A "System Reboot" refers to the process of restarting a computer or electronic device to refresh its operating system and clear temporary data. This action can help resolve issues such as slow performance, software glitches, or unresponsive applications. Rebooting can be performed through various methods, including using the power button or selecting the restart option in the operating system's menu. During a reboot, the system shuts down and then starts up again, reloading all necessary software and drivers. This process can also apply to other devices, such as smartphones and tablets, ensuring they operate smoothly. Regular reboots can enhance overall system performance and stability.
