Ethernet standards are a set of guidelines and specifications that define the parameters for the physical and data-link layers of the Ethernet networking technology. These standards ensure interoperability and compatibility among networking devices from different manufacturers. The standards specify characteristics such as data transfer rates, cable types, and signaling methods, allowing for consistent communication across diverse devices and networks. Examples of Ethernet standards include the widely used 10/100/1000BASE-T, defining Gigabit Ethernet over copper twisted pair cables, and 10GBASE-SR, which specifies 10 Gigabit Ethernet over short-range multimode fiber optics. Standardization is essential to create a common framework, enabling seamless integration of networking equipment and facilitating the widespread adoption and evolution of Ethernet technology over time.
