But in general, there are many types of software and their definitions. Here is types of software currently available: Proprietary software is software that is not free or semi-free and not open. Users are prohibited from or ask for permission or is restricted if use, distribute or modify it. Source code normally not available. Examples of proprietary software is a windows operating system. This type of software that most subjected to raids by the authorities.
Open source software
Pattern of Open Source was born because freedom works, without intervention to think and express what they want using knowledge and suitable products. Freedom becomes a major consideration when released into public. Other communities have the freedom to
earn, work on, revise again, to justify or even blame, but this freedom also
omes along with responsibility, not freely without reponsibility.
Open source software is often confused with free software, but there are some things that must be met when considered as open source software, ie free distributed without any royalty requirements, program must have the source code, the license must be modified and lowered, the integrity of the maker source code, the license does not discriminate against a person or group of people, there is no discrimination against the area development, copyright in a program must be able re-applied and distributed by anyone, a license not refer to the specifications of a product, no license limit the places where the software is distributed, and the license must contain a neutral technology.
Free Software
The definition of Free Software leads to freedom for run, copy, distribute, study, change and improve the software. There is four kinds of freedom for software users, namely:
1. The freedom to run the program for the purpose anything
2. The freedom to study how the program works, and adapt to user needs. Access to the source code is a precondition.
3. The freedom to redistribute copy of the software so you can help fellow users.
4. The freedom to improve the performance of the program, and can disseminate to the public so that all enjoy the benefits.
The term Open source software is used by several parties which means more or less the same as Free Software, but more to avoid the term Free / free to often mean free, while also to attract business users. The combination of Free Software and Open Source Software to form a more familiar term with Free Open Source Software. This is currently are encouraged to suppress piracy in Indonesia, one of which is IGOS (Indonesia, Go Open Source).earn, work on, revise again, to justify or even blame, but this freedom also
omes along with responsibility, not freely without reponsibility.

Semi-free software
Semi-free software is software that not free, but allow all parties to use, copy, distribute, and modify (including distribution of versions that have been modified) for nonprofit purposes. Examples of software This is the kind of PGP.
Copyleft
The software is copyleft free software that distribution terms do not allow for add additional restrictions, if it distributes and modify the software. But every copies of the software although it has been modified, is free software. Copyleft is a general term which when a program in-copyleft should use the provisions certain distribution. Copyleft guarantees that the device software is free to all users. So, kasarannya is software that is free, but limited in terms has been determined. An example is the GNU GPL.
Free software is non-Copyleft
Free software is a tool of non-copylefted software by the manufacturer allowed to be distributed and modified, and to add constraints Additional therein. If a program is free but not copylefted, then some copies or modified versions may be not free at all. A software company can compile the program, with or without modification, and distribute the executable file as a product a proprietary software. Examples of licenses without copyleft is BSD (Berkley Software Distribution) and MIT (Massachusetts Institute of Technology).
Freeware
The term refers more freeware packages program which permit redistribution but not modification (And the code is not available). Freeware distributed in binary form without any licensing fees. Freeware is often used in promotional programs as additional software on the sale of proprietary software and also to increase sales.
Shareware
Shareware is software that allows people to redistribute copies, but when the user continues to use it are asked to pay licensing fees. Shareware is not free software or semi-free. This is because most of the shareware, source code is not available, so do not can be modified at all. In addition it is not shareware allow users to copy and install it without pay a license fee. Usually the use of shareware initially free, but limited time use, or the concept of freeware but the items or limited function. If you want to fully functional, it is necessary to pay in advance. Games particular on the Internet many software types this.
Commercial software
Commercial software is software that developed by businesses to obtain benefit from its use. It could be developed from open source software that is then resold by the businesses after a modification. The point is a software developed to obtain financial gain.
Public domain software
Public domain software is software that without copyright. Some use the term public domains independently, which means free of charge or for free. But the public domain is a legal term which means not own the copyright. In other words, the software type is not bound by the law relating to rights copyright, so each party is entitled to do anything of this software, aka non-proprietary. Although not Orphaned, not that kind of software is safe.
