They are 2 different formats for sound - the compression rate and coding is different, the sizes and even players may be different. AAC is a subsection of MPEG2 and MPEG4, WAV is an older format that uses RIFFSTREAM format, is the main format used on Windows; the usual bitstream format is PCM - Pulse Code Modulation and is limited to less than 4 gigabyte sized files.
AAC/M4A are the same thing with different extensions....
WAV is a file format. There is no difference between a WAV file on Ubuntu and a WAV file on Windows.
MP3, WAV, AAC, Apple Lossless, MPEG4, AIFF
CD players will read WAV or MP3. MP3 has better audio, but smaller. WAV is a larger file, and has the same audio level.

Short answer: For most people, it's virtually impossible to hear the difference between a 256 kbps AAC audio file (which is currently the format available from iTunes) and a CD. If you're using very high quality sound equiptment, you may be able to hear a difference depending on how trained your ears are. Even then, it won't be very noticable. Still, AAC is a "lossy" format, so audio data is lost when you rip from a CD to AAC, even if your ears can't tell the difference. If you convert your AAC files to MP3 or any other "lossy" format, you will loose more sound quality with each conversion. That's partly why some audiophiles prefer to rip CDs to a lossless format such as FLAC and .wav files. These files take up much more space, but you won't loose any audio data.
