Abacus

Abacus was designed by the Chinese around 4000 years ago. It’s a wood shelf with steel poles with grains attached to them. The abacus driver relocates the grains according to particular standards to complete arithmetic calculations.
Napier’s Bone
John Napier devised

Background of Computer Systems Generation.
The word ‘computer system’ has a really interesting origin. It was first made use of in the 16th century for a person that made use of to calculate, i.e. do calculation
