An Abacus has beads and strings.
ABACUS is a name of a calculating apparatus - it is not an acronym.
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.

An abacus is not a computer system as zero parts of the abacus are electrical. For the abacus to be a computer system, it has to have an input, output and process and store data. If even one of the following is not true then the device will not be considered a computer system. An abacus can not store data, as the human using the abacus will have to memorise the sequences instead of the abacus being able to memorise on its own.
