Linux is a form of Unix, one that is available free, as in it costs nothing, you are free to copy it and use it on as many computers as you like, and you can, if you are so inclined, make changes to the operating system as the full source code for the kernel is available to you.
There are many forms of Unix, such as Sun's Solaris, HP's HP-UX, Digital UNIX, any of the *BSD systems, and Linux. Linux is just another form of Unix-like system. There are other freely available Unix systems, like the BSD systems (OpenBSD, NetBSD, FreeBSD), while other ones you usually have to pay for, and likely won't get complete access to the source. (Some are in-between, like Solaris, which you can download for free under certain circumstances, and you can get the source code, but you can't really distribute changes to the OS.) As for the most common Unix, these days it feels like Linux, 'cause it's all the rage, but the most common on the big-ass servers are the proprietary Unices, like Solaris. Apache isn't a Unix system at all, it's just a web server, like Microsoft's IIS. Apache can be used on pretty much any Unix system, and can even be used on Windows platforms. (Although it's generally more stable and faster on Unix systems.) If you're really new to Unix systems (and it sounds like you are) pick up a Linux distribution like Mandrake, RedHat, or SuSE, as they're generally the easiest to install. Once you get used to Unix-like systems, you can generally move between them fairly easily, although there is a learning curve. (For instance, while Solaris and Linux are both Unices, there are quite a few differences, but if you can get used to one, it makes learning the other relatively easy, versus only knowing Windows or whatever.) IMHO, of course.
