MAC Address Explained | CCNA 200-301 | NG Cloud Networks
Have you ever wondered how devices communicate within a LAN even before an IP address comes into play?
In this lesson, we'll explore one of the most important concepts in networking—the MAC Address. You'll learn how every network interface is uniquely identified, how switches use MAC addresses to forward frames, and why understanding MAC addresses is essential for every Network Engineer.
By the end of this video, you'll clearly understand:
🔹 What is a MAC Address?
🔹 MAC Address Structure (48-bit Address)
🔹 OUI (Organizationally Unique Identifier)
🔹 Device Identifier
🔹 Unicast, Multicast & Broadcast MAC Addresses
🔹 Universally vs Locally Administered MAC Addresses
🔹 Real-world examples used in enterprise networks
