Detailed explanation-1: -Ethernet works by breaking up information being sent to or from devices, like a personal computer, into short pieces of different sized bits of information called frames. Those frames contain standardized information such as the source and destination address that helps the frame route its way through a network.
Detailed explanation-2: -Standard Ethernet cables are capable of providing both data and power so you do not need to upgrade to special cable to connect PoE devices. However, you will need to get or ‘inject’ power into your network. You can do this with a PoE hub or switch or with a small injector device.
Detailed explanation-3: -Ethernet is the traditional technology for connecting devices in a wired local area network (LAN) or wide area network (WAN). It enables devices to communicate with each other via a protocol, which is a set of rules or common network language.
Detailed explanation-4: -Ethernet ports are connected in a couple ways. The most common way to connect an ethernet port is using a patch cable. A patch cable is a copper twisted pair assembled with an RJ45 modular plug on either end. You plug one side of the cable in the port until it clips in and you do the same on the other device.
