<P> Charles Babbage , an English mechanical engineer and polymath , originated the concept of a programmable computer . Considered the `` father of the computer '' , he conceptualized and invented the first mechanical computer in the early 19th century . After working on his revolutionary difference engine , designed to aid in navigational calculations , in 1833 he realized that a much more general design , an Analytical Engine , was possible . The input of programs and data was to be provided to the machine via punched cards , a method being used at the time to direct mechanical looms such as the Jacquard loom . For output , the machine would have a printer , a curve plotter and a bell . The machine would also be able to punch numbers onto cards to be read in later . The Engine incorporated an arithmetic logic unit , control flow in the form of conditional branching and loops , and integrated memory , making it the first design for a general - purpose computer that could be described in modern terms as Turing - complete . </P>
