What are the differences between simple paging and virtual memory paging?
In case of simple paging all pages should be in main memory to run a process..while in case of virtual memory paging pages can be loaded as needed by the processor i.e. called demand paging...
The technique of swapping items between memory and storage?
It is paging.
In paging how the virtual memory can be implemented?
its depends on number of processes in memory.
What is memory management scheme which support the user's view of memory?
paging
What is a memory characteristic where an application can request a specific item from memory?
Demand Paging
Is the condition of excessive paging referred to as thrashing when virtual memory is in use?
Nope, swapping and paging are essentially synonymous. Excessive paging is known as thrashing.
What is paging?
Paging is a memory management scheme, in which data is fetched from the disk to memory in the form of equal size blocks called pages.paging is a method for allowing the non-contiguous allocation of memory space to processes when nedded.
What is difference between demand paging n pure demand paging?
In demand paging, a page is not loaded into main memory until it is needed. In pure demand paging, even a single page is not loaded into memory initially. Hence pure demand paging causes a page fault. Page fault, the situation in which the page is not available whenever a processor needs to execute it.
WHAT IS TEMPORARY MEMORY CALLED?
Do you mean RAM? Or the paging file?
Why are segmentiation and paging sometimes combined into one scheme?
Segmentation and paging are combined in a scheme called Segmented Paging to leverage the benefits of both techniques. This allows for efficient management of memory by dividing it into segments based on logical partitions and further dividing those segments into pages for optimized memory utilization and protection. Segmenting helps in managing variable-sized data structures, while paging streamlines memory allocation and reduces fragmentation. By combining these two strategies, Segmented Paging enhances memory management and provides more flexibility in handling memory access and protection.
What is the minimum size of the paging file required to allow a memory dump in the event of a stop error?
That depends on how much memory is being used by the operating system, the apps and their data. In general a paging file is 2 to 3 times physical memory so, 4x the physical memory (paging file of 3x physical memory + physical memory) will guarantee enough room for all data IF the paging file is set to 3x physical memory. There would be more needed for the devices attached to the processor, but there will be holes in memory and these holes most often more than make up for the memory of attached devices.
When virtual memory is in use excessive paging is referred to as?
FALSE
