To "uninstall" means to remove a software application or program from a computer or device. This process typically involves using the operating system's built-in tools to delete the program files and any associated data. Uninstalling helps free up storage space and can improve device performance. When you uninstall a program, it is often done through the Control Panel on Windows or the Applications folder on macOS. Users can also use specific uninstaller software designed to remove programs completely. After uninstallation, the program will no longer be accessible on the device.
