Open Source Technology: Open Source Technology Represented By : Chetan S. Shewale (3 rd Information Technology) PowerPoint Presentation: introduction : Open-source software is software whose source code is published and made available to the public, enabling anyone to copy, modify and redistribute the source code without paying royalties or fees. Open source code can evolve through community cooperation. These communities are composed of individual programmers as well as very large companies. Many of these individuals programmers who start an open source project usually end up as large companies with open source programs. PowerPoint Presentation: open vs. closed source s/w : Open-source software is based on the idea that the user cannot only view but also can change the source code of the existing application. Closed-source software is hidden to prevent the user either viewing or changing the code. PowerPoint Presentation: open vs. closed source s/w : After initial production, open source software is released to the development community and undergoes a secondary phase of evolution. It is scrutinized by thousands of professional developers across the globe who highlight bugs and security glitches in the software. Closed source software is developed in isolation with a small team of developers. It isn't possible to build a team of hundreds to check the code because the code is deemed proprietary and secret. PowerPoint Presentation: Non-proprietary software which may or may not be used commercially. Source code is generally made available. License terms differ from proprietary software license terms For open-source software development many online forums & blogs are available so that many developers can come together and can produce a new one or can help each others. FEATURES : PowerPoint Presentation: Advantages of O.S.T. : Lower total cost of ownership. Reduced dependence on software vendors. Open source software gives you the power to control your software's code. You have the right to modify the code to suit your requirements. Anyone can easily modify the code of software to produce a new featured software from existing one or to reduce the functionalities of existing one. PowerPoint Presentation: Disadvantages of O.S.T. : 1. Most open source software applications are not reliable. No guarantee of updates since you are not paying for the open source software nobody is bound to give you regular updates. You can get stuck with the same old version for years without ever getting an update. PowerPoint Presentation: No one is bound with you for maintenance and support like as legal software vendors, if any error in working of software occurs. 4. No warranties regarding to viruses and performance. Disadvantages of O.S.T. : PowerPoint Presentation: myths about Open source s/w : It's all about Linux versus Windows, with Red Hat as yet another challenger to Microsoft. Open-source Software Isn't Reliable or Supported. Big companies don't use open source software. There's no money to be made on free software. Open Source is playing catch up to Microsoft and the commercial world. PowerPoint Presentation:
