LINUX WINDOWS Vs.

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.

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

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

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

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

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

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

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

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

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

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

Information Protection and Security Access control regulate user access to the system Information flow control regulate flow of data within the system and its delivery to users Certification proving that access and flow control perform according to specifications

Financial Differences COST LINUX WINDOWS Online Downloads Free Not Available Retail Price, CD $50 $300

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

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

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

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

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

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
