Host more than one site (no replies)

Hi, I was just wondering how I host more than one site at once through wamp?

So I want to host
[www.example.com]
and
[www.example1.com]
At the same time, how do I do this?

How do I point both sites to their different directories?
I tried this before, but it kept loading my main site for the second site just different domain name

What do I need to add/change?
Thank you
