After experimenting on Fedora for months today i ported myself fully to Arch.Arch Linux is a light weight Linux distribution.The Arch is based on simplicity, simple as stick!! The Arch Linux provides the power and combustibility than any other Linux system out there.
The Arch Linux involves installation from scratches and one can customize the OS in any way one needs to. On a fresh installation of the operating system you will only have a basic Linux system with no GUI,no sound,etc but all basic modules to run an OS. You will be greeted only by a tty where you can login as root and start building your custom OS!!!
The Arch Linux emphasis on simplicity and wants to make your system as simple as possible.By giving such a low functional operating system, the Arch wants the users to add only those packages one needs to. This makes your system light weight and much more flexible than any other Linux distribution. That is in Fedora installing the OS will give you many different packages which you may not even know what it does.There no such case in Arch.If you think you want it then you can install it.
The Arch uses a power full package manager called pacman.The pacman is a light weight package manager in which you will have access to the latest packages compared to other package managers like apt or rpm.
Final word: The Arch Linus is a definite try for intermediate and expert Linux users. Even though the installation in little bit lengthy you will surely benefit from it, you will get a clear picture of what each are meant for and so on.....Beginners are not recommended to use Arch Linux as you should have basic understanding of Linux file system and which files are meant for what and so on....
