    Hello

    As I understand the windows or linux os is an interface which relates the user with the shell(Dos,bash...etc) which in turn communicate with the computer HW-through other layers of lower level- to perform the operations..is that right ?

    then whats under windows is DOS ? I mean if I bought a computer with no OS I will found DOS ? and what about cmd.exe, is it DOS or some other shell ?

    I know that GNU Linux works with a bash shell right ? so if installed Linux on a computer the bash shell will replace the DOS ?

    sorry for my long topic I just want tounderstand this issue simply

    thank you

    Windows 3.1 had DOS as a base but the recent windows does not have DOS as a OS anyway and cmd.exe is just a utility tool

    Linux is more secure then Windows. Most of big organizations prefer to use Linux due to security reasons.
