• 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
Criterion Windows 2000 Linux
Ease of use Good Okay
User assistance Application specific Command specific
History No Good
Technical support Good OSS
Pricing High mid and low range
4
PERFORMANCEgiven below are some of the
performance criterion comparisons
Criterion Windows 2000 Linux
Plugn play Good Okay
System resilience Okay Developing
Workload management Developing Developing
Stability Less More
Partitioning support Okay Okay
Web service support Good Web appln support is also very good with .NET Good Web appln. Support is okay
5
PERFORMANCE continues
Criterion Windows 2000 Linux
Flexibility of commands Not good Good
Complexity Not much Complex 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.

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 didnt 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
