Oracle 11gR2 Dedicated Server with Dispatcher

I've just run the installer to install the Oracle 11gR2 database software and create a database.  (I'm also using ASM.)  During the database creation process, I chose to use a Dedicated server versus a Shared server.  Now that everything is up and running, the database is running in dedicated server mode.  I've verified this by running this query:  SELECT sid, username, server FROM v$session WHERE type='USER';

However, by doing SELECT * FROM v$dispatcher, I've discovered that a dispatcher is running.  I thought the dispatcher was only used in a shared server environment.  Am I missing something?

Thanks,
Emily
