Discuss the similarities and differences between paging and segmentation.
What will be an ideal response?
Both are popular schemes for implementing virtual memory. Both allow virtual
address spaces to be divided into separate entities (pages or segments). Both are forms of
noncontiguous memory allocation. Paging deals with physical entities, while segmentation
deals more with logical entities. Paging trivializes the memory placement decision, while segmentation
involves complex memory placement like that in variable-partition multiprogramming.
Segmentation is more natural for sharing access control.
