Detailed explanation-1: -Charles Babbage began to construct a small difference engine in c. 1819 and had completed it by 1822 (Difference Engine 0).
Detailed explanation-2: -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-3: -By 1822 Babbage had constructed a model of his Difference Engine No. 1, a special-purpose calculating machine far more complex than any that had previously been conceived, designed to compute mathematical tables by the method of finite differences and to print the results.
