COMPUTER FUNDAMENTALS

Detailed explanation-1: -In 1821 Babbage invented the Difference Engine to compile mathematical tables. On completing it in 1832, he conceived the idea of a better machine that could perform not just one mathematical task but any kind of calculation.

Detailed explanation-2: -Analytical Engine, generally considered the first computer, designed and partly built by the English inventor Charles Babbage in the 19th century (he worked on it until his death in 1871).

Detailed explanation-3: -Charles Babbage, born to a wealthy London family in 1791, was the brain behind the idea, and is famous for his work developing plans for two different computers. His first, the Difference Engine, was partially completed in the early 1830s, but never to the extent he had planned.

Detailed explanation-4: -What was the Difference Engine? It was an automatic calculating machine designed by Charles Babbage (1791– 1871), English mathematician and polymath. He conceived the machine in 1821, in response to a dismaying number of errors in mathematical tables calculated by hand.
