Detailed explanation-1: -Babbage began in 1821 with Difference Engine No. 1, designed to calculate and tabulate polynomial functions. The design describes a machine to calculate a series of values and print results automatically in a table.
Detailed explanation-2: -From the IBM Archives: The Automatic Sequence Controlled Calculator (Harvard Mark I) was the first operating machine that could execute long computations automatically.
Detailed explanation-3: -Before ABC, there were mechanical computing devices that could perform simple calculations. The first mechanical computer, The Babbage Difference Engine, was designed by Charles Babbage in 1822. The ABC was the basis for the modern computer we all use today. The ABC weighed over 700 pounds and used vacuum tubes.
