MICROPROCESSOR AND MICROCONTROLLER

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 difference engine is a mechanical calculator first developed by Charles Babbage in 1822. It can compute several sets of numbers and make a hard copies of the results. Due to a lack of funding, he was never able to complete a full-scale functional version of this machine.
