A "System Reset" refers to the process of restoring a device, such as a computer or smartphone, to its original factory settings. This action removes all personal data, applications, and settings, effectively giving the device a fresh start. It can help resolve performance issues, remove malware, or prepare the device for a new user. During a system reset, users typically have the option to back up their data before proceeding. This ensures that important files and information are not lost. After the reset, the device will function as if it were new, requiring reinstallation of applications and reconfiguration of settings.
