Which Of The Following Is The First Step In The Boot Process?
The first step of the boot process is to provide power to the machine. Today, let us discuss the Boot process on a computer in detail. The understanding of the boot process gives various legal information. We use the boot tools in order to control the booting process. Let us understand this in detail, what happens when we boot a computer.
While we turn on the computer, the power supply will send the power to the motherboard of the computer. The motherboard plays an important while operating the computer. when we send power to the motherboard, it will activate the boot process.
The ROM is called the read-only memory, where it stores the power on instructions in it. We have a read-only memory chip, which is part of bios(basic input-output system). A series of tests will be performed on the post to check if the system working correctly or not.
The post instructions are nothing but a combination of audio and visual messages. The post instructions will checks each part of the CPU that displays it. It also checks the random access memory(RAM). Checking RAM is one of the basic steps to know whether it can communicate or not. It also checks the keyboard, mouse. It displays on the screen how to set up the bios program on the screen. We will have different keystrokes for each of the bios software vendors. Enter the keystroke of your system, it mostly is f2,f10 or it can be a delete key. It also stores the date, time, and booting order.
We can set the computer to boot it from the hard drive, CD, or can be from USB. We need to change the boot order to set the computer to boot through a CD or hard drive. Now, let us know the process of booting in detail.
Firstly, we switch on the power supply of the computer, the power will be sent to the motherboard of the computer. After this, we try to load the operating system of the computer into the main memory. The main memory is nothing put in the place where all the operations are getting executed. In order to perform any operation, first, it should load into the main memory.
After this, we try to keep all the applications of the computer in a ready state, to make them available for the users if needed. The first program that runs on the computer after we switch on the system is BIOS. We might also reboot the system if any new software is installed on the computer. There is a chance of reboot if the system gets slow.
We have two types of booting. They are warm booting and cold booting. When the system needs to restart even it is in a running state, this is called warm booting.
And cold booting can be defined as after we start the system and give the power supply and the next step to perform this is to load the bios. This is called cold booting.
