OEM is something that, they provide you the CD-Key and Installation CD ONLY.

Example : Microsoft Windows Vista Ultimate (OEM) and Microsoft Windows Vista Ultimate (Retail Pack).

I believe you saw a lot of pc shops selling OEM Windows Software (which only CD + CD Key + a white plastic box) .. Compare to Retail Pack, Retail Pack is much more beautiful box. Below is the pic :
