Etherneti

Etherneti is a term used in some languages to designate the Ethernet family of local area networking technologies, or to express the possessive form of Ethernet in those languages. In English, the term is not standard, but the underlying concept remains: a system of connected devices that communicate using framed data on a shared or switched network. Etherneti networks are by far the most widely deployed LAN technology worldwide.

Originating in the 1970s through collaboration among Xerox, DEC, and Intel, Ethernet was standardized as IEEE 802.3 in 1983. The standard has since evolved to support higher speeds and diverse physical media, from legacy coaxial cables to copper twisted pair and fiber optics. Modern Ethernet encompasses multiple generations and is the backbone of local networks, data centers, and campus networks.

Technology: Ethernet frames carry addressing information and a payload, with a frame structure designed to enable efficient and reliable data transfer. Early Ethernet relied on a shared medium and CSMA/CD to manage access; contemporary networks use switches to create separate collision domains and enable full-duplex operation. Physical media include copper twisted-pair cables (RJ-45 connectors) and various forms of fiber optic cabling.

Deployment and features: Ethernet supports a wide range of speeds and features, including power delivery over Ethernet (PoE) and virtual LANs (VLANs) for segmentation. It remains compatible with IP-based networking, forming the core of enterprise and consumer networks and serving as the common interconnect between LANs and WANs through routers and switches.
