Abacus and Calculator meaning in Electronics

Abacus and Calculator meaning in Electronics


Abacus is a calculating device which consists of balls strung on wires or rods set in a frame. It is almost certainly of Babylonian origin but its use decreased in Europe with the beginning of Arabic numerals in about the 10th century AD. Until recently it was still use in the Middle East and Japan. Ancient types of abacus have also been found in China, thought that same to have taken there by Arabic traders. The first known use of them in China was during the twelfth century where the device was called the ‘Suan-Pan’. It can be used to do mathematical functions such as addition, subtraction, multiplication and division and to calculate square roots and cube roots.



It is a device that adds, subtracts, multiplies and divides with accuracy and speed. A mechanical calculator was built by the German mathematician Wilhelm Schickard in 1623 using a set of metal wheels. Around 1642 the French Mathematician Blaise Pascal made a similar machine that could handle up to nine digit numbers. In 1673, the German Mathematician Gottfried Lelbniz made a device similar to Pascal’s. Beginning in the 1960’s electronic calculators and digital computers became very popular. Besides adding, subtracting, multiplying and dividing many electronic calculators perform more complicated functions such as extracting square roots and cube roots. Many models also contain a memory in which numbers and instructions for solving problems can be stored for future use.
