4. How Do I Download Linux?
First, some advice: Don't download Linux to install it. Buy a copy.

Linux CDs
For less than $50, you can get a good book like Linux Unleashed or Linux: The Complete Reference that will include a CD-ROM full of Linux. These CD versions are far easier to install than the download, plus you get the added benefit of having handy written documentation around. If you're new to Linux, you'll need the docs.

Downloading the Kernel
If you insist on downloading Linux, you have a lot of options. If you're really looking to flex your tech muscles, you can simply download the kernel and build your own OS from the ground up. Unless you have a lot of time on your hands, don't. Instead, get a complete distribution. A distribution is a package that includes the Linux kernel and a variety of utilities and other software--useful things such as desktop managers, Web browsers, and the like.

Linux Distributions
You can go directly to the distribution makers--Red Hat, Caldera, Debian, or Slackware--or visit a site like Linux Online for a list of more than a dozen distributions you can download. Each distribution has its fans and particular features. Red Hat is by far the most popular, in part because of its relatively easy installation interface. Debian has a reputation for throwing in everything and the kitchen sink with its distribution. Caldera Open Linux comes complete with NetWare support. 

Once you decide which distribution you want to use, you'll need to check out the distributor's installation instructions, as they vary a bit from vendor to vendor.
