Description
Layer 1 Physical Layer Overview Our first lesson of the Cybrary CCNA course focuses on Layer 1 of the OSI Model, the physical Layer.  You’ll learn what is met by physical layer, what is met by working at that specific layer, and what if any interrelationship or impact exists with other layers in the OSI model. Then you’ll observe diagrams and demonstrations of component process flows which explain this concept in action.
