Even though the OT plays a vital, community understanding of Intellectual Property Rights of software (IPR PL) is still relatively minimal. This increases with increased use of Free Software (PLB) Free Software and Open Source Software (PLST) Open Source Software (OSS). PLB is often mislabeled as PLST, even if in fact there are some fundamental differences between both approaches. Basically, PLB prefer the fundamentals of freedom, whereas PLST prefer the practicality of the use of the OT itself.

The concept of Open Code Software (Open Source Software) is essentially an open source code (source code) of software. This concept seemed weird at first because the source code of a software key. With known logic in the source code, then others should be able to make the same software functions. Open source is nothing more.

That is, should not be free. We could make the software that we open its source code, patented algorithm, and its copyright, and keep selling the software commercially Open source is one of the terms free software. Free software is definitely open source software, but open source software is not necessarily free software. Examples of free software are Linux. An example of open source software is FreeBSD.
