Windows Subsystem for Linux (WSL) is a compatibility layer for running Linux binary executables natively on Windows 10 and Windows 11. It allows users to run a Linux environment directly on Windows without the need for a virtual machine or dual-boot setup.

Key features of WSL include:

  1. Integration with Windows: Users can access files from both Windows and the Linux environment seamlessly.
  2. Multiple Distributions: WSL supports various Linux distributions, such as Ubuntu, Debian, and Fedora, which can be installed from the Microsoft Store.
  3. Command-Line Tools: Users can run Linux command-line tools and applications directly in Windows, making it easier for developers to work in a familiar environment.
  4. Performance: WSL provides near-native performance for Linux applications, making it suitable for development and testing.
