To master the complexity one must apply the given points.

• CONCENTRATE IN UNDERSTANDING THE CONCEPTS:

Instead of details of wires used to connect computers to a specific network, it is important to explain a few basic categories of wiring process their disadvantages and advantages. For example: Instead of how a specific protocol operates congestion, we could concentrate on what congestion is and why it must be operated.

• LEARNING THE NETWORKING TERMINOLOGY:

The second tool for mastering the complexity is to illustrate the networking terminology. In addition to this one has to concentrate the concepts and not details, concentrate on depth and not the breath of technologies, also one would understand the illustrations and analogies  Network terminology is given with new ideas so it is much helpful to learn the methods to overcome the complexity of computer networks.
