英文回答：

Background Tasks.

Background tasks are processes or operations that run

asynchronously in the background of an application or

system. They are typically executed separately from the

main user interface (UI) thread, allowing the application

to continue responding to user input and other foreground

activities while the background task is running.

Background tasks can be used for a wide range of

purposes, including:

Data processing and analysis.

File downloads and uploads.

Network requests and communications.

System maintenance and updates.

Long-running calculations or simulations.

Background tasks are often implemented using threads or

separate processes. Threads are lightweight and share the

same memory space as the main application, while processes

are independent entities with their own memory space. The

choice of which approach to use depends on the specific

requirements of the background task, such as its resource

usage, isolation level, and need for inter-process

communication.

One of the key benefits of background tasks is that

they can improve the responsiveness and performance of an

application. By offloading time-consuming tasks to the

background, the main UI thread can remain responsive and

continue to handle user interactions smoothly. This is

particularly important for applications that need to handle

real-time events or provide a continuous user experience.
