3. What is an operating system?
A program that controls the execution of application programs
An interface between applications and hardware.
Makes the computer more convenient to use
Manages the resources of the computer
Allows resources to be used in an efficient manner
Examples of OS??

4. Services Provided by the OS
Program execution
Access to Input/Output (I/O) devices
Disks, screens, keyboards, mice
Printers, cameras, speakers, etc.
Controlled access to files
System access
Sometimes: Program development
Compilers, editors and debuggers

5. Introducing Linux
Linux was originally built by Linus Torvalds at the University of Helsinki in 1991.
Linux is a Unix-like, Kernal-based, fully memory-protected, multitasking operating system .
Open Source Operating System.
Free Software
Source Code Available
It runs on a wide range of hardware from PCs to Macs.

6. Introducing Windows
First version of Windows – Windows 3.1 released in 1992 by Microsoft.
Windows is a GUI based operating system
It has powerful networking capabilities, is multitasking, and extremely user friendly

13. Fundamental Difference between Linux & Windows
One fundamental difference between the two systems is the fact that Linux is "open source".

14. Comparing Applications
Linux falls short in the number of different applications available for it.
There are much more various applications available for Microsoft since the population of Window’s users is greater than Linux’s
Since Microsoft is more popular, the Hardware products are aimed at the biggest market – Windows, such that the product would be sold and used widely

15. Comparing Applications Cont.
Linux programs distributes freely since they are not developed by commercial software companies, but instead are created under the GNU Public License, which makes the software free
Linux software lacks the GUI and is therefore not “liked” by many users

16. Comparing Applications Cont.
Windows has its own share of problems – the fact that some software is not compliant for different versions of windows (i.e. Windows 95/98) and many times the GUI concept is overused such that command arguments cannot be passed to the program

17. Linux advantages in Kernel and the OS environment
Linux requires 386 architecture to run. Thus, it is compatible with any improved architecture such as 486, Pentium, Pentium Pro, etc
There are drivers available for much many types of hardware devices

18. Contd…
Linux program installation seems to be easier since it only requires a restart when hardware device has been changed
Linux supports multiple copies of the Kernel on the system such that if an error is encountered and the Kernel becomes corrupted, a different copy of the Kernel can be used to boot up the system

19. Reliability
OS it must not crash, even under extreme loads. OS should process requests even if the operating system or hardware fails
Windows seems to be less stable even though the latest versions of Windows – 2000 and XP are far more improved than the incredibly buggy Windows 95

20. Security
Linux seems to be more prepared for protecting itself because of the beginning developments of Linux, UNIX, and FreeBSD which were aimed at top notch security
Linux allows does not create registry keys in a way Windows does allowing a user to browse installed components registry keys, which contain important information

21. Security contd…
Linux is more virus proof since viruses – malicious programs either cannot be run automatically on the Linux machine, or simply are not capable of being executed on a 386 architecture
Windows is often known for a large amount of loop holes

22. Financial Differences

23. Financial Differences
Companies have to spend millions for licenses for ever individual windows computer
For Linux companies don’t have to spend anything

24. Technical Differences
Keeping up to date: Linux upgrades faster than Windows
Compatibility: Linux is Backward Compatible unlike Windows.

25. Technical Differences
Features Provided:
Both support Dynamic Caching
Both have Multi-user Support
Application differences
No commercial word processor for Linux, which matches the quality for Windows

26. End-User Differences Proprietary vs. Open source
Windows is a Proprietary Technology
Applications will only work on Windows
Linux – Open Source

27. FILE SYSTEM Implements long-term store
Information stored in named objects called files
OS typically offers the following file operations:
creating, deleting, renaming
reading, writing
locking, unlocking

28. FILE SYSTEM Contd… NTFS v EXT3 We have used EXT2 and EXT3 as the
Linux FS due to their popularity
NTFS is the primary XP FS
– Not backwards compatible with Win2k
