Ethernet is a wired networking technology that allows devices to communicate within a local area network (LAN) using physical cables.

Elaboration:

• Operates at Layer 2 (Data Link Layer) and Layer 1 (Physical Layer) of the OSI model.
• Faster and more stable than Wi-Fi, with speeds up to 100 Gbps in modern networks.
• Uses RJ-45 connectors and cables like Cat5e, Cat6, and Cat7.

Example:

A desktop computer is connected to a router using an Ethernet cable for a stable internet connection.
