WHAT IS LINUX?

+ Linux is a clone of the operating system Unix, written from scratch by
+ Linus Torvalds with assistance from a loosely-knit team of hackers across
+ the Net. It aims towards POSIX and Single UNIX Specification compliance.
- It has all the features you would expect in a modern fully-fledged
- Unix, including true multitasking, virtual memory, shared libraries,
- demand loading, shared copy-on-write executables, proper memory
- management and TCP/IP networking.
+ It has all the features you would expect in a modern fully-fledged Unix,

+ loading, shared copy-on-write executables, proper memory management,
+ and multistack networking including IPv4 and IPv6.
It is distributed under the GNU General Public License - see the
accompanying COPYING file for more details.
ON WHAT HARDWARE DOES IT RUN?
- Linux was first developed for 386/486-based PCs. These days it also
- runs on ARMs, DEC Alphas, SUN Sparcs, M68000 machines (like Atari and
- Amiga), MIPS and PowerPC, and others.
+ Although originally developed first for 32-bit x86-based PCs (386 or higher),
+ today Linux also runs on (at least) the Compaq Alpha AXP, Sun SPARC and
+ UltraSPARC, Motorola 68000, PowerPC, PowerPC64, ARM, Hitachi SuperH,
+ IBM S/390, MIPS, HP PA-RISC, Intel IA-64, DEC VAX, AMD x86-64, AXIS CRIS,
+ and Renesas M32R architectures.
+ Linux is easily portable to most general-purpose 32- or 64-bit architectures
+ as long as they have a paged memory management unit (PMMU) and a port of the
+ GNU C compiler (gcc) (part of The GNU Compiler Collection, GCC). Linux has
+ also been ported to a number of architectures without a PMMU, although
+ functionality is then obviously somewhat limited.
