No. Licences must comply with the open source definition defined by the Open Source Initiative (OSI). The only criteria is that they be OSI approved, but need not contain the exact same terms and conditions.
Not at all. Closed source is more difficult to service, maintain and modify. Open Source provides complete transparency. Open source software is neither good or bad but simply a set of license terms and conditions that dictate how the software needs to be licensed if it is modified and redistributed. One reason developers can modify it in the first place is that the underlying source code--rather than just an executable file--is distribted as one of these terms and conditions (depending on whose definition you use there are either 4 or 10 of these terms and conditions and there are all kinds of variations--dozens if not hundreds--of open source licenses).
Open Source Software.
Open-source software refers to software that that has licensing terms that allows modification and distribution.
Open source software is software that allows the source code to be used. Oftentimes, they are free to use. Open source software is copyrighted.
I prefer open source software.
Open source software allows anybody to revise and reformat the software to suit their individual needs. Open source software is usually developed together and publically.
no....because an open source software is distributed for free
The answer is in the question itself. Open-source software has it's source code available to everyone. Closed-source software does not.
Open Source Software Institute was created in 2000.
