Ethernet works by sending data packets between devices on a network using a coaxial cable or twisted pair wire. The data packets are sent over the cable using a series of electrical signals, and each device on the network has a unique address called a MAC (Media Access Control) address that is used to identify it.
Ethernet has several different versions, or standards, that define the speed and other technical characteristics of the network. The most commonly used standard is Ethernet 802.3, which defines the physical and data link layers of the OSI (Open Systems Interconnection) model. Other standards, such as Ethernet 802.1 and Ethernet 802.11, define different aspects of networking, such as network management and wireless networking.
Ethernet is known for its high speed and reliability, and it is widely used in both wired and wireless networks. It is also easy to install and configure, making it a popular choice for networking in many different environments.
