What is the primary function of Ethernet in networking?

The primary function of Ethernet in networking is to allow devices to communicate over a local area network (LAN). Ethernet is a widely used networking technology that defines how data packets are formatted, transmitted, and received within a local network. It operates at the data link layer of the OSI model and outlines the physical and data link layers for connecting devices such as computers, printers, and servers within close proximity to each other.

Ethernet facilitates reliable communication among connected devices by using a common protocol that ensures data is sent and received efficiently. It supports different speeds and can use either coaxial cables or twisted pair wiring to transmit data, making it adaptable to various networking environments.

This capability to connect multiple devices within a localized area is what fundamentally defines Ethernet's role in networking, making it essential for creating effective and functional LANs.
