unique identifier assigned to network interfaces for communications on the physical network segment
A MAC address is a unique identifier assigned to the network connection port on your device (like your computer or phone) that allows it to communicate with other devices on the same physical network. It matters because devices on a local network use MAC addresses to find and talk to each other, similar to how street addresses help mail carriers deliver letters to the right house.

MACアドレス（マック・アドレス、英語: Media Access Control address）とは、Media Access Controlにおいて、ネットワークインタフェースを識別するために使用される識別子である。OSI参照モデルでいえば、第2層（データリンク層）にあたる。 原則として全てのネットワーク機器に一意に割り当てられるが、様々な要因で例外が存在する。
