Ethernet cable was commercially introduced in 1980. The Institute of Electrical and Electronics Engineers (IEEE) had standardized the format so that all networking and computing devices could use the same port.
Ethernet cable is a common type of networking cable used in wired networks. Ethernet cables connect devices such as computers, routers, and switches to the local network. It provides a convenient interface for connecting multiple devices such as computers, routers, and switches. With one router and multiple Ethernet cables, you can create a local area network that allows all connected devices to communicate with each other.
It is designed to work with Ethernet ports. Ethernet ports can be found on routers, computers, televisions, and most devices with Internet and network connections. You can buy different types of Ethernet cables. Most of these cables are provided free of charge through equipment or other means using an Ethernet connection.
The idea behind Ethernet is that computers and other devices can efficiently exchange files, information, and data with each other.
An Ethernet port is also called a plug or receptacle. This is the hole in the computer networking equipment that the Ethernet cables connect to. It connects wired network equipment to an Ethernet local area network, metropolitan area network (MAN), or wide area network (WAN). An Ethernet port is commonly found on network devices, including computers, routers, game consoles, etc.
The primary function of the Ethernet port is to create an Ethernet connection. Ports are essential because they only allow the designated device to see this data, not everyone connected to the switch. The switches use Ethernet ports. Your router is a switch that allows it to communicate with other connected devices.
Ethernet connections can be created between computers, servers, switches, hubs, routers, modems, game consoles, printers, and more. When multiple devices are connected, it is called LAN (local area network), WAN (wide area network), or MAN (metropolitan area networks).
The port stores the MAC address of the device, so when it receives only a specific address, it can send it to the port that matches the correct MAC address. Thus, no other device sees the data, unlike a hub, which broadcasts the received data to each connected device
