Let’s talk the OSI Model, or the Open Systems Interconnect Model.

Cloudflare describes the OSI Model pretty well: “The open systems interconnection (OSI) model is a conceptual model created by the International Organization for Standardization which enables diverse communication systems to communicate using standard protocols. In plain English, the OSI provides a standard for different computer systems to be able to communicate with each other.

The OSI Model can be seen as a universal language for computer networking. It’s based on the concept of splitting up a communication system into seven abstract layers, each one stacked upon the last.”

The OSI Model is made up of 7 layers. It’s split in this way in order to describe the compartmentalization of the job of each of the layers of networking. The layers thus can stay self-contained in their design and implementation and are not closely coupled with any of the other layers in principle.

The top layer is the level 7 layer which corresponds to the Application Layer. This layer essentially supports end-user applications and processes, so it’s also called the end user layer.

This layer is the one that is closest to the end user. Technologies part of the level 7 layer include…
