Understanding MAC Addresses: Key for Network Management

A Media Access Control (MAC) address is a unique identifier assigned to a network interface for communication on the physical network segment. It consists of six groups of two hexadecimal digits, usually separated by colons or hyphens. Each MAC address is unique to the device, allowing for accurate identification on a local network.

Real-Life Examples
