3.2 Software

Licensing: shareware, public domain, freeware, proprietart and open source software


This is software that is given to users that requires no payment. Shareware can be obtained as a downloaded from a web site or a CD with other things such as a magazine. Most of the times shareware is given out as a free trial version of a program which can consist of a limited time of usage or limited use of the program’s features. Other times the owner will ask for donations, which are of course voluntary.
The Source code of shareware programs are not normally given which means the users can’t change or upgrade the Software.

Public domain

Public domain is when anything cannot be restricted from the public and is free for the public to use.
This means that anyone can use it and does not have to pay, or do anything else to use it.


Freeware is software that is free he the sense that there is no cost to use it this is different from free software /open source. Freeware can also be free ware but doesn’t mean that it is. Most of the time owners will have a restriction like “free for personal usage and non-commercial use only.”


The definition for proprietary that it is owned by someone .In software terms it is any restrictions that the owner puts on it. This can be many different things, but most of the time proprietary software will have restrictions on the source of the software.

Open Source

Open source software is software that is free for the public to use, study and change the software as they want, even charge a price for it it they want to sell it. It is like software that is in the public domain , free for any or to use.
