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 CriterionWindows 2000Linux Ease of useGoodOkay User assistanceApplication specific Command specific HistoryNoGood Technical supportGoodOSS PricingHighmid and low range

4. PERFORMANCE given below are some of the performance criterion comparisons CriterionWindows 2000Linux Plug’n playGoodOkay System resilienceOkayDeveloping Workload management Developing StabilityLessMore Partitioning support Okay Web service support Good Web appln support is also very good with.NET Good Web appln. Support is okay

5. PERFORMANCE continues CriterionWindows 2000Linux Flexibility of commands Not goodGood ComplexityNot muchComplex due its flexibility Speed of execution Faster in web applns. Faster in simple commands 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
