No code emulation or virtualization occurs when running a Windows application under Wine. There is some confusion caused by an early FAQ using Windows Emulator and other invalid sources that appear after the Wine Project name being set. The selection of 'Wine is Not an Emulator' as the name of the Wine Project was the result of a naming discussion in August 1993 and credited to David Niemi. Wine is predominantly written using black-box testing reverse-engineering, to avoid copyright issues. Wine provides its compatibility layer for Windows runtime system (also called runtime environment) which translates Windows API calls into POSIX API calls, recreating the directory structure of Windows, and providing alternative implementations of Windows system libraries, system services through wineserver and various other components (such as Internet Explorer, the Windows Registry Editor, and msiexec ). Wine also provides a software library, named Winelib, against which developers can compile Windows applications to help port them to Unix-like systems. Wine (formely a recursive backronym for Wine Is Not an Emulator, now just 'Wine') is a free and open-source compatibility layer that aims to allow application software and computer games developed for Microsoft Windows to run on Unix-like operating systems.

ReactOS (for Windows app and driver compatibility).

We can install wine for deb based distributions like Ubuntu, Mint, and Kali with the following apt command.

Wine can be installed in different ways like distro repositories or downloading the package from wine site.

Wine converts Windows API calls into POSIX calls and prevents disadvantages of other emulations methods.

It is mainly called a compatibility layer which will match application system calls with the underlying operating system calls. Wine is designed to run Windows applications on POSIX compatible operating system Linux, MacOS, and BSD. Wine is known as an emulator but it describes itself as Wine Is Not an Emulator. Wine is a tool used to run Windows operating system applications like Office, Game, Desktop, Design, etc in a Linux distribution like Ubuntu, Debian, Mint, Kali, Fedora, CentOS, etc. Linux is a very flexible operating system that provides different options for other operating system applications users.
