Is Ethernet wired or wireless?

Ethernet is a wired network technology. Each version of Ethernet has a maximum length limit of the cable (that is, the length without amplification). Signals within this range can propagate normally. Signals exceeding this range will not be spread.

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 10Mbps; Switched Ethernet is a widely used Ethernet that can run at high rates of 100, 1000 and 10000Mbps, respectively, with Fast Ethernet , Gigabit Ethernet and 10 Gigabit Ethernet.

The standard topology of Ethernet is a bus topology, but the current Fast Ethernet (100BASE-T, 1000BASE-T standards) uses 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.
