There are several different structures when it comes to ethernet cables. It can also be used to hardwire devices like TVs, computers and other devices that require the internet or a network to work. The most common use for an Ethernet cable is connecting a WiFi router or modem to the internet entry port or telephone line. They plug into Ethernet ports on a variety of devices. Typically, Ethernet cables are used to provide an internet connection, connect devices to a local network.
Sometimes, internet service providers will provide different coloured leads so that it’s easy to refer to the leads by colour What Does An Ethernet Cable Do? Many computer network administrators will colour coordinate their cables so they can easily manage and maintain their networks. There is no difference between the colours of the cables. They come in a variety of different colours too. It is also possible to cut the cables to your preferred length. Sizes usually start at around 0.3 metres and can go up to 30 metres and beyond. Sometimes, the port will have an LED light in it so the Ethernet jack will light up when successfully connected.Įthernet cables can vary in length. When you push the cable into the Ethernet cable, it should click into place. They have a small lever on the top which helps secure and unclips the Ethernet cable. The connector is slightly bigger than a phone cable’s connector.Īt the end of each cable is a small modular plug, often a Registered Jack 45 (RJ45) connector. Ethernet cables have double the amount of wires to a phone cable (8 vs 4). What Do Ethernet Cables Look Like?Įthernet cables look similar to phone cables. It’s usually recommended to wire devices that do not move and use WiFi for mobile devices. Hardwiring devices has its benefits, including faster internet and more reliable connectivity. Ethernet ports can be found on routers, computers, TVs and most internet and network-enabled devices. They are designed to work with Ethernet ports. All Ethernet cable manufacturers must adhere to these strict standards to ensure quality and safety.Įthernet cables are a type of network cable. The IEEE created a written guide to Ethernet standards, and work to improve these standards as technology advances. By 1982, the Institute of Electrical and Electronics Engineers (IEEE) standardised the format, so all networking and computer devices would use the same ports. The idea of an Ethernet network is that computers and other devices can share files, information and data between each other efficiently.Įthernet was released in 1980. This is often referred to as a local area network or LAN. These cables are vital when creating a home or business network or establishing internet connections.īut what are Ethernet cables? What do they do? Why do you need them? ContentsĮthernet is a way of connecting computers and other network devices in a physical space.
They are the workhorses of the wired network world.
