In networking, a port is a numerical identifier (0-65535) that allows specific server processes or applications to send and receive data through network connections. When a client connects to a server, it specifies both the IP address and the port number to identify which service or process it wants to communicate with (e.g., port 80 for HTTP, port 25 for SMTP). This enables multiple network services to run concurrently on the same server.
