Question
What is virtual memory?
Answer
Virtual memory is a memory management capability that offers an abstraction of storage resources, allowing larger applications to run on systems with limited physical RAM.
Question
What does paging in virtual memory management involve?
Answer
Paging is a memory management scheme that eliminates contiguous allocation, using fixed-size pages and frames, thereby reducing fragmentation.
Question
What was the significance of the Multics operating system?
Answer
Multics was a pioneering operating system that expanded on the ideas of CTSS, incorporating paging and segmentation for efficient memory management.
