The lower layer protocols, such as the MAC and the physical layer, do not have to build specific interfaces to the higher layer protocols, such as layer 3, in order to communicate.

Question

Quizplus · Accepted Answer

Lower layer protocols like MAC (Medium Access Control) and the physical layer are designed to provide services to the higher layers (like layer 3, the network layer) through a standardized interface, without needing to build specific interfaces for each higher layer protocol. This abstraction allows for interoperability and modularity in the network architecture.
