Compare between the one and two-dimensional memory organizations in terms of the memory structure, advantages, and disadvantages. Which approach would better support the needs of modern operating environment? Why? Please
Consider the following segment table in a two dimensional memory organization:
1- Draw the map of the address space above (i.e. memory map) where X axis represents the segment number and Y axis is the addresses within a segment.
2- Evaluate the physical address for each of the following logical addresses; locate each address on the memory map.
a- (0, 867) b- (1, 3950) c- (2, 2340) d- (3, 7120) e- (4, 1625)
