In computing, rebooting is the process by which a running computer system is restarted, either intentionally or unintentionally. Reboots can be either cold, in which the power to the system is physically turned off and back on again causing an initial boot of the machine, or warm in which the system restarts without the need to interrupt the power. The term restart is used to refer to a reboot when the operating system closes all programs and finalizes all pending input and output operations before initiating a soft reboot.
