What is Booting?

When we start our computer then there is an operation which is performed automatically by
the computer which is also called a booting . In the booting, system checks all the hardware
and software those are installed or attached with the system and this also load all the files
those are needed for running a system.

These are two types of booting.
1. Warm Booting 2. Cold Booting

8 Warm Booting : Warm booting is the process of restarting a computer. It can be
initialised using the operating system. In Windows, the user can perform warm booting
by selecting the restart option from the start menu. Usually, warm booting is performed
frequently than cold booting because the users leave the computer in the sleep mode
when they do not work. Warm booting does not include power on self-test, but it
performs the rest of the boot sequence. It also loads any system files that were installed

before the computer was restarted.
8 Cold Booting : Cold booting is the process of starting up a computer that is switched off.
Usually, it is performed by pressing the power button on the computer. Cold booting
performs the “Power-on Self-Test” (POST). It is a series of system checks at the beginning
of the boot sequence. In other words, it checks whether all the requirements are met,

and the hardware is working correctly before starting the operating system.
When troubleshooting the computer, the user is asked to turn off the computer
completely. Then cold booting is performed. It clears all temporary data from the system
and eliminates the issues that can affect the functionality of the computer.
