The Foundation of Wired Networking: An Introduction to Ethernet
Ethernet is a family of wired computer networking technologies commonly used in local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs). It provides a standardized way for devices to communicate with each other over a physical cable, most often a twisted-pair copper cable or a fiber optic cable. Known for its reliability, speed, and security, Ethernet remains the preferred choice for connecting devices that require a stable and high-speed network connection, such as desktop computers, servers, and gaming consoles. While wireless technologies like Wi-Fi have become widespread, Ethernet continues to be the backbone of enterprise networks and high-performance home setups.
