Size and weight
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.
ABACUS - Abundant Beads, Addition and Calculation Utility System

Abacus's advantage is improving mental calculations whereas its size and weight are its disadvantages.
Well, honey, the only disadvantage of an abacus is that it's as old as dirt. I mean, who even uses those things anymore? It's like trying to compete in a marathon wearing wooden clogs - sure, it can get the job done, but there are way better options out there. So, unless you're feeling nostalgic for ancient math tools, I'd say it's time to upgrade to a calculator.
One disadvantage of using an abacus is that it requires significant manual dexterity and mental concentration, which can be challenging for some users, especially beginners. Additionally, the abacus has limitations in handling complex calculations or large numbers compared to modern electronic calculators and computers. Furthermore, it lacks the ability to store calculations, necessitating a complete recall of previous steps, which can be cumbersome in lengthy computations.
One disadvantage of using an abacus is that it may be slower than using modern electronic calculators for complex arithmetic operations. Additionally, the physical manipulation of beads on the abacus can be cumbersome and may lead to errors in calculation, especially for those who are not proficient in its use. Lastly, the abacus may not be as versatile as electronic calculators in performing advanced mathematical functions or storing and recalling previous calculations.
