semester 1 2012 week 7 - 9

for this week..i do the research of operating system use in the small office server appliance..

in the small office server  i use the linux as the main os of the small office server appliance..

Linux
Linux is an increasingly popular operating system that is proving to be a viable alternative to Microsoft’s Windows and Apple’s Mac operating systems. Linux is open source, which means that it is developed by a tight-knit community of developers and designed to be permanently free of charge. Because of this, there are many different types of Linux operating systems available to users. Linux is PC-UNIX in which the kernel was created for PC/AT compatibles by Linus Torvalds of Finland. The name is derived from the kernel’s creator
there are many types of linux which is;



RedHat Linux

Red Hat Linux, assembled by the company Red Hat, was a popular Linux based operating system until its discontinuation in 2004.
Red Hat Linux 1.0 was released on November 3, 1994. It was originally called “Red Hat Commercial Linux”. It was the first Linux distribution to use the RPM Package Manager as its packaging format, and over time has served as the starting point for several other distributions, such as Mandriva Linux and Yellow Dog Linux.
Red Hat Linux introduced a graphical installer called Anaconda, intended to be easy to use for novices, and which has since been adopted by some other Linux distributions. It also introduced a built-in tool called Lokkit for configuring the firewall capabilities.
As of Red Hat Linux 8.0, UTF-8 was enabled as the default character encoding for the system. This had little effect on English-speaking users, but enabled much easier internationalisation and seamless support for multiple languages, including ideographic, bi-directional and complex script languages along with European languages.
Red Hat Linux lacked many features due to possible copyright and patent problems. For example, MP3 support was disabled in both Rhythmbox and XMMS; instead, Red Hat recommended using Ogg Vorbis, which has no patents. MP3 support, however, could be installed afterwards, although royalties are required everywhere MP3 is patented. Support for Microsoft’s NTFS file system was also missing, but could be freely installed as well.

Centos

CentOS is a community-supported, free and open source operating system based on Red Hat Enterprise Linux. It exists to provide a free enterprise class computing platform and strives to maintain 100% binary compatibility with its upstream distribution. CentOS stands for Community ENTerprise Operating System. CentOS developers use Red Hat’s source code to create a final product very similar to Red Hat Enterprise Linux. CentOS is available free of charge. Technical support is primarily provided by the community via official mailing lists, web forums, and chat rooms.
CentOS version numbers have two parts, a major version and a minor version. The major and minor version numbers respectively correspond to the major version and update set of Red Hat Enterprise Linux from which the source packages used to build CentOS are taken. For example, CentOS 4.4 is built from the source packages from Red Hat Enterprise Linux 4 update 4.

Fedora

Fedora is another example of a Linux distribution. In appearance, Fedora’s desktop and standard operations are similar to those of Ubuntu and Kubuntu. Fedora is used primarily for older PCs due to its limited system requirements. The term fedora was in use as early as 1891. The fedora came into use in about 1919. Fedoras can be found in nearly any color imaginable, but black, grey, tan, brown, and red are the most popular.

Ubuntu

The most popular and widely used Linux distribution is called “Ubuntu.” Ubuntu is aimed at bringing Linux to casual computer users and is
comparable in features to Microsoft’s Windows operating system. Ubuntu is a computer operating system based on the Debian Linux distribution. Ubuntu focuses on usability and security. The Ubiquity installer allows Ubuntu to be installed to the hard disk from within the Live CD environment, without the need for restarting the computer prior to installation.
Ubuntu comes installed with a wide range of software that includes OpenOffice, Firefox, Pidgin, Transmission, GIMP, and several lightweight games (such as Sudoku and chess). Ubuntu allows networking ports to be closed using its firewall, with customized port selection available. It offers support for more than 46 languages. Ubuntu can also run many programs designed for Microsoft Windows (such as Microsoft Office), through Wine or using a Virtual Machine.

Kubuntu

Kubuntu is similar to Ubuntu in operation. The main difference is that Kubuntu uses a different type of file system than Ubuntu. They both perform the same basic functions, and both are easily accessible to casual computer users

Debian

Debian is a more complicated version of the Linux operating system. It is what the distributions Ubuntu and Kubuntu are based on, though it is not nearly as accessible to casual computer users. Debian has the ability to operate as a standard desktop computer operating system, as well as an operating system used to run computer servers

Linux Mint

           Linux Mint is a Linux distribution that was modeled after Ubuntu. As opposed to Ubuntu, which has limited functionality when first installed and requires users to pick and choose which applications to install based on their needs, Linux Mint's focus is providing all programs and drivers a user would need immediately after installation.
       zentyal
        Zentyal was developed with the aim of bringing Linux closer to SMBs and to allow them to make the most of its potential as a corporate server. It is the open source alternative to Microsoft network infrastructure products aimed at SMBs (Windows Small Business Server, Windows Server, Microsoft Exchange, and Microsoft Forefront.) and it is based on the popular Ubuntu distribution. Zentyal allows IT professionals to manage all network services such as Internet access, network security, resource sharing, network infrastructure or communications in an easy way via one single platform.
