For example, the programme eliminates many of the performance and memory penalties that are associated with some operating system emulators. Wine is different and makes real-time API calls into POSIX which means that it is much more flexible. Although many emulators exist, they tend to simulate internal Windows logic like a virtual machine. Windows FunctionalityĬapable of running on several POSIX-compliant operating systems, Wine makes using Windows applications without a Windows operating system simple. Because it translates Windows API as it goes, it does not function like a traditional emulator at all. Wine is a free compatibility layer which operates as a virtual Windows operating system on devices running other ones, such as Linux, MacOS and BSD.
