Question

which three protocols or standards are used at the application layer of the tcp/ip model? (choose three.)
mpeg
http
tcp
gif
udp
ip

Explanation:

• HTTP (Hyper - Text Transfer Protocol): It is an application - layer protocol used for transferring hypertext (web pages, etc.) between clients (e.g., web browsers) and servers.
• MPEG (Moving Picture Experts Group): MPEG standards are used for encoding and decoding audio and video. In the context of the TCP/IP model, when dealing with multimedia content transfer over the network (which is an application - layer concern like streaming media), MPEG - related protocols (e.g., for streaming) are relevant at the application layer.
• GIF (Graphics Interchange Format): Although GIF is mainly a graphics file format, when it comes to transferring GIF - formatted images over the network (e.g., in web applications), it is part of the application - layer data transfer.

• TCP (Transmission Control Protocol): It is a transport - layer protocol. It is responsible for providing reliable, ordered, and error - checked delivery of a stream of bytes between applications running on hosts communicating via an IP network.
• UDP (User Datagram Protocol): It is also a transport - layer protocol. It provides a simple, connectionless, unreliable datagram service.
• IP (Internet Protocol): It is a network - layer protocol. It is responsible for routing packets across network boundaries.

Answer:

MPEG, HTTP, GIF
