Explanation

A port is an endpoint in a network connection that allows bidirectional information transfer to and from a specific process or service on a server. Ports (like port 25 for SMTP or port 80 for HTTP) enable multiple network services to run simultaneously on the same machine by directing traffic to the appropriate server process.
