Ethernet

Ethernet is a way that computers, and other devices, talk to each other and connect to the internet. The cables are sometimes called "Ethernet cables", Cat 5 cables, RJ45 or "network cables".

It looks similar to the cable you use to hook up a telephone, but it is a slightly different shape. There's a little piece of springy plastic on the top. This holds it in the socket.

Ethernet net cables are used to connect devices to a router in order to connect to the internet. You can use with some cordless phones and videophones.
