1. It depends on the language that the application is written in. For example, I have written Java web applications that are deployed and run on Linux servers, but my development, testing, and build environment was MS-Windows.

   It is also not too hard to write C/C++ programs that will run on any UNIX-like system, including Linux. But the actual build does have to be done on the intended operating system unless you have a so-called "cross-compiler". Such a compiler allows you to name a target system for which you are building the application.

2. Well if you use Java for programming u just write once and run anywhere
3. Many, many years of programming experience on UNIX and Linux systems.
4. NO THAT'S NOT TRUE THE CORRECT HE LINUX BUILT ON ANY OPERATING SYSTEM
