This answer is correct, however; in the 5th edition the answer is in Chapter 4 on page 162.
The domain is the highest taxonomic rank that contains one or more kingdoms. The domain is above the kingdom in the hierarchy of biological classification.
The box labeled "a" represents the domain level in biological classification. It is the highest level in the classification hierarchy.
A Domain.
The current hierarchy of classification is: domain, kingdom, phylum, class, order, family, genus, species.
A collision domain is an area on the network where two devices may attempt to transmit at the same time. A hub has 1 collision domain overall. A switch has 1 collision domain per interface. The fewer devices in 1 collision domain, the better. ----
AnswerYes. You can't split a broadcast domain without also splitting the collision domain. The only devices that can split a broadcast domain are routers and layer 3 switches. Switches, bridges, and routers can all be used to split the collision domain. Hubs and repeaters do not split the collision domain or the broadcast domain.
In biology, a kingdom is a subsection of a domain. Thus, domains are bigger than kingdoms; they are in fact the highest subdivision of biological life in general. In other usage, a domain - sometimes demesne is used as a synonym - refers to the Area controlled by a group or an individual. As such, a domain would almost always be smaller than a kingdom, but kingdoms themselves are the domain of a king, and in that case would make neither larger than the other.
Domain names are managed under a hierarchy headed by the Internet Assigned Numbers Authority (IANA),
Rank is the relative position in a taxonomic hierarchy. The rank above kingdom is domain. The rank above domain is life.
Domain Kingdom Phylum Class Order Family Genus Species
A switch or router will limit the number of clients in a collision domain, thus limiting what can be in the collision domain.
Broadcast.
