This article is to share with you about what Ethernet means. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Ethernet is a kind of computer local area network technology, which is the most common computer network in the real world. The standard topology of Ethernet is bus topology, but the current Fast Ethernet uses switches for network connection and organization in order to reduce conflicts and maximize network speed and efficiency.

Ethernet is a kind of computer local area network technology. The IEEE 802.3 standard of IEEE establishes the technical standard of Ethernet, which specifies the content of physical layer connection, electronic signal and media access layer protocol. Ethernet is the most widely used LAN technology at present, replacing other LAN technologies such as token Ring, FDDI and ARCNET.

Ethernet is the most common computer network in the real world. There are two types of Ethernet: the first is classical Ethernet and the second is switched Ethernet, which uses a device called a switch to connect different computers. Classical Ethernet is the original form of Ethernet, with operating speeds ranging from 3 to 10 Mbps, while switched Ethernet is a widely used Ethernet that can run at high rates like 100,100 and 10000Mbps, in the form of Fast Ethernet, Gigabit Ethernet and 10 Gigabit Ethernet, respectively.

The standard topology of Ethernet is bus topology, but the current Fast Ethernet (100BASE-T, 1000BASE-T) uses switches for network connection and organization in order to reduce conflicts and maximize network speed and efficiency. In this way, the Ethernet topology becomes a star; but logically, Ethernet still uses bus topology and CSMA/CD (carrier multiple access / collision detection) bus technology.

Ethernet realizes the idea of sending information by multiple nodes of the radio system on the network, and each node must obtain the 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 light etheric does not exist. Each node has a globally unique 48-bit address, that is, the MAC address assigned to the network card by the manufacturer, to ensure that all nodes on the Ethernet can identify each other. Because Ethernet is so common, many manufacturers integrate Ethernet cards directly into the computer motherboard.
