Ethernet is a networking technology commonly used for local area networks (LANs) that enables devices to communicate with one another over a wired connection. It operates primarily at the data link layer of the OSI model and defines both the physical and data link layers of network communication, making it a foundational element in modern networking. Ethernet's ability to support various data rates and its role in connecting devices such as computers, printers, and switches highlight its significance in both packet forwarding and the evolution of networking technologies.
