An Ethernet cable is a common type of network cable used with wired networks. Ethernet cables connect devices such as PCs, routers, and switches within a local area network.
These physical cables are limited by length and durability. If a network cable is too long or of poor quality, it won’t carry a good network signal. These limits are one reason there are different types of Ethernet cables that are optimized to perform certain tasks in specific situations.
An Ethernet cable resembles a traditional phone cable but is larger and has more wires. Both cables share a similar shape and plug, but an Ethernet cable has eight wires, while phone cables have four. Ethernet cable connectors are also larger.
