Many users of computers, tablets, smartphones, routers and other networking devices are faced with a term such as MAC address. In this presentation, we’ll explain what a MAC address is, how to get a MAC address and how to change it in on a Mac operating system.

2. What does MAC address stand for?
● MAC ID (Media Access Control) is a
unique digital number assigned to
each computer on the network, more
precisely not to a computer, but to a
network card.
● The MAC address is registered on the
network card when it is created in the
factory.
● It is actually used for information
exchange between computers on
the local network.

4. Why do MAC addresses exist?
● Static IP: Routers allow you to assign static IP addresses to computers.
● MAC address filtering: networks can use MAC address filters, allowing
only devices with specific MAC addresses to connect to the network.
● Device identification: Many Wi-Fi networks at the airport and other
public Wi-Fi hotspots use the MAC address of the device to identify it.
● Device Tracking: Because the MAC ID is a unique number, it can be
used for tracking.
