11-23

11-24

• Financial Differences
• Technical Differences
• End-User Differences
11-25

Financial Differences
11-26

Linux vs. Windows
COST
LINUX WINDOWS
Online Downloads Free Not Available
Retail Price, CD $50 $300
11-27

• Cost for Businesses
– Companies have to spend millions for licenses for ever individual windows computer
– For Linux companies don’t have to spend anything
11-28

Technical Differences
11-29

Linux vs. Windows
 Keeping up to date
By Upgrading
Linux upgrades faster than Windows
 Compatibility
Linux is Backward Compatible unlike
Windows
11-30

Linux vs. Windows
Features Provided
 Both support Dynamic Caching
 Both have Multi-user Support
11-31

Linux vs. Windows
• Application Differences
 No commercial word processor for
Linux, which matches the quality for
Windows
11-32

End-User Differences
11-33

• Proprietary vs. Open Source
 Windows is a Proprietary Technology
Applications will only work on Windows
 Linux – Open Source
11-34

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
11-35

Linux vs. Windows
In The Commercial Arena
 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
11-36

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
11-37

In The Commercial Arena
 NT – graphical interfaces, wizards and easyto-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
11-38

In The Commercial Arena
 NT – easy for non-programmer
 Linux – programmer-based culture
11-39

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