The Roots of Linux
The Roots of Linux
Linux’s lineage goes back to UNIX, the most proven operating system in the
world in that it (and its variants) has been the most used networked computer
OS for over three decades. UNIX was developed at Bell Telephone Laboratories
and designed to support many users working at many computers at one time, all
linked together and sharing information and resources. When using such an
operating system, more than one person can use a single computer’s hardware
to do many things at once, and a single user can do more than one thing (multi-
task) on a single machine as well. This makes for more efficient use of resources
and a more powerful system.

Linux runs on a variety of platforms, including x86, PowerPC, DEC Alpha,
Sun Sparc, and ARM, so no matter what type of computer hardware you have,
Linux will probably run on it. Linux aims for POSIX (Portable Operating
System Interface for UNIX) compliancy. POSIX is a set of standards that defines
an interface between programs and operating systems. By sticking to these stan-
dards, software developers can be reasonably confident that their programs can
be ported easily to any POSIX- compliant operating systems, such as the various
versions of UNIX. This means that Linux users can take advantage of software
made for general UNIX systems.
