Background processes are tasks that run on a computer or device without direct user interaction. These processes handle various functions, such as updating software, managing system resources, or performing scheduled tasks. They allow the main applications to run smoothly by taking care of necessary operations in the background. Examples of background processes include antivirus software scanning for threats, system updates downloading new features, and cloud storage syncing files. While users may not see these processes, they are essential for maintaining system performance and security, ensuring that everything operates efficiently without interrupting the user's experience.
