Detailed explanation-1: -A method where the computer is powered off first or is given a command that causes it to restart. A standard computer will run a short software during the cold boot procedure. A second program is launched at this point, the one responsible for loading the operating system.
Detailed explanation-2: -What Is a Cold Boot? A cold boot, also known as a cold reboot, cold start, or hard boot, starts a computer system from a completely powered-off state, meaning the computer’s power has been turned off completely and back on again.
Detailed explanation-3: -A cold boot removes power and clears memory (RAM) of all internal data and counters that keep track of operations, which are created by the OS and applications when they run. Erratic program behavior is often cured with a cold boot, also known as a “hard boot."
Detailed explanation-4: -Cold booting is the mechanism of starting a system after it has been turned off. Generally, it is accomplished by pushing the computer’s power button. The “Power on Self-Test” (POST) is performed via cold booting. It is a set of system checks performed at the start of the boot procedure.
