Not quite. There are three main types, and you’ll already be aware that things like an Ethernet cable are shaped very differently to what you charge a phone with. The three main types are: Fiber Optic: Transmits data in the form of light. The preferred method for fast internet connections. Coaxial Cable: Carries signals at a high frequency, with a central core conductor surrounded by an insulator. Used for things such as Foxtel and digital phone networks. Twisted Pair: Two copper core wires, twisted throughout the cable. Tends to only work well over shorter distances.
