The communication channel defines the actual end system where the information will rest. For example, the information may need to be displayed as a graph to an end user on their laptop, it may be meant for a printer to print out, or it may be meant to be displayed at a huge billboard in a stadium. Understanding the channel of communicating the information helps you design a system that is well-suited to such channels.

The characteristics of a communication channel can be classified as:

• Ability to reach wider audience (TV shows)
• Target a specific audience (data analysts)
• Efficient use of resources (bandwidth, for example)
• Share information quickly (SMS from public health institute as soon as a fire breaks out near your home)
• And most importantly, bring the attention back on the table of the decision-makers

Let's try to bring all of this together with a real-world use case.
