Ethernet is a computer LAN technology.The IEEE 802.3 standard, an organization of IEEE, sets the technical standard for Ethernet, which specifies the content of the protocols that include physical layers of wiring, electronic signals, and media access layers.Ethernet is the most widely used LAN technology, replacing other LAN standards such as token ring, FDDI, and ARCNET.
Ethernet's standard topology is the bus topology, but the current fast Ethernet (100base-t, 1000base-t) USES hubs for network connectivity and organization to minimize 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 Sense Multiple Access/Collision Detection) bus technology.Ethernet enables the idea of sending messages from multiple nodes of a radio system over a network, each of which must carry cables or channels, sometimes called Ether.(the name comes from the ether of light, a hypothetical medium of electromagnetic radiation by 19th-century physicists.Later research proved that there was no light ether.)Each node has a unique 48-bit global address -- the MAC address assigned to the network card by the manufacturer -- to ensure that all the Ethernet nodes can identify each other.Because Ethernet is so common, many manufacturers integrate Ethernet CARDS directly into computer motherboards.Ethernet communication has the characteristic of autocorrelation, which is very important for telecommunication engineering.Article provided by 10Gtek, thanks for your time.
