Network Theory
Success in networking will often depend on how well you understand the underlying network theory.
In this section, you will see basics like the OSI model, VLAN types, and ICMP. This also covers more advanced concepts like the control and data plane, HTTP protocol, and REST API’s.
Sometimes we all need to design a new network. Or maybe you manage a network that needs improvement. Understanding the concepts behind network design is a must-have!
