No intention for commercial use In Sept 1991, Linus Torvalds, a second year student of Computer Science at the University of Helsinki, developed the preliminary kernel of Linux, known as Linux version 0.0.1 BEGINNING OF LINUX
- 7. Linux has been used for many computing platforms PC, Supercomputer Commercial vendors moved in Linux itself to provide freely distributed code. They make their money by compiling up various software and gathering them in a distributable format Red Hat, Slackware, etc About 29 million people use Linux worldwide LINUX TODAY
- 8. Free software, as defined by the FSF (Free Software Foundation), is a "matter of liberty, not price." To qualify as free software by FSF standards, you must be able to: Run the program for any purpose you want to, rather than be restricted in what you can use it for. Share the program with others. Improve the program and release those improvements so that others can use them. LINUX-FREE SOFTWARE

Popular for use on servers Gentoo Linux : Gentoo is a specialty distribution meant for programmers LINUX SOFTWARES
- 10. Ubuntu is a free Linux distros Ubuntu is reliable and stable. Ubuntu is the distribution with the biggest software repositories. Ubuntu has a good hardware support for most available companies. Ubuntu have a lot of variants (Kubuntu, Xubuntu, Edubuntu, Goubuntu, MIDI Ubuntu). UBUNTU

- 28. Powerful Runs on multiple hardware platforms Users like its speed and stability No requirement for latest hardware It’s “free” Licensed under GPL Vendors are distributors who package Linux WHY LINUX?
- 29. Multi-user A multi-user operating system allows for multiple users to use the same computer at the same time and/or different times. Multiprocessing An operating system capable of supporting and utilizing more than one computer processor
- 30. Multitasking An operating system that is capable of allowing multiple software processes to run at the same time Multithreading Operating systems that allow different parts of a software program to run concurrently.
- 31. People improve it, people adapt it, people fix bugs. And this can happen at a speed that, compared to conventional software development, seems astonishing Open Source Software
- 32. As there is a limited access Of user to basic files and folders, in Linux network it provide security to user’s privacy. Without disclosing the secured data Linux acts as a efficient server Linux Provide Security
- 33. Linux is Virus Free!! Linux is "virus-free" in that there are essentially no viruses for Linux in the wild, although research viruses certainly do exist.
- 34. Keeping up to date By Upgrading Linux upgrades faster than Windows Compatibility Linux is Backward Compatible unlike Windows
- 35. Linux systems are extremely stable Linux is Free No threat of viruses Linux comes with most of the required software pre- installed Update all your software with minimum fuss Linux never gets slow Linux does not need defragmentation Linux can even run on oldest hardware Adding more software is a matter of a few clicks Most Windows-only apps have their either their native version or alternatives for Linux With Linux, you get the highest degree of possible customizability ADVANTAGES OF LINUX
