In this week, the lecture shows the differences between propriety software, free software and creative commons.
Proprietary software is a frequently used term in the computer field. It refers to software that is owned by an individual or a company and is protected from unauthorized use by patents, trademarks and copyrights.
Free software is a matter of the users' freedom to run, copy, distribute, study, change and improve the software. This is to say, the freedom to run the program, for any purpose .The freedom to study how the program works, and change it to make it do what you wish.The freedom to redistribute copies so you can help your neighbor and the freedom to improve the program, and release your improvements to the public, so that the whole community benefits. Free software does not mean non-commercial. A free program must be available for commercial use, commercial development, and commercial distribution.

Creative Commons is a non-profit organization. It devoted to expanding the range of creative works available for others to build upon legally and to share. Renata Avila analyses that " Creative Commons gives voice to creativity, and allows us to share symbolic space within society, charting alternative routes to inclusion across the continents, in all languages."
