Ethernet is a technical specification dedicated to "local area networks". Ethernet is a computer local area network networking technology and the most common communication protocol standard used in local area networks; the standard defines the cable types and signal processing methods used in local area networks (LAN).

What is the technical specification for what Ethernet is designed for?

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

Ethernet technology refers to the baseband LAN specification created by Xerox Corporation and jointly developed by Xerox, Intel and DEC Corporation. Ethernet uses CSMA/CD (Carrier Sense Multiple Access and Collision Detection) technology and runs on multiple types of cables at a rate of 10M/S. Ethernet is similar to the IEEE802·3 series of standards. Ethernet is not a specific network, but a technical specification.

Ethernet is the most common communication protocol standard used in existing local area networks today. This standard defines the cable types and signal processing methods used in local area networks (LANs). Ethernet transmits information packets between interconnected devices at a rate of 10~100Mbps. Twisted pair cable 10 Base T Ethernet has become the most widely used Ethernet technology due to its low cost, high reliability and 10Mbps rate. . The direct expansion wireless Ethernet can reach 11Mbps, and the products provided by many manufacturing suppliers can use common software protocols for communication, with the best openness.

Ethernet is a computer LAN networking technology. The IEEE 802.3 standard formulated by IEEE provides the technical standard for Ethernet. It specifies the content including physical layer wiring, electrical signals and media access layer protocols. Ethernet is currently the most commonly used LAN technology. It largely replaces other LAN standards such as token ring, FDDI and ARCNET.

The standard topology of Ethernet is a bus topology, but the current Fast Ethernet (100BASE-T, 1000BASE-T standards) in order to minimize conflicts and maximize network speed and efficiency, Using a switch hub for network connection and organization, the Ethernet topology becomes a star, but logically, Ethernet still uses a bus topology and CSMA/CD (Carrier Sense Multiple Access/Collision Detect That is, carrier sense multiple access with collision detection) bus contention technology.

Ethernet is based on the idea of ​​multiple nodes of a radio system on the network sending information. Each node must obtain a cable or channel to transmit information, sometimes also called Ether. (The name comes from the electromagnetic radiation medium hypothesized by 19th-century physicists - optical ether. Later research proved that optical ether does not exist.) Each node has a globally unique 48-bit address, which is the MAC address assigned to the network card by the manufacturer. , to ensure that all systems on the Ethernet can identify each other. [3] Because Ethernet is so common, many manufacturers integrate Ethernet cards directly into computer motherboards. It has been found that Ethernet communication has the characteristics of autocorrelation, which is very important for telecommunications communication engineering.
