The world's first computer was built by [[Charles Babbage]] in 1833, which he called the '''Analytical Engine'''.  It was powered by steam and could perform basic arithmetic calculations with accuracy up to six decimal places.  It also featured a 'bit bucket' in the back that collected discarded and malformed bits resulting from the calculations; this bucket had to be emptied on a weekly basis. Charles Babbage's wife [[Ada Augusta]], whom operated the Analytical Engine, is considered to be the world's first computer programmer.

Prior to the advent of computing machines, a ''computer'' was a human being who performed complex mathematical calculations.
