Detailed explanation-2: -The first “computers” were people-individuals and teams who would tediously compute sums by hand to fill in artillery tables. Inspired by the work of a computing team in revolutionary France, Charles Babbage, a British mathematician, created the first mechanical device that could organize calculations.
