Final answer:
the correct options that are characteristics of a logical ring topology are: (a) Some technologies use a token, (b) one technology uses an MAU, and (c) it's used by FDDI.
Step-by-step explanation:
The subject of this question is network topologies within the realm of Computers and Technology. When discussing a logical ring topology, there are several characteristics that can be attributed to it:
- (a) Some technologies use a token. This refers to token ring or token-passing networks, where a token, a small data packet, is passed around the network and only the machine holding the token can send data.
- (b) One technology uses an MAU (Multistation Access Unit). This is specific to IBM's token ring technology, which utilizes an MAU for network organization.
- (c) It's used by FDDI (Fiber Distributed Data Interface), which is a standard for transmitting data on optical fiber cables in a local area network.
- (d) It's not commonly used by Ethernet. Traditional Ethernet uses bus or star topologies, though there are some ring-like setups such as 'resilient packet rings.'
- (e) It's not the most popular logical technology currently. The star topology often holds this distinction, especially with modern Ethernet implementations.
In conclusion, the correct options that are characteristics of a logical ring topology are: (a) Some technologies use a token, (b) one technology uses an MAU, and (c) it's used by FDDI.
