Why Use Linux?
• Costs less
• Stable
• Reliable
• Extremely powerful

25. 11-25
LINUX VS WINDOWS

26. 11-26
• Financial Differences
• Technical Differences
• End-User Differences

27. 11-27
Financial Differences

28. 11-28
Linux vs. Windows
COST
LINUX WINDOWS
Online Downloads Free Not Available
Retail Price, CD $50 $300

29. 11-29
• Cost for Businesses
–Companies have to spend millions for
licenses for ever individual windows
computer
–For Linux companies don’t have to spend
anything

30. 11-30
Technical Differences

31. 11-31
Linux vs. Windows
Keeping up to date
By Upgrading
Linux upgrades faster than Windows
Compatibility
Linux is Backward Compatible unlike
Windows

32. 11-32
Linux vs. Windows
Features Provided
Both support Dynamic Caching
Both have Multi-user Support

33. 11-33
Linux vs. Windows
• Application Differences
No commercial word processor for
Linux, which matches the quality for
Windows

34. 11-34
End-User Differences

35. 11-35
• Proprietary vs. Open Source
Windows is a Proprietary Technology
Applications will only work on Windows
Linux – Open Source

36. 11-36
Linux
Complete information needed for
download
Technical help – Available on Internet
(user must be comfortable with UNIX
system)
Windows word processor is better than
Linux

37. 11-37
Linux vs. Windows
Head to head competition
Used side by side as servers
Both handled daily workload for several
small business operations
Linux with hardware disadvantage
supported a community of users 3 times
size of NT’s
In The Commercial Arena

38. 11-38
In The Commercial Arena
System Administration – Most significant
difference
Linux – tougher environment
Linux requires learning multi-user issues
built into Unix-file permissions
NT – easier environment
NT requires less effort to get a starter server
up and running
But in NT you have to solve multi-user issues
for each and every subsystem

39. 11-39
In The Commercial Arena
NT – graphical interfaces, wizards and easy-
to-grasp metaphors
But as server chores become more
customized, NT cannot handle it
Linux – textual interface (with X-Window)
But for complex jobs, Linux gives a powerful
set of tools

40. 11-40
In The Commercial Arena
NT – easy for non-programmer
Linux – programmer-based culture

41. 11-41
Conclusion
“When is it best to use Linux and when
should some other operating system be
preferred?”
It all depends on the user
