Keyword reference for segmentation

Question 120 (2013):

Submission reference: IN2998

When you're looking up some memory using segmentation, you find the physical address by using the segment number and the offset. Is this the physical address of the memory you want or is it the address of the start of the segment?

Answer 120:

The physical address of the memory you were after (assuming the mapping is valid and that memory exists). The start of the segment is the same thing but without the offset added/or'd in.
