Copyright Terminology

Public domain
Items placed in the public domain are free of all restrictions.

Freeware or "Copyleft"
These items are protected by copyright, but the owner has given permission for free non-commercial distribution. You should read the copyright terms to determine if the author has retained any distribution rights. For example, many "freeware" copyrights require you to obtain permission before including the software in a commercial product.

Shareware
These are commercial programs distributed on the "honor" system. You are permitted to copy the program and use it for a specific time period (typically 30 days). If you decide to keep the program, you must then pay a shareware fee to the copyright holder. Shareware has become a popular method for small software publishers since it bypasses conventional marketing channels.

Demoware
Demoware are crippled copies of commercial software. They permit you to test out the program, but you must purchase the software before you gain full functionality. For example, the demoware may be identical to the full product except that it cannot print or save documents.

Copy Protected
Some copyrighted software includes special coding that prevents successful copying. This can take the form of an encryption key, use of a hardware enabler, or use of a special key disk. In recent years, copy protection has fallen into disfavor since it often introduces many complications for legitimate users

It is important to note that copy protection is NOT the same as copyright. Even if an item is not copy protected, it may still be copyrighted and therefore illegal to duplicate the material.
