Techopedia explains Reboot
Reboot is a standard feature found in most operating systems. It may be performed for a number of reasons, such as after installation of a new program, to reload a slow performing computer and/or after a system freeze. To reboot, users can press CTRL+ALT+DEL together in most Windows operating systems or select the restart option from the start menu. Generally, a system rebooted on a running system takes less time than a system that is started from shutdown or closed mode.
