What two types of abaci were directly derived from the Chinese abacus?

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.

What is ABACUS machine?
An abacus is a mechanical device for performing arithmetical calculations. Abaci are usually a wooden frame with beads used to represent numbers.
Is the abacus an old version of the calculator?
Yes, abacuses (or is it abaci?) were used to calculate simple maths problems.
What do you use the abacus for in today's society?
The same as it has been used for thousands of years: doing calculations. An expert abacus operator can visualise numbers and do calculations (usually) faster than someone with an electronic calculator - using an abacus visualised in their head, a skilled operator can often do calculations faster than with a physical abacus. Abaci have the advantage that the batteries don't wear out (as there aren't any), which makes their use in places with limited supply of power preferable.
Who is Fabonacci?
This is probably a mistake for Fibonacci. Fibonacci was an early Italian mathematician who promoted the use of the Hindu-Arabic numbers (those we use today) in his book Liber Abaci (1202). See Wikipedia for more information.
Who was educated during the Middle Ages?
Education was different in the Byzantine Empire and Western Europe. The East Roman Empire had started both a primary schools system and more advanced schools, including the University of Constantinople, in the year 425. The Byzantine Empire, as a continuation of the Roman Empire, continued operating these schools through the entire Middle Ages. The primary schools were run at the village level, and are said to have educated both boys and girls, with the result that many people, quite possibly a majority, were literate. In the West, the decline of the Roman Empire was destructive to educational systems. As a result, the history of education was more complicated in the West than in the Byzantine Empire. During the entire medieval period, many wealthy people were educated at home, by private tutors. There were also schools, and most, but not all, were run by the Church. Most education was in Latin, but much was in vernacular languages, especially as the Middle Ages wore on, a trend that can be seen with the development of secular literature, which was rarely in Latin. Maybe for convenience we could break the history of education in Western Europe in the Middle Ages into three time periods that are not traditional: Medieval Period I (MPI) the time from the death of Theodosius I to the reign of Charlemagne (395-768 AD), Medieval Period II (MPII) from Charlemagne to the opening of the first universities (768-1088 AD), and Medieval Period III (MPIII), the period of 1088 to 1453. MPI was characterized by a general breakdown of literacy that had actually begun during the third century AD and been exacerbated by the fall of the Roman Empire of the West, about 476 AD. The recovery from the worst of those times was slow. The Germanic law and customs that replaced Roman law in much of the area of the old empire were maintained by memorization, and little respect was provided by people accustomed to such education for those who needed to record their thoughts in writing. Written law was maintained in those areas that still operated under Roman law, and other writing was done only by the Church in most areas. During this time, education that included literacy was nearly always provided by the Church. Nevertheless, there were schools that remained open from the times of the Roman Empire, such as Cor Tewdws in Wales, which was opened before Theodosius died in 395 and closed by the English King Henry VIII. Also, there was a system of primary schools opened by the Byzantine Empire starting in 425 AD, and continued until 1453. (see the link below for Cor Tewdws and the link on the history of schools). More schools were beginning to open with increasing frequency as the sixth and seventh century wore on. In fact there are six schools currently operating in the UK that date to this period. One of these, Beverley Grammar School, was supported by the state, and was, for a period of decades, supported by Vikings, as the area it was in was part of the Danelaw. (see link below to List of the oldest schools in the world) MPII started when Charlemagne became king of France and Emperor of the West. One of the things he did was to send far and wide for scholars to educate the people of his court. (see link below for Charlemagne's policies on education) Alfred the Great repeated this in England, making sure that education was available in English, instead of Latin which was the language of the Church. He saw to it that great books were translated into English, stating as a goal that education be available to all freeborn men who were capable of being educated. (see link below for Alfred the Great's educational policies) The effect was a further spreading of education, and education being available to more people. Seven current UK schools date to this period, and at least an additional seven in Denmark, Germany, Iceland, and Sweden. (see link below to the list of the oldest schools in the world) In MPIII, beginning in 1088, many more schools were founded, and with them came the great universities. The number of these opening during the Middle Ages is truly impressive, and reflects a need for education in the wealthier members of the middle class, among such people as secular lawyers, physicians, merchants, sailors, military people, bankers, and so on. Although there were only four universities that opened in England, and two of these closed, three universities opened in Scotland, and Europe had a total of nearly sixty during this period. (see links below on universities) Many more traditional primary and secondary schools were opening during this time. And also, from the 13th century on, schools sprang up that were oriented toward teaching the things most needed for commerce. These included arithmetic using the Arabic numerals that had recently been introduced and reading and writing in the vernacular language. Theses schools were called Abacus Schools.

Who created abacus?
China Answer: The abacus has a history going back to 2500 BCE when it was first used in Sumeria.Later and improved versions were in use in Babylonia, Egypt, Persia, India, China, Rome and Greece. There are reports of abaci in India as early as the 1st century CE. The first use of Chinese abacus is not documented until the 14th Century CE although there is evidence in Chinese illustrations that they were in common use as early as 1100 CE. It was similar to the modern abacus. From China the abacus spread into Japan and Korea.Some scholars point to an independent development of the abacus in Mesoamerica by the Mayans and Aztecs. These were of course based on the base 20 not 10 as in Asia and Europe.
Why did early traders use the abacus?
They didn't have electronic calculators. Abacuses (or is it abaci? no clue... oh well...) are calculators, and they could use them to calculate things.
What makes the Chinese classic abacus the type of abacus most referred as ancestor of the digital computer?
The answer to the question may lie in the fact that the Chinese classic abacus has two heaven beads and five earth beads along each rod, and thus that makes the difference from other types of abaci. "The Chinese abacus is commonly used for working in decimal, but it may be used as well for hexadecimal numbers. Note that when all beads along a rod are set then the sum of bead values would exactly be equal to 15 or F. Hexadecimal numerals are widely used by computer system designers and programmers because they provide a human-friendly representation of binary-coded values."
