    Which one of the following is not an application layer

    protocol used in internet?
    A HTTP Correct Answer Incorrect Answer
    B FTP Correct Answer Incorrect Answer
    C TCP Correct Answer Incorrect Answer
    D SMTP Correct Answer Incorrect Answer

    Solution

    HTTP (Hypertext Transfer Protocol), FTP (File Transfer Protocol), and SMTP (Simple Mail Transfer Protocol) are all application layer protocols used to manage and transfer data across the internet. TCP (Transmission Control Protocol), on the other hand, operates at the transport layer, not the application layer. It is responsible for ensuring reliable data transmission between devices.
