2212 The OSI Layers and Protocol Stacks $49

Course 2212: OSI Layers and Protocol Stacks - Unlimited Plan

The ideas in this course allow us to relate different pieces of the puzzle together in all of the subsequent lessons and courses.

The OSI 7-Layer Reference Model is used to sort out the many functions that need to be performed, to be able to discuss separate issues separately. The functions are organized into groups called layers, which are stacked one on top of the other.

The course starts with the big picture, then one lesson for each layer, then protocol stacks.
