What is the topology of Ethernet

The topology of Ethernet is "bus type"; the topology used by Ethernet is basically bus type. The bus topology uses a single cable trunk as a public transmission medium, and connects the network through corresponding hardware interfaces and cables. All computers are connected directly to a shared bus; the bus topology is required to ensure that there are no conflicts when data is eventually sent.

What is the topology of Ethernet?

The topology of Ethernet is "bus type".

The topology used by Ethernet is basically bus type. The bus topology uses a single cable trunk as a public transmission medium, and all computers in the network are directly connected to the shared bus through corresponding hardware interfaces and cables; bus topology Need to ensure that there are no conflicts when the data is finally sent.

Ethernet is the most common 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, operating at speeds ranging from 3 to 10 Mbps; Switched Ethernet is a widely used Ethernet that can run at high rates of 100, 1000 and 10000 Mbps, respectively, with Fast Ethernet Network, Gigabit Ethernet and 10 Gigabit Ethernet.

The standard topology of Ethernet is bus topology, but Fast Ethernet (100BASE-T, 1000BASE-T standards) will improve network speed and efficiency in order to reduce conflicts. Maximize, use switches for network connectivity and organization. As a result, the topology of Ethernet becomes a star; but logically, Ethernet still uses bus topology and CSMA/CD (Carrier Sense Multiple Access/Collision Detection). bus technology.

Ethernet realizes 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 nodes on the Ethernet can identify each other. Because Ethernet is so common, many manufacturers integrate Ethernet cards directly into computer motherboards.
