What is Open Source SW? q Open source SW(OSS) is the computer SW that is available in source code form under certain licenses. q Users of OSS are permitted to use, copy, study, change, improve and even redistribute those OSS freely. q โFreeโ does not mean โFree of Chargeโ but โFreedomโ or โLibertyโ I. Overview of Open Source SW 5 Freedom Of Software Freedom of Redistribute Freedom of Modify Freedom of Copy Freedom of Use

Benefits of Open Source SW 7 q Benefits of Open Source Software ยง Empower people, save money, save resources, increase stability, access to source code, access to skilled community of developers Develop the society by sharing technology & outcomes!! 1. Technological Aspects 2. Economical Aspects 3. Business Aspects 4. Other Aspects Rapid development of high-class SW Increased stability by skilled community review Reduce technological gap to leading proprietary SW company Internalize outside SW developer resources Very low adoption cost Reduce SW development cost Easy to customize Reuse successful story Extend companyโs products portfolio Open up new market by providing diversified services & products Improve brand image of company Reduce energy Self-Satisfaction Help society I. Overview of Open Source SW
