Detailed explanation-1: -A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions. It was designed in the 1820s, and was first created by Charles Babbage .
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: -The Difference Engine was a large, heavy mechanical construction operated by a hand crank. Gears moved numerical counters in order to supply complex results.
Detailed explanation-4: -Still, the British adopted his proposed two-shilling piece, or florin, making ten florins equal to a pound sterling. Babbage never fully finished the expanded Difference Engine, which he began calling the “Analytical Engine, ” but parts of the original ran smoothly in displays and kept bringing him more attention.
Detailed explanation-5: -For a complex variety of reasons, Babbage failed to build a complete Difference Engine. His engineer, Joseph Clement, completed one-seventh of the full machine in 1832; it worked impeccably, but the project was abandoned following a dispute about payment.
