Windows, Macintosh, and Linux r the 3 most popular OS. All they provide a way for computers to store, launch, and organize programs and files and web related tasks. Mac regulates the design of SW/HW add-ons more rigidly than MS, so SW/HW added to a Mac is less likely to fail. While Linux is also popular OS in the market. It is based on Unix, an OS used for more than 3 decades that now powers about 90% of Web sites. In sharp contrast to both Wind and Mac, Linux is an open source project. As such, anyone can modify Linux code, and though it is free to use and distribute. Although Linux offers greater security and flexibility than other OS and requires some technical knowledge to install and use. For desktop/home purpose, Linux is very cheap or almost free, while Wind is expensive. For server use, Linux is very cheap compared to Windows..... Windows allows programs to store user information (files and settings) anywhere. This makes sometimes impossibly hard for the users to backup user data files and settings and to switch to a new computer. where Linux stores all user data in the home directory making it much easier to migrate from an old computer to a new one. If home directories are segregated in their own partition, it is possible to upgrade from one version of Linux to another without having to migrate user data and setting. Linux has a reputation for fewer bugs than Windows. Linux is very secure, efficient & flexible than Windows and Macintosh.

Hope this helps

1) Source code will be available . Tomorrow if you wish you can edit and make you own package or Operating system. all linux os comes different company (LIndows , Lycoris, Red Hat, SuSe, Mandrake, Knopping, Slackware).all windows version comes from Microsoft :-)

2) Have more options to secure the system. If you are good admin you can perfectly make it secure.

3) Linux architecture make it more secure. Where windows all in managed by registry. as i said above point security is based on admin who manage OS.

why windows get affected always ? simple 90% of desktop users use windows. So there people to exploit this. they will install all applications :-) and open himself into security risk.

4) save money . for windows u need to pay for OS then for support (support cost u high)

5)stable. windows need many reboot as part of each application or updates. Many of my linux servers still up running for 2 yrs :-). As far there is no hardware problem linux run's perfect.

6)migration simple - since all considered as files - just copy and paste make things work.
