Proprietary source software is software which has a copyright on it and can not be legally modified without encroaching on the author's rights. Most software produced by organizations or individiduals for sale fall into this category, i.e. you can not legally modify the code.
Software source code that has no legal text is generally public domain, which means that you can modify it and use it as you please. You might need to check if someone deleted the legal text specifying ownership if you received the source code from someone else; in this case the legal text still applies even if you did not receive it.
Most software source code will have a legal text that might specify it to be using the GNU public license (or other similar license) in which case you must adhere to the modification rules specified by the license. In the case of the GNU license, any modification you make also becomes public domain and modifiable and usable by other people.
I prefer open source software.
Access to the source code of proprietary software is typically restricted to the developers and authorized personnel of the company that owns the software.
No. It is open source software.
no....because an open source software is distributed for free
Linux is open source, not shareware or proprietary. There are commercial Linux distributions.
Linux is an open source software that has not had a detrimental affect on the marketing of proprietary software. Linux is computer operating system assembled under the model of free and open source software development and distribution.
Yes it is. It is owned by Microsoft and they do not give access to the source code for the program, unlike open source software programs.
Freeware is computer software that is distributed without charge. Open source is computer software the author of which claims no copyright. There are several ways "open source" is defined, the most popular being GNU. However! Freeware can be copyrighted, and open source can be sold for money.
Software that is both open source and proprietary typically falls under dual licensing models. Examples include MySQL, which offers an open-source community edition alongside a proprietary version with additional features, and MongoDB, which provides an open-source version with a commercial license for its advanced offerings. Another example is the Qt framework, which is available under both open-source and commercial licenses, allowing developers to choose based on their project needs. This model allows companies to leverage the benefits of open source while also monetizing their software through proprietary licenses.
free to distribute/ update as you require. but people only use it if good, not junk open source ones
Software that is limited to a spesific computer model
Software that has no terms and conditions attached to it and the source code is available to everyone that can download it. It is very rare to find software like this and normally there is no company ownership.
