Concept - Mac Address Mac Address is an acronym for Media Access Control Address and means the media access control address in various computer operating systems (except for the mac operating system). It is one of the basic addresses and numbers for connecting any smart device of any kind to the Internet.
And to simplify things more, the Mac Address allows you to control many things, the most important of which is the ability to access the Internet in your network and to track the activities of each user and their location on an ongoing basis.
And it is considered one of the most dangerous numbers when it comes to protecting Internet devices on a single network, such as public networks and work networks, is the Mac Address, through which the network manager can control a lot of things and track all your activities on the Internet, including, of course, shopping activities and the use of prepaid cards.
The Mac Address is a unique number for each device and is responsible for identification on the network. It is specially designed for all network cards such as Ethernet and Wi-Fi cards.
