Thank you Mikorist.
Now another thing. This class doesn't require any software such as no info on whether or not I need to install this or not. Now I guess what I'm curious about is Linux-Unix different from Linux or what's the difference? Also, is Linux-Unix free, or where do I download it, or should I wait to see what the school is going to have me do?
I guess I'm just trying to get ahead of the game. It's not like I need it, "right now" or anything. I don't start this class till February 19th.
