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.
Objectives:
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
