Introduction KV Central Railway Solapur, [email protected] ubuntu THE NEW OPERATING SYSTEM TO REPLACE WINDOWS Bio-data WHY USE LINUX? What is Linux ? Open Source-Where Everyone Can Be a Developer? What is Linux Distribution? Difference between Ubuntu and Linux Why choose Ubuntu? Why Use Linux? Powerful, modern design Freely available source code means no lock-in to a single vendor Thousands of free, powerful applications Support for standards Lower total cost of ownership i.e no licensing fees Stable, powerful and virus-free What is Linux ? From servers to ipods, hardcore programmers to enthusiasts, all inclusive 6GM installation to floppy bootable, Linux is everywhere. Linux is standing today showing the IT world the innovation that can be achieved by sheer community work. And, Linux is free too. It appears, there is after all something like a free lunch! When the world around you is trying Linux, why would you want to be leaving behind the excitement? What Is Linux? In popular usage, “Linux is an operating system.” ,however, the strictest definition of Linux is only the kernel. The more relaxed definition would be an overall package called a distribution that is ready to install and use. There are well over 300 distributions of Linux, most of them containing commonly-needed applications—and even games! Linux was originally meant to be a UNIX clone. Here, by “clone,” we mean that it would look and behave like UNIX. But bear in mind that Linux does not contain a single line of UNIX code! The source code of the two is entirely different. Open Source-Where Everyone Can Be a Developer? A source code is the program code exactly as it is written by the programmer: the raw code that is not compiled and is editable is the source code. (Compilation is the process of finalising a code for execution.) For an operating system, the source code runs into several Thousands of lines that appears “as written.”(Needless to say, deciphering the l ogic behind the source code an be quite a task even for a competitive programmer.) Since the source code is in raw, un-compiled format, anyone who has access to it can make his own additions, deletions or changes—and hence his own versions of the software with modified or added features. What is a Linux Distribution? This is where the beauty of open source lies. Computer magazines and Linuxrelated web sites discuss Red Hat Linux, SUSE Linux, the Novell Linux Desktop, Fedora Core Linux, and many other things ending in Linux, each available from a different company or organization. We found over 350 different distributions of Linux on www.linux.org! Wecan’t say all of them are bug-free, but work is ongoing, and support is available for all major distributions. Ubuntu Vs Linux Linux is a generic term referring to Unix-like operating systems, and it has various types of distributions; Ubuntu is just one of them. Actually, Linux was officially introduced only in 1991 by its famed creator Linus Torvalds, who at the time was a student at the University of Helsinki in Finland. Little did he know that his creation would grow in size and popularity to the extent it has today. The reason for the increasing awareness of Linux operating systems for personal computing use, is mainly due to the Ubuntu distribution founded in the year 2004. What is Ubuntu? Ubuntu is based on Linux, a project initiated by the South African, multimillionaire named Mark or Shuttleworth. It is in fact just one of the Linux distributions, ‘distros, along with Fedora, Suse, Mandriva and Debian. To date, it is perhaps the most popular one, as it was claimed to be most used type of Linux based OS in desktop installations. Ubuntu is an ancient African word, meaning”humanity to others”.Ubuntu also means “what I am because of who we all are”. Ubuntu provides a user friendly and stable OS which is targeted towards the average computer user. It boasts simplicity, and ease of installation as well. Why Choose Ubuntu? Regular, up-to-date releases Commitment to quality Community and commercial support Easy retrieval and application of updates Focus on usability Focus on internationalization Active and involved community Installing Ubuntu Family Tree Is there any Question?
