Master Boot Code: The master boot record is the small bit of computer code that the BIOS loads and executes to start the boot process. This code, when fully executed, transfers control to the boot program stored on the boot (active) partition to load the operating system.
Which of the following takes place first in boot process?
The first step of any boot process is applying power to the machine. When the user turns a computer on, a series of events begins that ends when the operating system gets control from the boot process and the user is free to work.
What are the steps in the boot process?
Although it is possible to break down the boot-up process using a highly detailed analytical methodology, many computer professionals consider the boot-up process to consist of five significant steps: power on, POST, load BIOS, operating system load, and transfer of control to the OS.
During which step of the boot process does the computer or device load the operating system files into RAM?
The BIOS then starts the boot sequence. It looks for the operating system stored on your hard drive and loads it into the RAM. The BIOS then transfers control to the operating system, and with that, your computer has now completed the startup sequence.
During which step of the boot process does the computer or device load the operating system files into RAM quizlet?
The boot strap loader looks for the operating system on the hard drive and begins loading the operating system that is found, like Windows or macOS. The OS determines memory (RAM) available and loads hardware device drivers to control keyboard, mouse, etc.

What are the four steps involved in the boot process?
1. Boot Process Overview
- BIOS. The BIOS (stands for “Basic Input/Output System”) initializes the hardware and makes sure with a Power-on self test (POST) that all the hardware is good to go. …
- Bootloader. The bootloader loads the kernel into memory and then starts the kernel with a set of kernel parameters. …
- Kernel. …
- Init.
What is the most important role of BIOS?
BIOS uses Flash memory, a type of ROM. The BIOS software has a number of different roles, but its most important role is to load the operating system. When you turn on your computer and the microprocessor tries to execute its first instruction, it has to get that instruction from somewhere.
What is booting process and its types?
Booting is of two types :1. Cold booting: When the computer is started after having been switched off. 2. Warm booting: When the operating system alone is restarted after a system crash or freeze.
What does BIOS provide for the computer?
BIOS (basic input/output system) is the program a computer’s microprocessor uses to start the computer system after it is powered on. It also manages data flow between the computer’s operating system (OS) and attached devices, such as the hard disk, video adapter, keyboard, mouse and printer.
Which three hardware components does the computer need before it can load the BIOS?
For a successful boot 3 things need to work properly: BIOS (Basic Input Output System), the operating system and the hardware components.
