A foreground task refers to a process or activity that is currently active and visible to the user on a computer or mobile device. This task requires the user's attention and interaction, such as typing a document, browsing the internet, or playing a game. Foreground tasks are prioritized by the operating system, ensuring they receive the necessary resources for smooth performance. In contrast, background tasks run behind the scenes, performing functions like updates or data syncing without direct user interaction. Understanding the difference between foreground and background tasks helps users manage their devices more effectively, optimizing performance and multitasking capabilities.
