Question

How does information get passed from one osi layer to the next?

Answer 1

OSI layer is Open Systems Interconnection (OSI) . OSI  divides the duties of the Application layer into three layers: Application, Presentation, and Session. OSI splits the activities of the Network Access layer into a Data Link layer and a Physical layer. This increased subdivision adds some complexity, but it also adds flexibility for developers by targeting the protocol layers to more specific services. In particular, the division at the lower level into the Data Link and Physical layers separates the functions related to organizing communication from the functions related to accessing the communication medium. The three upper OSI layers offer a greater variety of alternatives for an application to interface with the protocol stack

Answer 2
