What is an example of an Application Layer protocol?

The correct answer is HTTP, which stands for Hypertext Transfer Protocol. HTTP is designed to facilitate the transfer of hypertext content on the World Wide Web, allowing users to view and interact with web pages. It operates at the Application Layer of the Internet Protocol Suite, meaning it is concerned with the protocols for specific data handling and user-facing applications.

In contrast, TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are transport layer protocols focused on how data packets are transmitted across the network. They handle error checking, session management, and other aspects related to data transfer, not the content itself. IP (Internet Protocol) is a network layer protocol that is primarily responsible for addressing and routing packets of data between devices on a network. Thus, HTTP stands out as a specific application layer protocol, enabling web browsers and servers to communicate effectively.
