FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The earliest known calculating device is probably the abacus. It dates back at least to 1100 bce and is still in use today, particularly in Asia. Now, as then, it typically consists of a rectangular frame with thin parallel rods strung with beads.

Detailed explanation-2: -Early History of Computer One of the earliest and most well-known devices was an abacus. Then in 1822, the father of computers, Charles Babbage began developing what would be the first mechanical computer. And then in 1833 he actually designed an Analytical Engine which was a general-purpose computer.

Detailed explanation-3: -abacus, plural abaci or abacuses, calculating device, probably of Babylonian origin, that was long important in commerce. It is the ancestor of the modern calculating machine and computer.

Detailed explanation-4: -The abacus represents the earliest known computational device in that it incorporates the four central components of computational devices. (1) A structure serving as the representational medium. I the abacus the rods and beads serve as the structure.

Detailed explanation-5: -It was the arithmetic process of Abacus that led to the development of Computers. While abacus is an ancient calculating tool, Computers are modern tools, which performs many functions. The computers have become part and parcel of human beings. Abacus can also be called as the oldest computer.
