What is local area network and ring topology?

Answer 1

A Local Area Network (LAN) may use many different types of topologies (how the network is physically wired). If one uses a ring topology, then a special type of managed hub is usually used which implements packet switching in a round, ring structure, in which each station is visited by the packet in linear sequence.

Ring topologies also involve the use of a 'token', which describes whether a station on the ring may use the network or not.

Ring topology can be considered as a LAN and it is rarely used nowadays.
