Question

What layer does Protocol FDDI 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: Network, OSI Model: Data Link, Port: 180, Stands for: Fiber Distributed Data Interface, Function: Data link layer for fiber optic networks
B) DOD Model: Data Link, OSI Model: Physical, Stands for: FDDI Data Link Protocol, Function: FDDI data link layer communication
C) DOD Model: Transport, OSI Model: Transport, Port: 144, Stands for: FDDI Transport Protocol, Function: Transport layer for FDDI
D) DOD Model: Presentation, OSI Model: Presentation, Port: 320, Stands for: FDDI Presentation Protocol, Function: Presentation layer for FDDI

Answer 1

Its a research prototype that includes internet layers such as exponential growth of security in e-commerce.

Answer 2

FDDI stands for Fiber Distributed Data Interface and it corresponds to the Data Link layer in both the OSI and DOD models, facilitating data link layer communication over fiber optic networks without using a port number.

Step-by-step explanation:

The Protocol FDDI stands for Fiber Distributed Data Interface, and it belongs to the Data Link layer of the OSI Model, and to the same layer in the DOD Model. The FDDI protocol does not have an associated port number as it operates at a lower level in the network stack where port numbers, which are used for distinguishing between different network services at the Transport layer, are not applicable. The primary function of FDDI is to provide Data link layer communication over fiber optic networks, allowing for high-speed data transfer and network reliability.
