What is the difference between Freeze and Disable?

I came upon the disable track function recently, but I am not sure what the difference between doing this and freezing a track, which is what I was doing previously. Thanks!

Forgive me, but the differences are simple (and quite obvious?):

Freezing a track renders instruments and effects to an audio file, allowing you to still work with it and free up resources. Whereas disabling a track does precisely that…it disables all functionality and the engine does not read the audio from disk
