If virtualization is concerned, then answer would be choice d. Since its
not necessary to load complete process in memory.

Q1. If we have infinite memory, then do we still be needing paging?
Q2. Given only 8bits registers, you have to find average of 4 bit registers
values without using any operation involving 16 bit calculations.

I think the answer to Q1 may Yes.
Cause the virtual memory of program is limited, they need logically
contiguous memory, and have limit from OS and processor(32-bit, or
64-bit) yet.
I have no idea about Q2.

I have a doubt when each process has it's own separate page table then why
is there s system wide page table required ? Also if Page table is such
that it maps virtual address to a physical address then I think two process
may map to same physical address because all process have same virtual

You will get the basics of processor mode of execution
and rings of execution
Hope I got the question !

What happens when a thread calls exec ?? What happens to the other threads
of the same process ??

I think the answer would be the thread calling execute will have to wait for
the executed command to exit and then it will proceed.
As for other threads, they shouldn't be affected.
Please do correct me if it is wrong.

@Dipankar: But all the threads of a process share code and data section. So,
how is it possible that they are not affected ???

To elaborate more. New process image will not have the existing threads and
user defined data declared in current process will be wiped out. Parent can
do is to wait for the child status by calling wait().
for example
main()
{
pid = fork();
if (child) {
exec(ls); ///
The *exec* family of functions shall replace the current process image with
a new process image. It does not matter how many threads you have whole
process gets replaced with new one.
