The term "Invoke Application" refers to the process of starting or launching a software program on a computer or device. This action can be performed through various methods, such as clicking an icon, using a command line, or selecting an option from a menu. Once invoked, the application becomes active and ready for user interaction. In many operating systems, such as Windows or macOS, users can invoke applications easily by navigating to their respective folders or using search functions. Additionally, mobile devices allow users to invoke applications by tapping on their icons on the home screen, making access quick and convenient.
