1) An AAC is a high quality file of music that is still condensed but not quite as small as an MP3 file but is more advanced. An MP3 file is a very condensed file of music that varies greatly in quality from very good quality to poor. The AIFF file is a very large music file that can be compressed but is still larger than an MP3 by far and also bigger than the AAC file. Supposedly the quality is better because of its size.

2) AAC size: 12.1 MB
   MP3 high quality size: 8.5 MB
   MP3 good quality size: 5.7 MB
   AIFF size: 62.3 MB

3) There is a difference between each of the files (though one so small on itunes that i didn't hear any difference at all). I expected the MP3 good quality to be a bit tinny but didn't honestly know it was less quality than the high quality.

4) I would choose the MP3 high quality to download onto my computer for all my files since most times MP3 fits better and i would have more room on my computer as well as my music device.
