Copyright and Liscences
by Matty Wacht
What is a copyright?
When a copyright expires (i.e. upon the author's death), the product is given to the public domain license and is no longer protected by copyright. Examples of this include classic literature and music.
Freeware is copyrighted work that can be copied, used, or given away for free, like iTunes or Safari. The creators generally make money off of ads placed within the product.
Shareware is work that can be copied, shared, used for free - but only for a limited time. If one wants more time to use the work, they must buy it. Microsoft's Internet Explorer program is shareware.
All Rights Reserved
All Rights Reserved works only allow purchasers to use the software according to what is on the license agreement. Some examples include Microsoft Word and the Call of Duty series.
Open Source software includes the source code with the idea that someone can improve upon the work. Firefox and Google Chrome are open-source, so users can create add-ons and extensions.
