Who invented computers and its accessories?

Charles Babbage is called the Father of Computers. Accesories as of today are manufactured by HCL.IBM,ACer,HO,Etc.

Originally, the term "computer" referred to a person who performed numerical calculations (a human computer), often with the aid of a mechanical calculating device. Examples of early mechanical computing devices included the abacus, the slide rule and arguably the astrolabe and the Antikythera mechanism (which dates from about 150-100 BC). The end of the Middle Ages saw a re-invigoration of European mathematics and engineering, and Wilhelm Schickard's 1623 device was the first of a number of mechanical calculators constructed by European engineers

I thoght it was John V. Maucley and J presper Echert who invented the first computer when they made the eniac at Moore in Pennsylvania.
