Linux Is An Alternative Operating System
"Linux" is an alternative, "open source" operating system. It is
"alternative" because it runs on the same hardware that the
market share leader (Microsoft Windows) runs on, "open source"
because it is not only freely obtained (via various channels
such as online downloads, free CDs that come with magazines and
books, etc...), but also because it's source code (the actual
computer instructions that make the software work) is also
freely accessible and modifiable.
The fact that Linux is freely available for anyone to obtain and
tinker with has been a boon for the adoption and use of Linux
with computer enthusiasts, geeks, nerds and the like. These
enthusiasts like the fact that the code is right there in front
of them for them to change to their needs. A competent
programmer, even a hobbyist, can customize Linux to their needs
to a much more refined level than they could with MS Windows,
Apple's Mac OS, and even other more proprietary flavors of UNIX.
There is a very active and thriving developer community
surrounding Linux. There are literally thousands of websites out
there devoted to the subject matter. All sorts of knowledge
bases, forums, chat rooms and message boards are dedicated to
the goings on in the Linux and open source community.
Another excellent facet of the Linux community is the fact that
the majority of the software applications written for the
operating system is also made available with the same "open
source" license, which means that an enthusiast (or a
professional for that matter) can build and customize a Linux
system that is perfectly tailored to their needs with little to
no investment beyond the initial purchase of the hardware.
A sound studio engineer, for example, could build a Linux
machine that has been custom tailored to run the effects on a
sound board or to function as a recording device for digital
audio, while a graphic artist may build a machine that has been
built from the ground up to be an efficient design machine.
