Application dependencies are the external components, libraries, and frameworks that a software application requires in order to function correctly. These dependencies may include things like operating system libraries, third-party libraries, and other software applications that the application relies on in order to run.
For example, if an application is written in Python, it might have a dependency on the Python runtime environment and specific Python libraries. If the application is a web application, it might have dependencies on web servers, databases, and other web-based technologies.
