For the Debian system it is a bit look like a pyramid. However at the base is a Linux. Then at the top of all are basic tools and mostly from GNU. Then the Debian developers act as architects and for the coordinators which is we should carefully organizing about system and fitting everything together to an integrated stable operating system which is known as Debian GNU/Linux.
The Debian Linux is creating by an all-volunteer internet based development. They are around hundreds of volunteers working on it. Most of them are in charge of small particular of the software packages and those very familiar with the software they will package. These volunteer they work together is following a strict set of guidelines governing how packages are assembled. For this guideline it is developed from the cooperatively discussions on internet mailing lists.
The system requirement for PC to run this Debian Linux operating system is must at least giving 4MB memory and 35MB of available hard disk space. If users want to essential full installation, it needs 800MB. To install everything it needs around 2GB.
Fedora core: The Fedora core is the basic Linux operating system, it designed especially for developers and hobbyists. As the tested of red hat enterprise Linux, it allow enterprise user to view the latest features before they are released for the enterprise and Fedora Linux is also a complete distribution. It includes a wide variety of command, utilities and applications. In addition the Fedora is primarily geared toward desktop users, although it is a little adapting but also can be used to run server computers. For this Fedora is designed to let user easy to be use. If anyone using the windows or Mac OS will feel right at home.
Moreover, the Fedora focus largely on the desktop which is it provide the powerful office suite by default, example, as well as some excellent pieces of internet software. And also the Fedora works "straight out of the box". When user installed, it should be ready to use without any further work.
System requirement for the PC to run on Fedora core is Pentium-class- Intel-compatible 32-bit, 200 MHZ, then for the RAM it required at least 256 MB for GUI mode and the hard disk it minimum require 1GB out of 100MB free space.
Gentoo Linux: This Gentoo Linux is started by Daniel Robbins with the name "Enoch" in 199. After that it change the name to "Gentoo" cater due to speed increase as a result of EGCS adoption. Then the first version of Gentoo Linux 1.0 was released on day 31 March 2002. Besides that, the Gentoo Linux is referred as a Source Based Distribution" which means that build all the software will directly use from "Source Code". So through this source code developers are able to read and adjust, but computer cannot understand the source code, so that in order to make computer understand source code it need to compile into binaries then computer only able to understand it.
Other than that, Gentoo Linux is a special flavor of Linux that can automatically optimized and customized for any applications and the Gentoo Linux can become an ideal secure server, development workstations, professional desktop, gaming system, embedded solution or other, this is because it near unlimited adaptability, so we calling Gento Linux as a meta distribution.
Arch Linux: At the beginning the Arch Linux was started in 2001 by Judd Vient when he discovered he could not find any distribution that met his ideals. By the way Arch has taken the ideas from Debian and Gentoo, which has gradually evolved into the simple, powerful and stable distribution together with active user and developer population.
Arch Linux is an open source and an i686-optimized Linux of the distribution that was originally based on the ideas from CRUX, this distribution is developed by Per Liden. For the arch it is fast, lightweight flexible and simple. Compared the lightweight to RedHat it is more simple and design make it easy to be extend and mode into whatever kind of system that user build it.
Moreover, Arch Linux also strives to maintain latest stable version of those software. And it also strives to use some newer features that are available for Linux users such as ext3/reiserfs and devas support.
