Every device's network adapter, whether wired or wireless, has a unique MAC address to identify itself on the networks it connects to.

Various names, including physical address, hardware address, Ethernet address, WiFi address, and more may refer to MAC addresses.
For example, a MAC address can be written in this format: a5:34:c5:41:g4:74. a MAC address can also be represented using dash (-) or dot (.) formats, such as a5-34-c5-41-g4-74 or a534.c541.g474.
