device description
abacus used beads for arithmetic
slide rule used rulers for multiplication
adding machines used gears for addition

what was the first computer?

In 1833 Charles Babbage invented the first mechanical computer, called the “difference engine”. It was intended to be used with the calculation of mathematical and astronomical tables; to aid in navigation. The first version was unsuccessful because the metalworking techniques of the time could not make parts the required.

The idea of the modern computer, as we know it today, was proposed by Alan Turing in 1936.
