MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Layer 4 of the OSI Model Handles Transport Protocols Like TCP and UDP. Layer 4 of the OSI model, also known as the transport layer, manages network traffic between hosts and end systems to ensure complete data transfers.

Detailed explanation-2: -In terms of the OSI model, TCP is a transport-layer protocol. It provides a reliable virtual-circuit connection between applications; that is, a connection is established before data transmission begins.

Detailed explanation-3: -TCP stands for Transmission Control Protocol. It is a transport layer protocol that facilitates the transmission of packets from source to destination. It is a connection-oriented protocol that means it establishes the connection prior to the communication that occurs between the computing devices in a network.

Detailed explanation-4: -As mentioned earlier, TCP is the most common transport layer protocol. It is used by many application layer protocols like the HyperText Transfer Protocol (HTTP) and FTP. TCP was designed to provide reliable service on top of the unreliable network layer provided by IP.

Detailed explanation-5: -The Internet Layer of the TCP/IP model aligns with the Layer 3 (Network) layer of the OSI model. This is where IP addresses and routing live.
