Connectors of computer network

We can’t just go out and get cables and expect to run network. First, we need some way of catch computer to the network via those cables. In other words, we now need to investigate connector possibilities.

The kind of computer we need depends on the kind of cable that we use. If we buy Ethernet T-connectors for future network, we’d better be prepared to go with an Ethernet network because Ethernet connectors won’t works with twisted-pair or fiber. Each kind of cables uses different connectors.

BNC Connectors:

We’ll use three kinds of connectors on an Ethernet bus network:

T-connectors:
link cable to the cards making T-Shape. The T-connector plugs into the card we’ve installed in computer. The cable connects to the crossbar of the T-connector.

BNC connectors:

Link cables together and connect them to T-connectors.

Terminators:

Terminate the LAN on either end. Terminators are made for either 50-ohm or 75-ohm cables; 50-ohm terminators are usually the standard. Pay attention when we are buying terminators because they won’t work if mix them up. Most coax network cable system needs 50-ohm terminators.

RJ-45:

Mist unstable twisted pair cable terminates using connectors that look like chunkier versions of the connectors used to plug telephone into the wall. These are called RJ-45, whereas telephone uses RJ-11 connectors.
