Question

What layer does Protocol RPC belong to in the DOD model? and in the OSI Model? Port#? What does it stand for and what does it do?

A) DOD Model: Presentation, OSI Model: Presentation, Port#: 111, Stands for: Remote Procedure Call, Function: Communication between processes.
B) DOD Model: Application, OSI Model: Application, Port#: 101, Stands for: Rapid Protocol Connection, Function: Fast data transfer.
C) DOD Model: Application, OSI Model: Transport, Port#: 110, Stands for: Reliable Process Communication, Function: Error recovery.
D) DOD Model: Presentation, OSI Model: Session, Port#: 115, Stands for: Remote Processing Control, Function: Session initiation.

Answer 1

The Protocol RPC belongs to the Application layer in both the DOD and OSI models. It uses Port number 111 and enables communication between processes on different systems.

Step-by-step explanation:

The Protocol RPC, or Remote Procedure Call, belongs to the Application layer in both the DOD (Department of Defense) model and the OSI (Open Systems Interconnection) model.

In the DOD model, the Application layer is responsible for providing network services to the user applications. This layer interacts with the Presentation layer above it and the Transport layer below it.

In the OSI model, the Application layer is also responsible for providing network services to user applications, such as file transfer and email. It interacts with the Presentation layer above it and the Transport layer below it.

The Port number associated with Protocol RPC is 111. Port numbers are used to identify specific services or processes running on a computer. Protocol RPC enables communication between processes on different systems, allowing for remote execution of procedures or functions.
