What is the fundamental difference between a 'cold boot' and a 'warm boot' of a computer system?

Correct option is B

The correct answer is (B) A cold boot restarts the operating system from a powered-off state, while a warm boot restarts it from a running state.

Explanation:

• A cold boot (also known as a hard boot) occurs when you turn on the computer after it has been powered off. It involves starting the system from a completely powered-off state, and the computer loads the operating system from scratch.
• A warm boot (also known as a soft boot) occurs when the system is restarted without turning off the power. This is typically done by restarting the computer from an already running state, either through the operating system's restart option or by pressing the restart button.

Information Booster:

• Cold boot: Initiates the system from a completely powered-off state, requiring the system to load the operating system, BIOS/UEFI, and other startup processes.
• Warm boot: Restarts the system from a state where the operating system is already running, often quicker as it doesn’t require loading BIOS/UEFI or hardware initialization.
