CentOS is a free operating system based on Red Hat Enterprise Linux (RHEL). 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 is the most popular Linux distribution for web servers with almost 30% of all Linux web servers using it.

Structure
Red Hat Enterprise Linux is available only through a paid subscription service that provides access to software updates and varying levels of technical support. The product is largely composed of software packages distributed under either an open source or a free software license and the source code for these packages is made public by Red Hat. CentOS developers use Red Hat’s source code to create a final product very similar to Red Hat Enterprise Linux. Red Hat’s branding and logos are changed because Red Hat does not allow them to be redistributed.

CentOS is available free of charge. Technical support is primarily provided by the community via official mailing lists, web forums, and chat rooms. The project is not affiliated with Red Hat and thus receives no financial or logistical support from the company; instead, the CentOS Project relies on donations from users and organizational sponsors.

Versioning scheme
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. Since mid-2006, starting with version 4.4 (formally known as Red Hat Enterprise Linux 4.0 update 4), Red Hat has adopted a versioning convention identical to that of CentOS, e.g., Red Hat Enterprise Linux 4.5.

Architectures
CentOS supports only the x86 architectures:
• x86 (32-bit)
• x86-64 (AMD’s AMD64 and Intel’s EM64T, 64-bit)
The following architectures are not supported by CentOS (as of version 5):
• IA-64 (Intel Itanium architecture, 64-bit) (beta support since CentOS 3)
• PowerPC/32 (Apple Macintosh and PowerMac running the G3 or G4 PowerPC processor) (beta support since CentOS 3)
• IBM Mainframe (eServer zSeries and S/390) (not CentOS 5)
• Alpha (CentOS 4 only)
• SPARC (beta support since CentOS 3)

Bootable media version• A Live CD version of CentOS is available at mirror.centos.org.
• A Live USB of CentOS can be created manually or with UNetbootin.

History
In July 2009, it was reported that CentOS’s founder, Lance Davis, had disappeared in 2008. Davis had ceased contribution to the project but continued to hold the registration for the CentOS domain and PayPal account. In August 2009, the CentOS team reportedly made contact with Davis and obtained the centos.info and centos.org domains.

The article will provide a user with information on Lubuntu. It will also include a brief history of Lubuntu.

Lubuntu is a lightweight Linux operating system based on Ubuntu but using the LXDE desktop environment in place of Ubuntu’s Unity shell and GNOME desktop. Lubuntu received official recognition as a formal member of the Ubuntu family on 11th May 2011, commencing with Lubuntu 11.10, which was released on 13 October 2011.

Like Xubuntu, Lubuntu is intended to be a low-system-requirement, low-RAM environment for netbooks, mobile devices and older PCs. The tests reveal that it can use half as much RAM as Xubuntu. This is why Lubuntu is considered to be an attractive choice for installing on older hardware being refurbished for charitable distribution. The name Lubuntu is a portmanteau of LXDE and Ubuntu. LXDE stands for Lightweight X11 Desktop Environment.

The LXDE desktop was first made available for Ubuntu in October 2008, with the release of Ubuntu 8.10 Intrepid Ibex. These early versions of Lubuntu, including 8.10, 9.04 and 9.10, were not available as separate ISO image downloads, and could only be installed on Ubuntu as separate lubuntu-desktop packages from the Ubuntu repositories. LXDE can also be retroactively installed in earlier Ubuntu versions.

In February 2009, Mark Shuttleworth invited the LXDE project to become a self-maintained project within the Ubuntu community, with the aim of leading to a dedicated new official Ubuntu derivative to be called Lubuntu. In March 2009, the Lubuntu project was started on Launchpad by Mario Behling, including an early project logo. The project also established an official Ubuntu wiki project page, that includes listings of applications, packages, and components.

On 30 December 2009 the first Alpha 1 “Preview” version ISO for Lubuntu 10.04 Lucid Lynx was made available for testing, with Alpha 2 following on 24 January 2010. The first Beta was released on 20 March 2010 and the stable version of Lubuntu 10.04 was released on 2 May 2010, four days behind the main Ubuntu release date of 28 April 2010.

Lubuntu 10.04 was only released as a 32-bit ISO file, but users could install a 64-bit version though the 64-bit Mini ISO and then install the required packages. Lubuntu 10.04 was not intended to be a long-term support release, unlike Ubuntu 10.04 Lucid Lynx, and was only going to be supported for 18 months.
