MAC Address

Overview

Every device that connects to a network has a MAC address (Media Access Control address) configured on its Network Adapter. This is the unique sequence of numbers and letters that is the foundational identity of that device on the network. Networked devices talk to each other with this address, but it is really difficult to read and remember and that is why we have things like DNS, IP, and DHCP all of which combine to make easy to remember ways to refer to computers and other network devices.
