New to Linux?
Linux is a kernel....
It is not the operating system, it's one of the essential major components of the system. The system as a whole is more or less the GNU system, with Linux added.
Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run, it can only function with a complete operating system.
The available free software added up to a complete system, because of the GNU Project which had started since 1984, many people have made major contributions to the free software.

Simplified history of Unix-like operating systems.
Linux shares similar architecture and concepts (as part of the POSIX standard) but does not share non-free source code with the original Unix or MINIX.
Getting the very best return on your IT investment with GNU/Linux.
Getting the very best return on your IT investment is not always straightforward, and that's where the Linux Community can be of help.
Did you know: Linux source code for all supported architectures is contained in about 4500 C and Assembly files stored in about 270 subdirectories; it consists of about 2 million lines of code, which occupy more than 58 megabytes of disk space.
Linux is a tiny operating system when compared with other commercial giants. Micro$oft Windows 2000, for example, reportedly has more than 30 million lines of code. Linux is also small when compared to some popular applications; Netscape Communicator 5 browser, for example, has about 17 million lines of code.
One of the more appealing benefits to Linux is that it isn't a commercial operating system: its source code under the GNU Public License is open and available to anyone to study, the official site is http://www.kernel.org/ The GNU project is coordinated by the Free Software Foundation, Inc. (http://www.gnu.org/); its aim is to implement a whole operating system freely usable by everyone. The availability of a GNU C compiler has been essential for the success of the Linux project.
The fundamental architecture of the GNU/Linux operating system, GNU/Linux provides robust & scalable platform for changing business.
In some ways, Linux is the champion of a set of ideals. Whether you buy into these ideals is a separate issue from whether you use the technology, of course, but nonetheless a complete understanding of Linux and Linux-based systems requires at least an awareness of the legacy.
GNU+Linux is an operating system, but it's also representative of a lot more.
Linux-based operating systems are extremely powerful and flexible, but unlocking that power and flexibility requires knowledge and understanding of how the system works. Note:Linux is "merely" a kernel. That is, Linux is a piece of software that manages resources and processes, but provides no system libraries or user interface.
Since Linux is just a kernel, it requires a set of system libraries to become a useful environment. If Linux is just a kernel, where do these system libraries come from? Who writes them? Who maintains them? Obviously, whoever maintains these libraries makes a huge contribution to Linux systems in general. In the vast majority of Linux installations, the system libraries are the GNU utilities, written and maintained by the Free Software Foundation.
