If you really have no idea what it is, Google is, as usual, the place to go. It is apparently the name and course number of a New York University School of Continuing and Professional Studies class:
The course description on the site makes it sound like a very rudamentary introduction to the MacOS and the basics of computer color--CMYK vs RGB, that sort of thing.
I actually did google it and got the same thing. I didn't realize that it was the course #. I thought it was a specific color system that i wasn't aware of.
