3 Questions
Explain demand paging and provide a neat sketch to illustrate its concept.
Demand paging is a technique used in virtual memory systems where pages are only brought into memory when they are demanded by the running program. This helps to reduce the amount of physical memory needed and allows for efficient memory management. A neat sketch should illustrate the concept of bringing pages into memory on demand.
What are the benefits of demand paging in virtual memory systems?
Demand paging allows for efficient memory management by bringing pages into memory only when they are needed, reducing the amount of physical memory needed and allowing for larger virtual address spaces. It also helps to minimize the initial loading time of the program and allows for better overall system performance.
How does demand paging differ from other memory management techniques, such as pre-paging?
Demand paging only brings pages into memory when they are demanded by the running program, while pre-paging brings in additional pages before they are actually needed. Demand paging helps to minimize unnecessary memory usage, while pre-paging aims to reduce the likelihood of page faults by bringing in anticipated pages ahead of time.
