        What is Linux? This question is the first question to jump into your mind when u hear the word for the first time, but when you know that it is an operating system for PCs, the second question comes to mind, is it like windows? Well read the next few lines and u might come out with an answer; (Source http://www.linuxdoc.org/HOWTO/INFO-SHEET-1.html)

        Linux is a completely free reimplementation of the POSIX specification, with SYSV and BSD extensions (which means it looks like Unix, but does not come from the same source code base), which is available in both source code and binary form. Its copyright is owned by Linus Torvalds <torvalds@...> and other contributors, and is freely redistributable under the terms of the GNU General Public License (GPL). A copy of the GPL is included with the Linux source; you can also get a copy from ftp://prep.ai.mit.edu/pub/gnu/COPYING

        Linux, per se, is only the kernel of the operating system, the part that controls hardware, manages files, separates processes, and so forth. There are several combinations of Linux with sets of utilities and applications to form a complete operating system. Each of these combinations is called a distribution of Linux. The word Linux, though it in its strictest form refers specifically to the kernel, is also widely and correctly to refer to an entire operating system built around the Linux kernel. For a list and brief discription of various distributions, see http://sunsite.unc.edu/LDP/HOWTO/Distribution-HOWTO.html None of these distributions is ``the official Linux''.

        Linux is not public domain, nor is it `shareware'. It is `free' software, commonly called freeware or Open Source Software[tm] (see http://www.opensource.org), and you may give away or sell copies, but you must include the source code or make it available in the same way as any binaries you give or sell. If you distribute any modifications, you are legally bound to distribute the source for those modifications. See the GNU General Public License for details.

        Linux is no longer considered to be in beta testing, as version 1.0 was released on March 14, 1994 . There are still bugs in the system, and new bugs will creep up and be fixed as time goes on. Because Linux follows the ``open development model'', all new versions will be released to the public, whether or not they are considered ``production quality''. However, in order to help people tell whether they are getting a stable version or not, the following scheme has been implemented: Versions n.x.y, where x is an even number, are stable versions, and only bug fixes will be applied as y is incremented. So from version 1.2.2 to 1.2.3, there were only bug fixes, and no new features. Versions n.x.y, where x is an odd number, are beta-quality releases for developers only, and may be unstable and may crash, and are having new features added to them all the time. >From time to time, as the currect development kernel stabilizes, it will be frozen as the new ``stable'' kernel, and development will continue on a new development version of the kernel. Note that most releases of the Linux kernel, beta or not, are relatively robust; ``stable'' in this context means ``slow to change'' in addition to ``robust''.

        Most versions of Linux, beta or not, are quite robust, and you can keep using those if they do what you need and you don't want to be on the bleeding edge. One site had a computer running version 0.97p1 (dating from the summer of 1992) for over 136 days without an error or crash. (It would have been longer if the backhoe operator hadn't mistaken a main power transformer for a dumpster...) Others have posted uptimes in excess of a year. One site still had a computer running Linux 0.99p15s over 600 days at last report.

        One thing to be aware of is that Linux is developed using an open and distributed model, instead of a closed and centralized model like much other software. This means that the current development version is always public (with up to a week or two of delay) so that anybody can use it. The result is that whenever a version with new functionality is released, it almost always contains bugs, but it also results in a very rapid development so that the bugs are found and corrected quickly, often in hours, as many people work to fix them.

        In contrast, the closed and centralized model means that there is only one person or team working on the project, and they only release software that they think is working well. Often this leads to long intervals between releases, long waiting for bug fixes, and slower development. The latest release of such software to the public is sometimes of higher quality, but the development speed is generally much slower.

        For a discussion of these two models, read ``The Cathedral and the Bazaar'' at http://sagan.earthspace.net/~esr/writings/cathedral-bazaar/ by Eric Raymond.

         

        If you have reached so far, then hope you have found out some information about Linux (with more to come hopefully).

        For any inquiries or question u may email me (I might take some time to reply if I' busy L)
