An Ethernet cable is a type of network cable used for high-speed wired network connections between two devices such as computers and routers on IP networks. Ethernet is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN), and wide area networks (WAN) . Ethernet cables are designed to work with Ethernet ports, which can be found on routers, computers, TVs, and most internet and network-enabled devices. They are the backbone of any computer network and are vital when creating a home or business network or establishing internet connections. Ethernet cables are used to provide an internet connection and connect devices to a local network. They plug into Ethernet ports on a variety of devices. Ethernet cables are wires that physically connect your computer to a router or modem, giving your device access to the local area network (LAN) and internet access. Ethernet cables come in a range of lengths and colors, but both sides of the cord are the same, regardless of the brand of cable or device youre hardwiring. Ethernet cables are almost always faster than Wi-Fi connections and are usually more stable.
