From Wikipedia      Applications implementing common   services often use specifically   reserved  well-known port numbers for   receiving service requests from client   hosts  This process is known as   listening and involves the receipt of   a request on the well-known port and   reestablishing one-to-one   server-client communications on   another private port  so that other   clients may also contact the   well-known service port  The   well-known ports are defined by   convention overseen by the Internet   Assigned Numbers Authority  IANA     Source  So as others mentioned  it s a convention
