i will...

it's pretty complicated...
well. you heard right, yet wrong.

servers work like this:

-your browser sends a request over the internet
-the server sees it, and shows a page.

of course, it's not so simple, but that's enought for today.

First, you have Linux, or in your case, UNIX. Linux and Unix are not programs, but operation systems.

i reccommed linux.
since i can see that you may not be here anymore, please post to confirm that i'm not gonna write the whole thing (it's pretty long) for nothing
