- 1. 1 SOFTWARE Software is a set of instruction which control the computer hardware component to compleate different task. Write Insert Go type
- 2. 2 On Off On Off Simple example: Switch On/Off Sound Sensitive device with personal command(Instruction) Sound Recorder with Recorded instruction set (Software program)
- 3. 3 Software can be categarize in different categaries Generally Eg: Application software,System Software,Malicious & harmful software License condition and copyright status Eg: Free software, Propitary Software Source code avelability Eg: Open Source software, Closed Source software Networking envirument Eg: Sever Softwaew, Client Software User functionality Eg: Application Software, Development Software
- 4. 4 Open Source Software Source code of the software, available to visible any party. Any knowledgable party can undestand internal structure of the software and how to it's implementation done.
- 5. 5 Closed Source Software Software distribute only with binary code. Source code remain as intellectual property of the developer or authorised person or company. Due to source code invisibility any party(whith out developer) can't cleary undestand internal structer and how to implement end task of the software.

- 7. 7 History of the open source software In 1960 Software provide freely with bundled of hardware devices.Cost is effect only hardware. Source code available and no restriction or copyrightes to change or distribute.
- 8. 8 In 1970 Main company in computer industry stopped, suppling free software. Person of the idustry consider software as intellectual property. Stopped providing source code. Provided only bineries with copyright restriction.
- 9. 9 Because of this new trends it introduce new cencept for software industry. Software licenses : Contract agreement between owener and user Trade secretes of ownering parties. Patents used to protect the idea behind software. Employee contract agreement with companies for there producing software.
- 10. 10 Due to this new situation of the software industry, meny of the knowledgable users (Students, Academics, Universities, Idependent Developers)Become faced huge deficulties in there fields. Unsatisfied software solution for there individual requirement. Unfix bug and malfunction. Can't improving and extending for there requirement. High cost Copyright restriction.
- 11. 11 To Resolve this problems some groups produce there own software for there specific requirnment. Eg: BSD Unix â created by computer reserch group of university Backely.
- 12. 12 In 1980 Richard Stallman was programmer in Massactusets Institute of Technology Artificial intelligency lab, step forward against the software industry situation by using community based social movement call FREE SOFTWARE FOUNDATION GNU Project.
- 13. 13 In 1990 Bill Jolitz finished reimplementing BSD Unix based free version call 386BSD. It used as based to develop other free version of NetBSD, FreeBSD, OpenBSD, DragenflyBSD etc. Linus Torvalds university student of computer science in Finland develop unix kernel called Linux. Linux Kernel and free software foundation's GNU project altogether released compleate open source operating system called GNU-Linux operating system.
- 14. 14 Tim Berner-Lee invent the http protocal and www (world wild web), making internet more easily accessible and useful. Richard Stallman Bill Jolitz Linus Torvalds Tim Berner-Lee
- 15. 15 In 1998 start new group of movement call open source initiative. This OSI license terms more ''business friendly'' than free software. They call it is alternative of free software for business purpose. After that open source initiave and free software foundation working with some project together but move forward in different path ways.
- 16. 16 Open Source Software (OSI License) â Opensource software is a computer software which it's source code made available with a license, provided by the copyright holder with given rights to study change and distribute the software to any person to any purpose without any restriction.
- 17. 17 Features of Open Souerce Software Source code is avaliable. Users should be agreed the license in which copyright provider given rights. Can be use and distribute any person without restriction. Can be use any purpose without limitation. License can't distribute as viral nature. Vender can't block or lock in the software. Relatively low cost. Relatively security level is high. High quality software with lower rate of bug and malfunction.
- 18. 18 Open Source Initiative Licenses Requirnment Free distribution Source code avaliable with the software Allowed modification and derived work Intrigrity of author's source code â To distribute the modification may required patch files No discrimination against people No discrimination agenst fields of endeavour Distribution with license License not specific to product License can't restrict other software distributed with this one License is technology natural.No restriction for specific technology or hardware.
- 19. 19 Free Open Source Software Execute the software program without restriction. Study the source code and able to change it. Distribute copies without restriction. Freely distribute changes of the software as new version.
- 20. 20 Features of FOSS Nobody can't estimate the cost for sourcecode Totally free or low cost Changes with new software version should be release and distributeterms of original software licenses License distribute as viral nature
- 21. 21
- 22. 22 Continuity of OSS and FOSS Foundation codes created by free of charge by some groups and communities. Developer maintain repository for distribution and maintain software. Any body has a knowledge can be understand internal structure of the executable software. Knowledgable person can be change and modify the source code for improve the end task.
- 23. 23 Anybody developed new modification can be release and distribute as new version or mutant (fork) of sorce software. If the maintainers of origenal source software, accept these modification they release patches for new version. These activities continually done cyclicly in OSS and FOSS environment and it cause to rapid development of the software.

- 25. 25 Free & open Source Operation System Free BSD based Derivatives Midnight BSD
- 26. 26 GNU/Linux Based Derivatives Gentoo Limux
- 28. 28 GNU / Linux Operating System After Linus Torvalds developed linux kernel, fulfill remaning missing part of FSF GNU project's free opensource operating system. A new system call GNU / Linux operating system distribute with GNU's Free software license. Since first release of GNU / Linux operating system, due to it's rapid development nature, many derivatives and mutent (fork) develop for different technologies as the embedded systems.

- 30. 30 Update & Package Distribution in Linux Compress source code or individual software package installing ,configuring, building ,updating should be done manualy. Package managers Package management system is a collection of software tools that automates the process of installing ,upgrading ,configuring and removing computer programs for a computer oprating system in a consistent manner.
- 31. 31 There can be divided four basic categoris of package management file formats in Linux . dpkg - deb Fomat eg : Ubuntu ,Linux mint ,Dabian & its derivatives ebuld - eg : Gentoo & its derivatives PET - eg : Puppy linux & derivatives RPM - eg : Redhat ,Fedore ,CentOS ,Suse Linux
- 32. 32 Application for Linux Based OS General Purpose Application Office Work â Open Office 2D Graphics & Photo edting â Gimp Web browsing â Firefox ,Chrome Ebook reading â xpdf Virtual OS using â Virtual box 3D Graphics and animation â Blender Video player â VLC , Totem videos Web cam recoding â Cheese Cd ,Dvd burning â Brasero Audio Editing â Audacity Video Editing â Open shot Desktop recording â Handbreak, Record my desktop Windows app using - Wine
- 33. 33 Specific purpose (special fields) application There are many specific purpose free open source Application can be install in linux based operating systems. Engineering field Architectural and planing Software developing Web developing Sound and music composting Educational and learning
