I am a practical person but, it would save me hours from coding if I knew a bit of theory behind all these initial calls "using System;" etc. to my coding.......

e.g lets take the line "using System.Collections.Generic;"

What is System / Collections and Generic
Are they files? What is the path to their folder?

I also want to ask what Namespace is and what it is used for.

Thanks in advance

With Love.
