Linux is a complete, free distributable (under the GNU license) clone of UNIX operating system for 386/486/pentium procesors. Ports to other architectures, such as Alpha, Sun, Macintosh, Amiga, etc are being done as well. You can get Linux for free via FTP from many sites in the Internet.

Although sunsite.unc.edu and tsx-11.mit.edu are the main FTP archive sites which carry the Linux software and documentation, many diferent sites around the world mirror these two ones. Thus, when downloading your copy of Linux, you should choose the geographically nearest site to you in order to reduce network traffic.

If you are interested on knowing more about Linux, you shuold visit the Linux: The Operating System for the new Millenia Page and the Linux Documentation Project Page, where you will find a set of free manuals a group of volunteers around the world is writing for this great operating system.
