What is Linux? (Copied from
Linux is a freely-distributable, independent Unix-like operating system for x86, Motorola 68k, Digital Alpha and Motorola
PowerPC machines. It is an implementation of the POSIX specification with which all true versions of Unix comply. The Linux
kernel uses no code from AT&T or any other proprietary source, and much of the software available for Linux is developed by
the Free Software Foundation's GNU project.
It supports a wide range of software, including X Windows, Emacs, TCP/IP networking (including SLIP/PPP/ISDN), the
works. Many people have executed benchmarks on 80486 Linux systems and found them comparable with mid-range
workstations from Sun and Digital.
