Porta

Nei protocolli TCP/IP e UDP/IP un numero che identifica la connessione logica che utilizza un software (es. il mail server) con un client o server in una rete.
Le porte disponibili per la connessione vanno dal numero 0 al numero 65536. Le porte dal numero 0 al numero 1024 sono riservate secondo le specifiche emesse dalla IANA e descritte nella RFC 1700.
