Generally, computer network equipment required is:
- Network Card (LAN Card) is installed on a PC function to be able to communicate with other computers that are interconnected with the network using a Local Area Network (LAN). To connect it using a coaxial cable, twisted pair and can be used also wireless LAN.
- Hub. Shaped tool box with some holes in the back of this is the tool as a recipient of signals from a computer, then mentranmisikan to another computer that is connected in one network and the appliance is a signal booster on UTP cable.

- Connector, this tool is a device used as an interface cable mounted on the end of the cable. There are several kinds of connectors in accordance with the type of cable to be used, such as: BNC connector for coaxial cable, RJ45 connector for UTP cable types and ST connectors for fiber optic cable.
