Concept:Restarting a computer that is already switched on is known as warm booting.
Explanation:Cold booting means starting a computer from a completely powered-off state.
In cold booting, the power supply must be turned on and the operating system is loaded afresh.
Warm booting is the process of restarting a computer without switching off the power supply.
It is usually done by selecting the Restart option from the operating system menu.
During warm booting, the system shuts down software processes and then starts up again immediately.
This process is faster than cold booting because the computer does not have to be powered on from zero.
The given question specifically asks for the process of restarting a computer.
Therefore, the correct term is warm booting.
Answer:B. Warm booting
