Introduction to Linux Operating System“UBUNTU”

Operating System- it is responsible for the management and coordination of activities of hardware and software.

Examples:

Microsoft Windows 98

Microsoft Windows XP

Microsoft Windows Vista

Fedora Core

Ubuntu

SUSE

MAC OSX

Kernel- Central Component of OS manages system resources(communication between software and hardware.

Examples:

UNIX kernel

LINUX kernel

Microsoft Windows kernel

MAC OS kernel

A kernel connects the application software to the hardware of a computer.

3 Kinds of Software Distribution

Commercial SoftwareSharewareFree and Open Source

Free and Open Source Software also F/OSS, FOSS, or FLOSS (for Free) is software which is liberally licensed to grant the right of users to study, change, and improve its

design through the availability of its source code.

Unix- is a computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe

Ossanna.

FOSS

- (commonly pronounced IPA: /ˈlɪnəks/ in English; variants existcite_ref-0cite_ref-0[1]) is a generic term referring to Unix-like computer operating systems based on the Linux kernel. Their development is one of the most prominent examples of free and open source software collaboration; typically all the underlying source code can be used, freely modified, and redistributed by anyone under the terms of the GNU GPLcite_ref-1cite_ref-1[2] and other free licenses.

LINUX

Linux kernel- is an operating system kernel used by a family of Unix-likecite_ref-README_4-0cite_ref-

README_4-0[5] operating systems.

-is released under the

GNU General Public License- is a widely used free software license originally written by Richard Stallman for

the GNU project.

The name "Linux" comes from the Linux kernel, originally written in 1991 by Linus Torvalds.

UBUNTU

-is a computer operating system based on Debian GNU/Linux. Its name comes from the Zulu word "ubuntu", translated as "humanity to others", describing the ubuntu philosophy: "I am what I am because of who we all are", a positive aspect of community. Ubuntu's goals include providing an up-to-date, stable operating system for the average user, with a strong focus on usability and ease of installation. Ubuntu has been rated as the most popular Linux distribution for the desktop, claiming approximately 30% of desktop Linux installations in 2007.

Ubuntu is sponsored by the UK based company Canonical Ltd., owned by South African entrepreneur Mark Shuttleworth. Instead of selling Ubuntu for profit, Canonical creates revenue by selling technical support. By keeping Ubuntu free and open source, Canonical is able to take advantage of the talents of outside developers in Ubuntu's constituent components without developing the entire operating system itself.

Ubuntu was initially forked from the Debian project's code base.cite_ref-history_7-0cite_ref-history_7-0[8] The aim was to release a new version of Ubuntu every six months, resulting in a more frequently updated system. Ubuntu's first release was on October 20, 2004.

Ubuntu is currently funded by Canonical Ltd. On July 8, 2005, Mark Shuttleworth and Canonical Ltd announced the creation of the Ubuntu Foundation and provided an initial funding of US$10 million. The purpose of the foundation is to ensure the support and development for all future versions of Ubuntu.

PHILOSOPHYOur work is driven by a philosophy on software freedom that aims to spread and bring the benefits of software to all parts of the world. At the core of the Ubuntu Philosophy are these core philosophical ideals:

1. Every computer user should have the freedom to download, run, copy, distribute, study, share, change and improve their software for any purpose, without paying licensing fees.

2. Every computer user should be able to use their software in the language of their choice.

3. Every computer user should be given every opportunity to use software, even if they work under a disability.
