Studying Main Differences Between Linux & Windows Operating Systems
Lecturer/ Hadeel Tariq Al-Rayes

Abstract—Comparisons between the Microsoft Windows and
Linux computer operating systems are a long-running discussion topic within the personal computer industry.

This makes more sense because in Linux, there is a single filesystem layout, starting at root (“/” or “slash”) and everything is located beneath it; for example, user files go in /home (“slash home”). If you want to keep your user files on a separate disk or partition, you don’t have an E: drive; instead you simply mount your separate disk as /home. 2. There is no registry Linux doesn’t use a single database of configuration options, the way Windows does with its registry. Instead, there are many individual configuration files, typically in a simple text format (but increasingly in XML), that can be edited by hand using a text editor if need-be. You’ll find the system-wide configuration files in the /etc directory; your user-specific configuration files will typically be located in hidden directories in your home folder. This is better than Windows because it means that there is no single point of failure for system configuration. If one configuration file becomes corrupt, only that function breaks and everything else works fine. It also makes it easy to backup configuration files — it’s the same as copying all other files — and to troubleshoot problems: often if you ask for help on the internet, the first thing people will ask for is a copy of your configuration files. 3. Software comes from the repos, not CDs or websites In the Windows world, if you need to find a program to perform a task you’ll typically have to Google for it and install it using its own installer. Or, you can go to the store and

INTRODUCTION

Linux is a Unix-like operating system that was designed to provide personal computer users a free or very low-cost operating system comparable to traditional and usually more expensive Unix systems. Linux has a reputation as a very efficient and fast-performing system. Linux's kernel (the central part of the operating system) was developed by Linus Torvalds at the University of Helsinki in Finland. To complete the operating system, Torvalds and other team members made use of system components developed by members of the Free Software Foundation for the GNU Project. The researcher tried to give the main differences between the previous operating system and windows from many view points.
