Software that is limited to a spesific computer model
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.
Linux is an operating system kernel. By itself, it can do very little. It needs to be combined with an interface and applications in order to be useful. When you take the kernel and add the parts to create a working system, you create what is called a "Linux distrbution", or "distro." Fedora is an example of a Linux distro. In summary, Linux is a kernel, and Fedora is a full operating system.
An open system is an operating system that is entirely free to use, copy or pass on to others. Linux Mint and Ubuntu are just two examples of many that are freely available for downloading from the internet.A proprietary system is an operating system that has to be paid for, has to be registered, and is never yours to own, copy or pass onto others. Microsoft's Windows is an example of proprietary systems software.
Linux wine allows the user to run Windows software when they are using a Linux operating system. One would like to do this if they like how Windows software works rather than the Linux equivalent, for example some people like Microsoft Office products.
Most applications are available at your distribution's repositories, however depending on the kind of distribution, you may have the option to use user-created repositories that allow you to use applications or dependencies that offer features the official packages do not have, or that the official packages are not offered due to legal issues (some distributions have a strict policy against including non-free/proprietary software in their repositories).
Proprietary database are the databases that work only on particular software not on any other. For example cisco proprietary routers can only be used with cisco devices.
