heeelo people of the world :)
the history about the abacus is that 3000 years ago the chinese invented the abacus. The abacus was made of wood parrelel rod and beads.
A Chinese abacus is called a Suan Pan. It works because it is based upon the decimal system, so the beads are used to count groups of ten.
12
The number 9 is the maximum number of beads on an abacus because it is the last number in the ones place before the tens place is reached.. The abacus is a tool that was used for arithmetic in ancient times. It is composed of a frame with a series of rods or wires on which beads are strung. The beads are used to represent numbers.
The Chinese abacus was developed about 5000 years ago. It was built out of wood and beads. It could be held and carried around easily. The abacus was so successful that its use spread form China to many other countries. The abacus does not actually do the computing, as today's calculators do. It helps people keep track of numbers as they do the computing.

If you are refering to Chinese abacus their earliest rudimentary design of abacus has 1/4 rod beads (quite similar to the later Japanese soroban abacus). Various other types of abacus design were also seen afterwards, but the advance type of 2/5 rod beads became standard and classic. Afterwards, the basic 1/5 rod beads particularly became the type of basic design. The Roman abacus may be not connected to the Chinese abacus.

Beads
The difference is that an abacus uses beads to calculate. A calculater uses solar energy or batteries to make its digital numbers. In other words an abacus uses beads and a calculater uses buttons you press to put numbers on the calculaters screen.
