Ethernet
An Ethernet is a wired data network that connects hardware/software. In most cases, the connection is established via a LAN cable, which is why an Ethernet is also referred to as LAN technology. The Ethernet enables end devices to exchange data with each other. End devices include, for example, printers, servers, computers, etc. These interconnected devices form a local network that sends data packets back and forth between the individual devices via the so-called Ethernet protocol. The protocol that is currently most commonly used is the IEEE 802.3. protocol. In earlier times, up to 3 megabits per second could be transmitted with the Ethernet protocol, whereas nowadays up to 1000 megabits per second are possible.
