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.

Linux was first developed for 32-bit x86-based PCs (386 or higher).
These days it 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 and CRIS
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).
