MAC may refer to any of the following:

Mac address

1. Short for medium access control, or MAC address. Known as a physical address and hardware address whose number is uniquely formatted in hexadecimal format and given to each computer or network device on a computer network. The addresses are usually assigned by the hardware manufacturer, and these ID's are considered burned into the firmware of the network access hardware. Because of this process, some vendors use specific formats in the hardware address. Below is an example of a MAC address.

D4-BE-D9-8D-46-9A

Because a MAC address is a unique address, devices on a network do not share the same MAC address.

Note

Because of the potential of tracking wireless devices using a MAC address, many manufacturers (e.g., Apple, Google, and Microsoft) generate random MAC addresses.

2. A Mac is also an abbreviation used to describe Macintosh, a line of personal computers created by Apple.
