CAT 5e is the most common cabling category used today, though CAT 6 is gaining in popularity.

Token Ring networks use a star physical topology and a ring signal topology.

In bus topology, the computers are connected to the network via a main line. The cable must be terminated at both ends to prevent signal reflection.

Topology is the term used to describe the interconnectivity of network components.

The aptly named ring topology connects nodes with a central ring of cable.

Mesh is for the most part unque to wireless networks.

RG-59 is a type of coaxial cable.

The coaxial cables have an Ohm rating. RG-59 and RG-6 both are rated at 75 Ohms.

Of the alternatives, given, only the LC connector is designed for duplex fiber-optic.

Of the choices listed, only star topology has any fault tolerance
