Welcome to the Open Systems Interconnection model (OSI model) Certification Course
What is the Open Systems Interconnection Model?
The OSI Model is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system without regard to their underlying internal structure and technology.
Why do I need this certification?
Knowledge of the OSI model also makes network designs more extensible as new protocols and other network services are generally easier to add to a layered architecture.
What will I learn?
- The upper and lower layers that make up OSI
- How OSI plays a role in understanding the overall networking process

The Open Systems Interconnection model (OSI model) is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system without regard to their underlying internal structure and technology. The OSI model doesn't perform any functions in the networking process.
Upper layers of the OSI model represent software that implements network services like encryption and connection management. Lower layers of the OSI model implement more primitive, hardware-oriented functions like routing, addressing, and flow control. For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that comprise the contents of that path. The OSI model also makes network designs more extensible as new protocols and other network services are generally easier to add to a layered architecture than to a monolithic one.
