This article mainly shows you "the technical specification of what Ethernet is dedicated to in computers". The content is simple and clear, and I hope it can help you solve your doubts. Let me lead you to study and learn this article "what is Ethernet used exclusively for in computers?"

Ethernet is a technical specification dedicated to "local area network". Ethernet is a kind of networking technology of computer local area network, and it is the most general communication protocol standard adopted by local area network, which defines the cable type and signal processing method used in local area network (LAN).

The operating environment of this tutorial: windows7 system, Dell G3 computer.

Ethernet technology refers to the baseband LAN specification created by Xerox and jointly developed by Xerox,Intel and DEC. Ethernet networks use CSMA/CD (Carrier sense multiple access and collision Detection) technology and run on many types of cables at 10M/S rates. Ethernet is similar to the IEEE802 3 series standards. Ethernet is not a specific network, but a technical specification.

Ethernet is the most general communication protocol standard used in the existing local area network. The standard defines the cable types and signal processing methods used in the local area network (LAN). Ethernet transmits packets between interconnected devices at the rate of 10~100Mbps. Twisted pair cable 10 Base T Ethernet has become the most widely used Ethernet technology because of its low cost, high reliability and 10Mbps speed. Direct spread spectrum wireless Ethernet can reach 11Mbps, and the products provided by many manufacturing suppliers can communicate with common software protocols, and the openness is the best.

Ethernet (Ethernet) is a kind of computer local area network technology. The IEEE 802.3 standard made by IEEE gives the technical standard of Ethernet. It specifies the contents of the physical layer wiring, electrical signals, and media access layer protocols. Ethernet is the most widely used LAN technology at present. It largely replaces other LAN standards, such as token Ring Network (token ring), FDDI and ARCNET.

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

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

The above is all the contents of the article "what are the technical specifications for Ethernet in computers?" Thank you for reading!
