What type of communication occurs between the layers of the OSI model?
Understand the Problem
The question is asking about the type of communication that takes place between the layers of the OSI model. The OSI model is a framework used to understand and implement networking protocols in layers, and this inquiry focuses on how these layers interact with each other.
Answer
Communication occurs through service primitives and defined interfaces between layers.
Communication between different OSI model layers is typically through service primitives, which are interfaces or abstractions provided by one layer for the layer above to utilize. Thus, communication between layers is not direct but through these defined interfaces.
Answer for screen readers

More Information
The OSI model uses a conceptual framework where each layer serves the layer above it and is served by the layer below. Communication is facilitated through service access points (SAPs) and service data units (SDUs) at each interface, providing uniform communication rules.
Tips
A common mistake is thinking that layers directly communicate peer-to-peer instead of using established interfaces or abstractions.
