Ethernet ( / ˈiːθərnɛt / EE-thər-net) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). [ 1] It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3. Ethernet has since been refined to support higher ...
It is immediately followed by the Ethernet frame, which starts with the destination MAC address. [ 1] In computer networking, an Ethernet frame is a data link layer protocol data unit and uses the underlying Ethernet physical layer transport mechanisms. In other words, a data unit on an Ethernet link transports an Ethernet frame as its payload.
As a result, many network architectures limit the number of repeaters used in a network, e.g., the Ethernet 5-4-3 rule. An Ethernet repeater with multiple ports is known as an Ethernet hub . In addition to reconditioning and distributing network signals, a repeater hub assists with collision detection and fault isolation for the network.
Gigabit Ethernet. Intel PRO/1000 GT PCI network interface controller. In computer networking, Gigabit Ethernet ( GbE or 1 GigE) is the term applied to transmitting Ethernet frames at a rate of a gigabit per second. The most popular variant, 1000BASE-T, is defined by the IEEE 802.3ab standard. It came into use in 1999, and has replaced Fast ...
The network controller implements the electronic circuitry required to communicate using a specific physical layer and data link layer standard such as Ethernet or Wi-Fi. [a] This provides a base for a full network protocol stack, allowing communication among computers on the same local area network (LAN) and large-scale network communications through routable protocols, such as Internet ...
Local area network. A local area network ( LAN) is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. [1] By contrast, a wide area network (WAN) not only covers a larger geographic distance, but also generally involves leased telecommunication ...
EtherNet/IP. EtherNet/IP (IP = Industrial Protocol) [ 1] is an industrial network protocol that adapts the Common Industrial Protocol (CIP) to standard Ethernet. [ 2] EtherNet/IP is one of the leading industrial protocols in the United States and is widely used in a range of industries including factory, hybrid and process.
The physical-layer specifications of the Ethernet family of computer network standards are published by the Institute of Electrical and Electronics Engineers (IEEE), which defines the electrical or optical properties and the transfer speed of the physical connection between a device and the network or between network devices.
