Linux Directory Structure § Store drives § Accessing data using folders § Root directory: § beginning of file system 11 -21

Subdirectories Examples of Subdirectories /root directory, starting point of the directory tree /home (private) directories of users /dev. Device files that represent hardware components /etc Important files for system configuration /etc/init. d Boot scripts/usr/bin. Generally accessible programs 11 -22

Why Use Linux? • Costs less • Stable • Reliable • Extremely powerful 11 -23

LINUX VS WINDOWS 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 ØKeeping up to date By Upgrading Linux upgrades faster than Windows ØCompatibility Linux is Backward Compatible unlike Windows 11 -30

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

Linux vs. Windows • Application Differences ØNo commercial word processor for Linux, which matches the quality for Windows 11 -32

End-User Differences 11 -33

• Proprietary vs. Open Source ØWindows is a Proprietary Technology Applications will only work on Windows ØLinux – 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 ØHead to head competition ØUsed side by side as servers ØBoth handled daily workload for several small business operations ØLinux with hardware disadvantage supported a community of users 3 times size of NT’s 11 -36

In The Commercial Arena ØSystem Administration – Most significant difference ØLinux – tougher environment ØLinux requires learning multi-user issues built into Unix-file permissions ØNT – easier environment ØNT requires less effort to get a starter server up and running ØBut in NT you have to solve multi-user issues for each and every subsystem 11 -37

In The Commercial Arena ØNT – graphical interfaces, wizards and easy-to -grasp metaphors ØBut as server chores become more customized, NT cannot handle it ØLinux – textual interface (with X-Window) ØBut for complex jobs, Linux gives a powerful set of tools 11 -38
