Question

What layer does Protocol MPEG 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: 323, Stands for: Moving Picture Experts Group, Function: Audio and video compression at the presentation layer
B) DOD Model: Network, OSI Model: Network, Port: 500, Stands for: MPEG Network Protocol, Function: Networked MPEG communication
C) DOD Model: Transport, OSI Model: Transport, Stands for: Moving Picture Transport Protocol, Function: Transport layer for MPEG
D) DOD Model: Application, OSI Model: Application, Port: 420, Stands for: MPEG Application Protocol, Function: Application layer for MPEG

Answer 1

MPEG stands for Moving Picture Experts Group and operates at the Presentation layer in both DoD and OSI models, focusing on audio and video compression without a designated port number.

Step-by-step explanation:

The Protocol MPEG belongs to the Presentation layer in both the Department of Defense (DoD) model and the Open Systems Interconnection (OSI) Model. MPEG does not have a specific port number because it is not a network protocol that uses ports for communication; rather, it is a standard for compressing audio and video data. MPEG stands for Moving Picture Experts Group, which is the name of the working group that develops standards for audio and video compression and transmission. Its function is primarily related to the standardization of audio and video formats to facilitate efficient, synchronized delivery and playback across various devices and platforms, which takes place at the presentation layer.
