3. (10 points) On a system using segmentation to manage main memory, the segment table for the currently running process is listed below: Segment # V Base 0 1 1020 1 2 3 4 0 74 1 19 1 4810 1 3220 a. Read from virtual address 2, 16 b. Write to virtual address 1, 10 c. Write to virtual address 3, 5000 Bounds 500 12 78 5730 2160 d. Read from virtual address 0, 600 e. Read from virtual address 4, 2000 Access read For each of the given memory accesses, determine if (i) the access is valid, and (ii) what the physical address is for each valid access. If the access is invalid, briefly explain why. read/write read/write read read/exec
