Assume that the OS is using a memory segmentation method, instructions are 1 word long, and each address in memory accesses only one word.

A segment table for a particular process is given below:

Segment Number	Size	Starting Address
0	3,000	13,000
1	4,000	7,000
2	1,000	20,000
3	500	6,000
4	10,000	30,000

Calculate a physical memory address for each of the following instructions. If the address cannot be calculated using the segment table, say why not.

segment #1, instruction #50

segment #2, instruction #900

segment #3, instruction #600

segment #5, instruction #800
