One of the most visible rights that the author of a work has, is the copyright over his work. Almost everything that is published, whether eletronically or not, is copyrighted. In general, a work is copyrighted when it is created, and it is not necessary to apply for copyright.

In any case, when a work is copyrighted, others may not use or redistribute the work without the permission of the author. This permission is typically called a license for the work.
