What are the 4 layers of the TCP IP model?

The TCP IP model is a four-layer communication model that breaks down communication into manageable chunks. This makes it possible to standardize the process of communication without relying on software and hardware providers. As a result, companies can save time and money while still ensuring reliable communication. This post will look into all 4 layers of the TCP IP model in depth.

I would suggest you read about the OSI model, OSI model cheat sheet Infographic, IP subnetting, VLANs, and VLAN tagged vs. untagged topics to grasp the basic understanding of networking.

TCP/IP protocol suite

TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP is also used as a communications protocol in a private computer network (an intranet or extranet).

The entire IP suite -- a set of rules and procedures -- is commonly referred to as TCP/IP. TCP and IP are the two main protocols, though others are included in the suite.

What is TCP/IP Encapsulation? by Eugene Blanchard

This video provides a visual introduction to the what happens to information as it moves down through the TCP/IP network protocol stack. It was made using the trial version of excellent animation/presentation tool called VideoScribe.
