Open Systems Interconnection (OSI) Model

Length: 00:07:59

Lesson Summary:

The Open Systems Interconnection Model is a standard that describes how networking interacts with user applications. It starts with the physical layer (i.e. cabling), and proceeds to the application layer where users interact with applications (i.e. web browsers or email clients). This lesson reviews the layers of the OSI Model and describes what functions, protocols, and devices function at each layer.
