Question

What layer does Protocol TCP belong to in the DOD model? and in the OSI Model? What does it stand for and what does it do?

A) DOD Model: Transport, OSI Model: Transport, Stands for: Transmission Control Protocol, Function: Reliable data transmission
B) DOD Model: Application, OSI Model: Presentation, Stands for: Total Control Protocol, Function: Comprehensive control over data
C) DOD Model: Network, OSI Model: Network, Stands for: Transfer Control Protocol, Function: Network data transfer control
D) DOD Model: Session, OSI Model: Session, Stands for: Tactical Control Protocol, Function: Session management for military communications

Answer 1

TCP belongs to the Transport layer in both the DoD and OSI models, is known as Transmission Control Protocol, and ensures reliable data transmission.

Step-by-step explanation:

The Protocol TCP belongs to the Transport layer in both the DoD (Department of Defense) Model and the OSI (Open Systems Interconnection) Model. TCP stands for Transmission Control Protocol. Its primary function is to provide reliable data transmission between devices in a network. TCP achieves this by establishing a connection between the sender and the receiver and ensuring that packets of data are transmitted securely and in the correct order. If packets are lost or arrive out of sequence, TCP will request a retransmission to ensure complete and accurate delivery of information. This is essential for applications where data integrity and correctness are crucial, such as in web browsing, email, and file transfers.
