Question

What layer does Protocol FTP 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 Layer, OSI Model: Application Layer, Port#: 20/21, Stands for: File Transfer Protocol, Function: File transfer between hosts.
B) DOD Model: Transport Layer, OSI Model: Session Layer, Port#: 23, Stands for: File Transmission Protocol, Function: Terminal emulation.
C) DOD Model: Application Layer, OSI Model: Presentation Layer, Port#: 69, Stands for: Fast Transfer Protocol, Function: Rapid data transmission.
D) DOD Model: Data Link Layer, OSI Model: Data Link Layer, Port#: 80, Stands for: File Transport Protocol, Function: Web server communication.

Answer 1

FTP is categorized in the Application layer of both the DOD model and the OSI Model, it uses Port 20 for data transfers and Port 21 for control, and stands for File Transfer Protocol which is used for transferring files between hosts.

Step-by-step explanation:

The File Transfer Protocol (FTP) belongs to different layers in the DOD model and the OSI Model. In the DOD model, which is also known as the TCP/IP model, FTP is categorized in the Application layer. In contrast, in the OSI Model, FTP belongs to the Application layer as well. FTP utilizes two ports: Port 20 for data transfer and Port 21 for control (commands and responses).

FTP stands for File Transfer Protocol, which is a standard network protocol used to transfer files from one host to another over a TCP-based network, such as the Internet. It provides a way for users to upload or download files to/from their servers and is widely used for transferring large files securely.
