What is the difference between port 1433 and 1434?

The default instance of SQL Server listens on Port 1433. Port 1434 is used by the SQL Browser Service which allows connections to named instances of SQL Server that use dynamic ports with out having to know what port each named instance is using, especially since this can change between restarts of the named instance.
