15. Configuring Linux System • Selecting a language • Choosing automatic or manual partitioning • Type of software to install • Choosing which drive to boot from

16. Configuring Linux (continued) 5. Adjusting the time settings 6. Configuring the hardware aspect of the system 7. Creating the root password (for the Administrator), and user accounts 8. Hardware configuration

17. Working with Linux Graphical User Interface • X Window System • SuSE KDE SuSE

18. Software Applications • OpenOffice: word processing, spreadsheets, drawing • Adobe Acrobat Reader • Konqueror: The KDE File Manager and Web Browser • Kmail: The KDE Mail Application • Evolution: An Email and Calendar Program • Sound Applications

19. Software Applications (continued) • TV, Video, Radio, and Webcam • K3b: The KDE Burning Application • Digital Cameras • Kooka: Scanning Application • Graphics with the GIMP • Shell system

20. Working with the “Shell” • Executes user commands • Command element • Command name • parameters

21. Linux Directory Structure • Store drives • Accessing data using folders • Root directory: • beginning of file system

22. Subdirectories Examples of Subdirectories /root directory, starting point of the directory tree /home (private) directories of users /devDevice files that represent hardware components /etc Important files for system configuration /etc/init.d Boot scripts/usr/binGenerally accessible programs

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

24. LINUX VS WINDOWS

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

26. Financial Differences

27. Linux vs. Windows

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

29. Technical Differences

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

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

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

33. End-User Differences

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

35. 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

36. 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

37. 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

38. 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

39. In The Commercial Arena • NT – easy for non-programmer • Linux – programmer-based culture

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