Question

Write down the advantages of virtual memory?

Answer 1

1. A higher degree of multiprogramming.
2. Allocating memory is easy and cheap
3. Eliminates external fragmentation
4. Data (page frames) can be scattered all over the PM
5. Pages are mapped appropriately anyway
6. Large programs can be written, as the virtual space available is huge compared to physical memory.
7. Less I/O required leads to faster and easy swapping of processes.
8. More physical memory is available, as programs are stored on virtual memory, so they occupy very less space on actual physical memory.
9. More efficient swapping
