FUNDAMENTALS OF COMPUTER

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: -Difference Engine, an early calculating machine, verging on being the first computer, designed and partially built during the 1820s and ‘30s by Charles Babbage.

Detailed explanation-3: -Charles Babbage (1791-1871), computer pioneer, designed two classes of engine, Difference Engines, and Analytical Engines.

Detailed explanation-4: -The Analytical Engine was a proposed mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. It was first described in 1837 as the successor to Babbage’s difference engine, which was a design for a simpler mechanical calculator.

Detailed explanation-5: -Alfred Deacon of London in c. 1862 produced a small difference engine (20-digit numbers and third-order differences).
