differences between myisam and innodb tables ???

I want to use constraints, so I will have to use innodb tables (according to
the website mysql.com).
But, what is the difference between myisam and innodb tables ??
And why is there a comment "innodb free: 4096 kb" since I have changed my
tables from myisam to innodb?
Is this working like Sybase, where you need to create devices for data
storage, or do I miss the idea completely here?

Please notice, I am a beginner, so please be patient.

gr.,
Stefan.
