- My wife did buy the set of gold (14 crt) abacus cufflinks in Hong Kong during the early 1970's. The beads are all individual movable.

Measures: H x B = 2 x 1.2 cm

 

- Abacus is known to be the first mechanical calculating device. Which was used to be performe addition and subtraction easily and speedily.

This device was developed by the Egyptians in the 10th century B.C, but it was given its final shape in the 12th century A.D. by the Chinese educationists.

These Abacus were made up of a wooden frame in which rods where fitted across with rounds beads sliding on the rods. It is divided into two parts called ‘Heaven’ and ‘Earth’. Heaven was the upper part and Earth was the lower one. Thus any number can be represented by placing the beads at proper place.

 

- 'Micro processors’ are the main concept behind modern computers.

A microprocessor is a single chip (L.S.I. circuit), which is used in a computer for any arithmetical or logical function to be performed in any program.
