This NIC comes as a Wi-Fi adapter, an Ethernet adapter (wired), or a cellular modem.Ī MAC address consists of six groups of two characters (numbers or letters). Your device - be it a computer, a tablet, or a phone - can connect to the Internet because it has a NIC. So a MAC address - I’ll call it MAC from now on for short - is precisely that, the unique identifier to control the access of a network interface controller (NIC), which we often call a network adapter.
