A Background Task is a process that runs behind the scenes in a computer or mobile device, allowing users to continue working on other tasks without interruption. These tasks can include downloading files, syncing data, or running updates, ensuring that the main application remains responsive and efficient. In many operating systems, such as Windows or Android, background tasks are managed by the system to optimize performance and battery life. Users can often see the status of these tasks in a notification area or task manager, providing transparency about what is happening without requiring direct user interaction.
