Question

What layer does Protocol APPLE TALK 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: Network, Port#: 1640, Stands for: Apple Transmission Layer, Function: Network communication.
B) DOD Model: Data Link, OSI Model: Data Link, Port#: 120, Stands for: Apple Link, Function: Data link management.
C) DOD Model: Network, OSI Model: Network, Port#: 102, Stands for: Apple Data Talk, Function: Data exchange.
D) DOD Model: Presentation, OSI Model: Presentation, Port#: N/A, Stands for: Apple Presentation Protocol, Function: Presentation layer services.

Answer 1

No given option correctly describes the placement of AppleTalk in the DoD or OSI models, nor does it provide a correct port number or description of AppleTalk's function, as it operates across several layers and does not use TCP/IP ports.

Step-by-step explanation:

The protocol AppleTalk belongs to different layers in the Department of Defense (DoD) model and the Open Systems Interconnection (OSI) model. AppleTalk is a suite of protocols developed by Apple Inc. for networking and it covers several layers of networking communication.

However, none of the options (A, B, C, D) accurately describe the placement of AppleTalk within the DoD or OSI models, nor do they provide a correct port number or description of AppleTalk's function. AppleTalk actually operates at several layers. Its primary protocols, AppleTalk Address Resolution Protocol (AARP), Datagram Delivery Protocol (DDP), and AppleTalk Session Protocol (ASP), would correspond to the Network Layer in both the OSI and DoD models, while AppleTalk Filing Protocol (AFP) would function somewhat at the Presentation Layer but it is not a direct match since OSI and DoD models do not have altogether corresponding layers nor direct equivalents for AppleTalk's various protocols. AppleTalk does not have a specific port number as it is not a TCP/IP protocol and does not operate over ports like TCP/IP protocols do.
