How Devices Communicate: The Role of Addresses in Computer Networks

A MAC address, short for Media Access Control address, is an integral identifier assigned to network interfaces for communications on a physical network segment. Structured as a 48-bit string, it’s conventionally displayed in six pairs of hexadecimal numbers separated by colons or hyphens—such as 00:1A:2B:3C:4D:5E. This structure is not arbitrary. The first 24 bits (three… Read More »
