Question

What layer does Protocol Token Ring 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: 160, Stands for: Token Ring, Function: Local area network data link layer using token passing
B) DOD Model: Data Link, OSI Model: Physical, Stands for: Token Data Link Protocol, Function: Token-based data link layer communication
C) DOD Model: Transport, OSI Model: Transport, Port: 122, Stands for: Token Ring Transport Protocol, Function: Transport layer for Token Ring
D) DOD Model: Presentation, OSI Model: Presentation, Port: 420, Stands for: Token Presentation Protocol, Function: Presentation layer for Token Ring

Answer 1

Token Ring belongs to the Data Link layer in both the DoD Model and the OSI Model, and it functions by controlling data transmission through token passing.

Step-by-step explanation:

The Protocol Token Ring belongs to the Data Link layer in both the Department of Defense (DoD) Model and the Open Systems Interconnection (OSI) Model. There isn't an associated port number for Token Ring as it operates at the data link layer (Layer 2 of OSI), which is below the transport layer where port numbers are defined.

Token Ring is a networking technology that was widely used in the past. It involves the passing of a token around a ring topology network to control the right to transmit. This means that only the device holding the token has the right to transmit data at any given time. This system was designed to prevent the collision of data packets on the network.
