Free and Open Source Software

  1. 1. FREE AND OPEN SOURCE SOFTWARE
  2. 2. WHAT IS F.O.S.S. ?  Free and open source software can be classified as free software and open source software.That is anyone is freely licensed to use, study and change the software in any way.  The source code is openly shared so that the people freely are encouraged to voluntarily improve the design of software.  This is in contrast to proprietary software, where the software is under restrictive copyright and the source code is hidden from the user, so that the right holders (the software publishers) can sell binary executable file.
  3. 3. FREE & OPEN SOURCE SOFTWARE  There are two terms to separate “free” and “open source” in FOSS.  Free as in freedom of speech not as in free things.  Open mainly points to Open Source Code of the program, available for others.  So free and open source software is in some ways free but the source code is available for analysis.
  4. 4. OPEN SOURCE ALTERNATIVES Proprietary programs  Microsoft Windows  Internet explorer or Google Chrome  Microsoft Office  Adobe Photoshop  iTunes andWindows media player  skype Open source alternative  Linux Mint or BOSS Linux  Firefox or Chromium  Open Office or Neo Office  GIMP  Songbird andVLC media player  QuteCom
  5. 5. FREE SOFTWARE AND OPEN SOURCE SOFTWARE free software  free software is a software for which every one has a right not only to inspect and study the source code but also to use it for any desired purpose without monitory or other restriction.  free software is a good, morally right, thing to do. open source software  open source is a software whose source code is freely available. that is with out any requirement for payment or any other obstacles for any one to inspect and study.  Open source software is more or less indifferent to moral issues concerning software sharing.
  6. 6. MYTHS ABOUT OPEN SOURCE (FOSS STANDS FOR FREE AND OPEN SOURCE SOFTWARE)  FOSS is free.  FOSS isn't reliable or supported.  Making a software open source, anyone can change it.  The open source license is too liberal.  if you make your software open source, volunteer coders will fix all of your problems for free.
  7. 7. ADVANTAGES OF OPEN SOURCE Availability of source code. 1. source code to understand and learn from. 2. do not have to reinvent the wheels. 3. free as in freedom Less dependent on vendor 1. can choose additional support. 2. can fix bugs and adopt to change in requirements as well as technology. Quality and customizability in open source is better. Costs is much less than proprietary softwares.
  8. 8. OPEN SOURCE DEVELOPMENT MODEL
  9. 9. LINUX OPERATING SYSTEM  Linux is a computer operating system assembled under the model of free and open source software development and distribution.  originated in GNU Project, initiated in 1983 by Richard Stallman, in the free software foundation. More than 90% of today's supercomputers use Linux. It powers around 4.8% of today's modern computers.Thousands of distributers are available like. 1. Debian 2. Open SUSE 3. Fedora 4. BOSS Linux
  10. 10. OPEN SOURCE PROGRAMMING LANGUAGES  open source programming language are those that are released under open source licenses  open source programming languages are  Perl a general purpose programming languages.  PHP a scripting language suited for web .  Python a general purpose programming languages.  Ruby a general purpose programming languages.  PHDL hardware discription language used for PC board design.  Tk/Tcl a scripting language.
  11. 11. POPULARITY OF APACHEWEB SERVER
  12. 12. CONSLUSION  FOSS gives common platform for sharing ideas and putting them into action by developers or other people who wishes to improve a product/software.  We are in open source revolution where people collaborate to create, produce software or technology.  Based upon the key advantage of open source technology, we can finally conclude the open source deserves the increasing popularity.  GNU General Public Licenses http://www.gnu.org  Open source licenses http://opensource.org/licenses  Open source initiative and information http://opensource.org  Repository of open source software http://sourceforge.net  open source software development http://github.com
