In order for an application or service to receive data, a port number must be assigned to it. What is it?

Explanation:
Port numbers are bound to a socket. An application creates a socket and binds it to a port, so data arriving at that port on the host is delivered to that socket. The process uses the socket to read or write data, and a single process can own multiple sockets with different ports. So the port is associated with the socket, not with the process itself.
