To reload systems software into a computer so that it makes a new start.
rebootTo reload the operating system and start over. A reboot often solves many software problems in computers, smartphones, tablets, cable boxes and other electronics devices, because it resets the system.
Restart Vs. Shut Down/Start
If a Restart option in an electronic device is selected from the menu, the current applications are closed, and the operating system is reloaded. This is a "warm boot," which does not clear internal RAM memory. When Shut Down is chosen, and the unit is turned back on, this "cold boot" clears memory and reloads the OS, which is often more effective for solving problems than restarting. See cold boot, clean boot and boot.
