what is abacus in computer

An abacus is a mechanical device used for counting and performing mathematical operations such as addition, subtraction, multiplication, and division. It is a calculating tool used since ancient times in various civilizations such as Ancient Greece, Rome, China, Russia, and Babylon. The abacus consists of a rectangular frame that holds vertically organized rods on which beads move up and down. The main purpose of an abacus is to increase the brainpower of children and improve their concentration level. The abacus is also used to explain how computers manipulate numbers, and modern computer operating systems use binary abacus to read numbers. The abacus is still used in modern times, and an adapted abacus, called a Cranmer abacus, is commonly used by visually impaired users to perform mathematical functions such as multiplication, division, addition, subtraction, square root, and cube root.
