Copyright & Licenses

What are the 5 types of licenses?

What is a Copyright?

A copyright is a collection of rights granted to the author of a piece of work (book, song, video, software…)

1. Public Domain

Public domain isn’t protected by copyright law because the copyright has expired, it was created using public money, or it was donated to the public. Some examples of public domain include classic literature (Shakespeare), older classical music. Both copyrights have expired.

Freeware is copyrighted work that you can copy, use, or give away for free. An example of freeware is iTunes, since it’s free, and there is no other version.

Shareware is copyrighted work that you can copy, use, or give away for free, but only for a limited time. Shareware is very common; it shows up in forms such as 30 day free trials and lite apps. You can purchase the full version, but shareware lets you try it first.

All Rights Reserved

All Rights Reserved allows the purchaser to only use the software according to the details spelled out in the license agreement. It can say pretty much anything. One example of this would be Microsoft - it originally said that software could be downloaded to only one computer, but then changed it to 3 after realizing that families needed to share. Most software bought at Best Buy or other stores would also be considered All Rights Reserved.

Open Source

Open Source is software that includes a source code with the idea that someone can improve it. One example of this is Google Chrome - it allows users to make changes and personalize their homepage.
