  1. CS 550 Comparitive Operating Systems Comparison of Windows 2000 and Linux on Performance and Security Presented by Makesh Balasubramanian Student ID:999-29-3290 Email:balamak@iit.edu

  2. 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.

  3. General comparison

  4. PERFORMANCEgiven below are some of the performance criterion comparisons

  5. PERFORMANCE continues Performance -depends on the appln. -each OS has its own merits its own merits which depend on the appln.

  6. 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.

  7. 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.

  8. 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
