Question

If the segment descriptor bit, S=0, then the descriptor is

(a) data segment descriptor

(b) code segment descriptor

(c) system descriptor

(d) all of the mentioned

I had been asked this question in an online interview.

I'd like to ask this question from Segmentation in chapter 32-bit Processors-80386, 80387 and 80486 of Microprocessor

Answer 1

The correct choice is (c) system descriptor

To elaborate: If S=0, then system descriptor. If S=1, then code or data segment descriptor.
