When a device sends data on a network, it can do so in several different ways depending on the communication method. This episode covers the three major transmission types: unicast, multicast, and broadcast. You’ll learn how each method distributes data to recipients and what scenarios are best suited for each.

We'll also discuss how switches and routers handle each of these traffic types and how multicast protocols like IGMP help optimize delivery. Understanding these methods is essential for network planning and troubleshooting, especially when dealing with video streaming, discovery protocols, or flooding issues.
