Network connectors and other network components

Let’s have a brief look at network connectors.

Network connectors allow wired network media (coaxial cable, twisted pair, fiber optic, and so on) to connect to a network such as hubs, switches, routers, controllers, PCs, and other devices in a network. They are used to terminate a segment of network cable.
