Consider the following segment table What are the physical a

Consider the following segment table: What are the physical addresses for the following virtual addresses? 4.44 1.22 Briefly compare segmentation to paging.

Solution

a) Physical address for 4,44:

2200+44 = 2244

Physical address for 1,22:

Illegal reference

b)      Paging and segmentation are different in the following ways:

1) A page is a contiguous range of memory addresses which is mapped to physical memory whereas a segment is an independent address space.

2) A has only one linear address space whereas a segment has many address spaces.

3) A page is a physical unit whereas a segment is a logical unit.
