What is the primary function of the Executor in the system?

The primary function of the Executor in the system is to handle asynchronous tasks. Executors are an essential component of concurrent programming, designed to manage the execution of tasks, often in a multi-threaded environment. They provide a high-level abstraction for running tasks in the background, allowing for better resource management and improved application performance, particularly when dealing with operations that can proceed independently of the main application flow.

By using an Executor, developers can easily submit tasks without having to manage the threads manually, which simplifies code structure and enhances scalability. This is especially useful in scenarios where tasks may take varying amounts of time to complete or when it is necessary to manage a pool of threads while executing multiple tasks concurrently.

The other options, while relevant in different contexts, do not pertain to the primary role of an Executor. Managing memory resources and storing large data files are responsibilities typically handled by different components or layers within a system architecture. Supporting user interface operations often falls under the domain of frameworks or libraries specifically designed for rendering and handling user interactions. Thus, the focus within the context of an Executor is specifically on the handling of asynchronous tasks, making that choice the most accurate.
