OSI Model Layers & Data Encapsulation

COURSE DESCRIPTION

The Open Systems Interconnection, or OSI, model is used to describe how computer systems communicate with each other. Frequently used for troubleshooting network problems, the seven layers of the OSI model are concepts with which all networking professionals should be familiar.

Why should you attend?

In this course, you’ll learn about each layer of the OSI model. You’ll outline how human-readable information, such as emails and chat messages, are transferred over a network, as well as the path this information takes along the OSI model.
