IHaveAQuestion

...each other? I'm looking to learn how to like program using Unix and stuff but I'm not sure like what CSS is and like what Javascript is. I basically know what html is because that's like what webpages are based on. Also, since like Apple is based on Unix programming, what is Microsoft Windows based on.?

You may think I'm completely stupid but I'm just a beginner and am wondering what each thing is...

Thanks in advance
