  1. Key “A”
    Question no.16 option “A” is the correct answer because Option “B”, or “C” is nit operating system. Look a carryfully in question paper Option (b)window 2000, not Windows 2000, and Option (C) Linus is not opearating sustem , but Linux is o/s.

    • Thanks for your suggestion.
      But I think that is just typing mistake and as far as I know Linux is not an operating system itself, it is just an OS Kernel, based on which OS are developed. Red Hat, Ubuntu, Fedora, Android are the Linux based OS which uses Linux Kernel.
