Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs and WANs.
The most common types are:
- Unshielded Twisted Pair (UTP) Cable
- Shielded Twisted Pair (STP) Cable
- Coaxial Cable
- Fiber Optic Cable
- Serial Cable

Types of cable Connectors
- The standard connector for unshielded twisted pair cabling is an RJ-45 connector
- The most common type of connector used with coaxial cables is the Bayone-Neill-Concelman (BNC) connector
- The most popular serial connectors are the smart serial connector and the V.35 connector
- The most popular Connector for Fiber optic cable is the Subscriber connector and the FC connectors
- Most switches use SFP Connectors to covert optical connections to copper.
