Correct:
D
Explanation
In computer networking models (OSI and TCP/IP), protocols are organized into layers. The Application Layer is the layer that interacts directly with software applications like web browsers or email clients.
- SMTP (Simple Mail Transfer Protocol): Used for electronic mail transmission (Application Layer).
- FTP (File Transfer Protocol): Used for the transfer of computer files between a client and server (Application Layer).
- HTTP (Hypertext Transfer Protocol): The foundation of data communication for the World Wide Web (Application Layer).
- TCP (Transmission Control Protocol): This is a Transport Layer protocol. It provides reliable, ordered, and error-checked delivery of data between applications running on hosts communicating over an IP network.
Since TCP operates at the Transport Layer, it is not an application layer protocol.
