Study Notes
Cable Types
- A common copper-based medium for interconnecting network devices is twisted-pair cable, consisting of four pairs of color-coded wires twisted together and encased in a flexible plastic sheath.
- STP (Shielded Twisted-Pair) cable provides better noise protection than UTP (Unshielded Twisted-Pair) cabling.
- Unshielded Twisted-Pair (UTP) cable consists of four pairs of color-coded wires twisted together and encased in a flexible plastic sheath, not five pairs.
Network Interface Card (NIC)
- The function of a Network Interface Card (NIC) is to connect devices to a network.
Cable Uses
- Straight-through cable is used to connect host to switch or router to switch.
- It is not used to connect routers to switches or hubs.
Connectors
- The main function of RJ-45 connectors is to connect devices to a network.
- RJ-45 connectors are not mainly used to connect routers to switches or hubs.
STP Cable Features
- STP cable shields the entire bundle of wires within the cable as well as the individual wire pairs.
- STP cable provides better noise protection than UTP cabling, but it does not do so at a lower price.
