Introduction To Data Transmission
Routable protocols enable the transmission of data between computers in different segments of a network. However, high volumes of certain kinds of network traffic can affect network efficiency because they slow down transmission speed. The amount of network traffic generated varies with the 3 types of data transmissions:
We are going to have a look at each one of these data transmissions because it’s very important to know the type of traffic they generate, what they are used for and why they exist on the network.

Before we proceed, please note that understanding the OSI Model (especially Layer 2 and 3), Ethernet and the way a packet is structured is fundamental to understanding a broadcast, multicast or unicast.
