What is a MAC Address?
A MAC Address (Media Access Control Address) is a unique ID assigned to every network device like WiFi, Bluetooth, or LAN ports. It helps identify each device on a network.

🧩 Example:
01:32:54:76:85:AB — This is a MAC address.

The address is divided into 2 parts:

1️⃣ OUI (Organizationally Unique Identifier)

➡️ First 3 pairs (e.g., 01:32:54)
➡️ Tells which company made the device (e.g., Intel, Apple)

2️⃣ NIC (Network Interface Controller)

➡️ Last 3 pairs (e.g., 76:85:AB)
➡️ Uniquely identifies the specific device

✅ So, MAC Address = Company + Device ID
It helps the network know exactly which device is which.

📡 Without MAC addresses, your device couldn't even connect to the internet!
