would mean that future computers created with "stacked" processors could use quantum bits (called "qubits" quantum bits). A qubit has the ability to represent two states: "0" and "1" simultaneously.
