However, before we discuss them in detail, let’s start by looking at the Open System Interconnection (OSI) model that defines a significant portion of how protocols operate.

Introducing the OSI model

The OSI model is a framework for establishing a common method of communication between systems. The basic structure is illustrated in the following figure:

When the receiver gets the data, the process follows the order from layer...
