FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Early humans counted and performed simple calculations using tools such as their fingers, notches in sticks, knotted strings, and pebbles. Most early cultures evolved some form of a counting board or abacus to perform calculations.

Detailed explanation-2: -Most primitive cultures use object-specific counting, depending on what’s prevalent in their environment. For example, the Aztecs would count one stone, two stone, three stone and so on. Five fish would be “five stone fish.” Counting by a native tribe in Java begins with one grain.

Detailed explanation-3: -The word ‘Abacus’ comes from the word “abaq"  the Arab word for dust because the first abacus was simply a portable sand table; a board with dust strung across it. Eventually the board was replaced by a frame, the grooves by wire, and the pebbles by beads.
