At first glance, Ethernet cables all look the same—just long cords with plastic ends. But those different colors? They’re not random. In many homes and especially in professional networks, cable colors follow specific conventions that help technicians instantly understand what each line is doing. The color of an Ethernet cable can indicate its purpose, its network type, or even the level of access it provides.
What is an AirTag and how does it work?
An AirTag is a small tracking device designed by Apple to help you locate personal items like keys, wallets, bags, or luggage. It works seamlessly with Apple devices and integrates directly into the Find My app, making tracking simple and private.
