4. Router

   • A router is a device that transfers data packets, by the most efficient route, from one network to another i.e. between networks.

5. Cables

   • An ethernet cable is made up of a set of four 'twisted pair' copper wires enclosed in a plastic sleeve with a standard network plug on the end.
   • Fibre optic cables are made up of many glass fibres held together inside a sheath. They use light signals to transport the data, often over a long distance.

6. WAP

   • The WAP has a cable connecting it to the network hub or switch.
   • A WAP is able to pick up Wi-Fi data packets and convert them into data packets for the wired network, and also the other way around - wired data packets back into Wi-Fi packets.
