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: -The first computer was invented by Charles Babbage (1822) but was not built until 1991! Alan Turing invented computer science. The ENIAC (1945) was the first electronic general-purpose digital computer; it filled a room. The Micral N was the world’s first “personal computer”(1973).
Detailed explanation-3: -He first attempted to create a so-called difference engine, which would be able to calculate mathematical and astronomical tables by turning a crank. Later, he expanded upon this idea by proposing an analytical engine, which would be a device that could be programmed to perform any calculation.
Detailed explanation-4: -Charles Babbage (1791-1871), computer pioneer, designed the first automatic computing engines. He invented computers but failed to build them. The first complete Babbage Engine was completed in London in 2002, 153 years after it was designed. Difference Engine No.
