MAC Address

A MAC address (Media Access Control address) is a unique identifier assigned to a device that connects to a network, like a computer, smartphone, or smart TV. It’s built into the device’s network hardware.

Think of it like a Social Security number for your device—it’s a one-of-a-kind ID that helps networks recognize and communicate with it. If your home Wi-Fi is like a nightclub, the MAC address is the VIP pass that tells the bouncer (your router) which devices are allowed in and where to send the data.
