Q7. Assume that logical address is mapped to physical memory by using a segmentation scheme. The details of the segmentation scheme are as follows. (Marks: 20) - s: a segment number - d: an offset into that segment. - Trap can be generated if there is addressing error. - The segment table is shown in the below figure seament table physical memory a- Find the corresponding physical addresses of the below logical addresses by using the segmentation scheme. b- Notify whether the corresponding physical addresses is valid or not. (1) Logical address: s=0,d=50 (2) Logical address: s=1,d=550 (3) Logical address: s=2,d=550 (4) Logical address: s=3,d=50
