What makes Linux different from traditional Unix



  • GNU Public License (GPL) for the Kernel and OS applications: free to use; get the source; develop and disclose your source.

  • The same Kernel and GNU C libraries (glibc) for different distributions:
    if you can run an application on one kind of Linux, its a matter of setting libraries to run it on the other distribution.

  • Runs on various computer architectures: x86, ARM, POWERPC, SPARC, ALPHA, MIPS, HPPA, etc.

  • The fastest developing OS.

  • Various vendor support.

  • Strong community support.

    Why would you run Linux?



  • Available free kernel, modifieble for specific tasks. Vendors can easily port their software into Linux, for example, file systems.

  • Various developers can work on the same software without intellectual property issues. Open source software allows upgrading and changing software by the people using it.

  • No license fee for every version of the software on any computer - no charge for scalability.

  • It is your choice what commercial software you need to buy.
