FEATURES

WINDOWS 2000:

GUI based desktop OS-Microsoft bannered.

  • both single user multitasking and multi-user multitasking

  • Supports SMPs,threads,IPCs etc.,

  • concurrency mechanisms-mutex, semaphores etc.,

  • Scheduling-priority driven preemptive round robin within a priority level

    LINUX:

    Linus Torvalds announced his work first on Aug. 5 1991.

  • considered a full featured Unix system running on a variety of platforms.

  • Scheduling- traditional Unix scheduling with two new classes.


General comparison


PERFORMANCEgiven below are some of the performance criterion comparisons


PERFORMANCE continues

Performance

-depends on the appln.

-each OS has its own merits its own merits which depend on the appln.


SECURITY

  • Windows 2000:

    • developed as a desktop OS

    • security pervades the entire system.

    • vulnerable to e-mail attacks.

  • Linux:

    • Good networking OS

    • ‘Root’ alone has the access right to touch the system programs.hence system suffers no difficulty.

    • separate user account creation specifically for running email attachments can isolate the account and so, no virus or a trojan can attack.


SECURITY

  • Standard installation wise-

  • -Windows 2000 looks better.

    • Kerberos protocol for simple user authentication and access control in the network.

    • EFS(Encrypted File System)- contained in NTFS 5.0 Windows 2000 file system as a standard solution.

  • -Linux needs additional installation efforts for all these.

  • Windows 2000 provides simple PKI(public key interface).

  • but even with all these things…

  • Windows looks inferior to Linux in security.

  • No Linux system has sofar reported any crash.


  • CONCLUSION

    • -Comparisons dealt, though didn’t give the total picture,may give a vision of the features.

    • -its always the application and the user- the two deciding factors of choosing a OS.

    • Many companies use a combination.

    • So, Better to have an application specific usage
