What is Ethernet?
Ethernet is a computer local area network technology. The IEEE 802.3 standard of the IEEE organization establishes the technical standard of Ethernet, which specifies the contents including the physical layer connection, electronic signals and media access layer protocols. Ethernet is currently the most commonly used LAN technology, replacing other LAN technologies such as Token Ring, FDDI, and ARCNET.
Ethernet is the most common type of computer network in the real world. There are two types of Ethernet: the first is classic Ethernet and the second is switched Ethernet, which uses a device called a switch to connect different computers. Classic Ethernet is the original form of Ethernet, with operating speeds ranging from 3 to 10 Mbps. Switched Ethernet is a widely used Ethernet that can run at high speeds such as 100, 1000, and 10000 Mbps, respectively, with fast Ethernet. Network, Gigabit Ethernet and 10 Gigabit Ethernet.
What is Ethernet Switch?
Ethernet switch is a switch based on Ethernet to transmit data. Ethernet uses a local area network with a shared bus transmission medium. The structure of the Ethernet switch is that each port is directly connected to the host, and generally works in full duplex mode. The switch can communicate with many pairs of ports at the same time, so that each pair of hosts communicating with each other can transfer data without conflicts like an exclusive communication medium.
The Apllication of Ethernet Switch
Ethernet switches are most commonly used, and they are cheaper and complete. Therefore, the application fields are very wide, and they can be seen in large and small local area networks. Ethernet switches usually have several to dozens of ports, which is essentially a multi-port bridge. In addition, its port speed can be different, and its working mode can also be different. For example, it can provide 10M, 100M bandwidth, half-duplex, full-duplex, adaptive working mode, etc.
