OSI Layers and Internet Protocol Suite
Course Overview The OSI 7-Layer Reference Model, which identifies and divides the functions to be performed into groups called layers. This framework is required to many functions that need to be performed, to discuss separate issues separately. First, we’ll define what is “protocol” and compare that to a standard. Then we’ll define what is “layer” and how a layered architecture operates, and provide an overview of the name, purpose and function of each of the seven layers in the OSI model. Then, with one lesson for each of the layers, examining in detail the functions that have to be performed and giving examples of protocols and how and where they are used to implement particular layers.
The result is a protocol stack, one protocol on top of another on top of another to fulfil all of the required functions. On completion of this course, you will be able to define a protocol and differentiate that from a standard, explain why a layered architecture is required, list the seven layers of the OSI model, the name, purpose and functions of each one, and explain how a protocol stack operates and where the protocol headers are located.
