Abstract :
Here I has given the Comparative Survey of
Unix, Linux and Windows 7 Operating System. First in
brief I has given their history. Then compared their Design
principles and then compared the Security provided by
Unix, Linux and Windows 7 O.S. Finally i illustrate the
comparison between Unix and Linux and then between
Unix/Linux and Windows 7. By these Comparative
Review Linux is found to be most secure O.S. and Open
Source since it is available freely. Thus becoming the
more Popular than Unix.
