      ii. kernel is loaded onto the memory

      iii. firmware ROM loads boot block

a. (ii, iii, i)

b. (iii, i, ii)

c. (i, ii, iii)

d. none of the above​

Answer 1

The booting process is very important for one's computer whenever one wants to perform it.

The boot loaders are used to find out for any information from the interface where all information is stored.

Just after the power button goes, the boot loader starts to pull all memory and every time we wish to switch on our computer again, the power on self test starts to work.

The second option is someway a part of the first option as when we boot a system, it starts to function the kernel memory and the kernel fully boots itself before anything is left.

Again third part follows after this just before the system needs to be rebooted. It ensures that no damage is caused to the computer.

Hence the correct order is option C i.e. i, ii, iii.

Answer 2

Answer:

(b) iii, i, ii  is the correct order of events.

Explanation:

BIOS consists of Bootloader firmware. In this process it will check for all input and output devices, memory, detect other devices. According to the options provided here, firmware rom is the first process to load and then it loads the boot block.

Bootstrap is the process will initialize the operating system. Kernel is the central and most important part of OS. It manages CPU time. It is the lowest level of operating system.
