Warm boot & Cold boot (Differences between Cold and Warm Booting)

A warm boot is a reboot with the computer power placed in the on position. A cold boot is a reboot with the computer power being off.


Cold Booting
A cold boot is a boot process in which the computer starts from a powerless state.
The start-up of a computer from a powered-down, or off, state.


Warm Booting
Refers to restarting a computer that is already turned on via the operating system. Restarting it returns the computer to its initial state. A warm boot is sometimes necessary when a program encounters an error from which it cannot recover. On PCs, you can perform a warm boot by pressing the Control, Alt, and Delete keys simultaneously. On Macs, you can perform a warm boot by pressing the Restart button.
