    HTTP

    Explanation
    HTTP is a protocol used for transferring data over the internet. It operates on port number 80, which is the default port for HTTP communication. When a client sends an HTTP request to a server, it uses port 80 to establish a connection and transfer the requested data. Port 80 is specifically reserved for HTTP traffic, allowing servers to listen for incoming HTTP requests and respond accordingly. Therefore, the correct answer is 80.

    PortMapper is a software application that maps network ports on a computer to different services or applications. It allows incoming network traffic to be directed to the appropriate application or service running on the computer. In this case, the correct answer is 111, which is likely referring to the well-known port number for the Remote Procedure Call (RPC) protocol. This port is commonly used for communication between networked devices and allows them to execute procedures on remote systems.
