Summary: 
This course explains the Open Systems Interconnection (OSI) reference model. This model is an industry standard for increased interoperability and breaks network communication into seven distinct layers. This course also explains the purpose and function of each layer and sub-layer in detail.

Ojectives: 
After completing this course, students will be able to:
Explain the rationale behind the development of the OSI model.
Describe the differences between connection-oriented and connectionless communications
Explain the functions of each layer and sub-layer in the OSI model
Describe how the OSI model passes between network modes
Describe the five steps of encapsulation and de-encapsulation

Topics: 
Developing the OSI Reference Model
The Physical Layer and the Data Link Layer
The Network Layer and the Transport Layer
The Session, Presentation, and Application Layers
The OSI Model in Operation
The Data Encapsulation Process
Reversing the Data Encapsulation Process
