MAC addresses work with the card in your device that lets it connect wirelessly to the internet, called a Network Interface Controller (NIC). MAC addresses are used to identify which device is which on your local network so that data gets sent to your computer and not your roommate's smartphone.
A MAC address (media access control address) is a 12-digit hexadecimal number assigned to each device connected to the network. Primarily specified as a unique identifier during device manufacturing, the MAC address is often found on a device's network interface card (NIC).
A MAC address (short for medium access control address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment.

The MAC address is a 12 digit hexadecimal number that is most often displayed with a colon or hypen separating every two digits (an octet), making it easier to read. Example: A MAC address of 2c549188c9e3 is typically displayed as 2C:54:91:88:C9:E3 or 2c-54-91-88-c9-e3.
MAC Addresses are unique 48-bit hardware numbers of a computer that are embedded into a network card (known as a Network Interface Card) during manufacturing. The MAC Address is also known as the Physical Address of a network device. In the IEEE 802 standard, the data link layer is divided into two sublayers:
A MAC address is a hardware identification number that uniquely identifies each device on a network. Every network interface card, such as an Ethernet card or a Wi-Fi adapter, has a permanent MAC address assigned by its manufacturer; some operating systems allow an adapter's MAC address to be temporarily changed, or "spoofed," in software.
