Answer 1

*Answer:Tracks which physical block contains only valid pages.(option c)

Beacause of following reason

Flash layer translation only tracks the physical block which has the valid pages

And rest of the options are wrong because

It does not translate the user data to the format that can be written on the nvm

And does not tracks the invalid pages

And also doesn't traacks the consecutive invalid pages as it tracks only valid pages.

*Answer:swap system may used to store file system(option c)

​​​​​​This is the false statement regarding the swap space use

It doesn't store the file system at all

So it is the false statement

It does

Storing the pages that has pushed out of main memory

And also holds the process image

And it can be dedicated swap partition,a swap file ,or combination of both swap file and partition.

Answer:is stored in rom to ensure to avoid any infection from viruses.(option d)

This is the correct statement that suits

As full boot strap program is stored in Rom to ensure to avoid the infections from the virus

*It is first code which has to executed ,when computer has started.

And rest of the options are wrong because

A full boot strap program is not the virus,that is to infect.

And it is not an operating system because it is the code .

And it does not run after Operating system has loaded into memory,as we know it runs initially.
