___________ booting is done by turning on the computer at first instance.

"Cold" booting is done by turning on the computer at first instance. Booting is the process of starting a computer, and it can be done in two ways: cold booting and warm booting. A cold boot occurs when a computer is turned on after being completely shut down. This is the first time the computer is starting up and all components are starting from a completely powered-off state. This type of booting is often necessary when there are problems with the operating system or software and a restart does not resolve the issue. A warm boot, on the other hand, occurs when a computer is restarted without first being shut down. This type of booting is usually faster than a cold boot because some components remain powered on and do not need to be restarted from a completely powered-off state. The options "hot," "spicy," and "cool" are not relevant to booting a computer.
