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...
One advantage of paging is that it allows for better memory management by breaking up physical memory into smaller, equal-sized chunks called pages. This helps in reducing external fragmentation and allows for more efficient use of available memory resources. Additionally, paging simplifies the process of loading and unloading programs into memory, as pages can be swapped in and out independently.
Paging is a memory management scheme in which physical memory is divided into fixed-size blocks called pages, and logical memory is divided into blocks of the same size called frames. The operating system uses a page table to map logical addresses to physical addresses during memory access. When a process requests data that is not in physical memory, a page fault occurs, leading to the system retrieving the required page from secondary storage into physical memory.
its depends on number of processes in memory.
FALSE
Nope, swapping and paging are essentially synonymous. Excessive paging is known as thrashing.
C:\pagefile.dat
It is paging.
C:\pagefile.dat
C:/pagefile.sys
Segmented page allocation is a type of memory management that uses base and bound registers to determine memory faults, similar to dynamic page allocation. More importantly it is different to dynamic page allocation since the entire process doesn't have to be in memory, similar to using virtual memory paging where the program is broken into pieces. Unlike virtual memory paging, the maximum virtual memory size is limited to the size of physical memory.
you're using virtual memory/a paging file
Virtual Memory-: Virtual Mem is also known as Swap memory. Swap memory:- Swap mem is the type of memory which allocates by the harddisk in the form of extra RAM for better functioning of the application in the case if you are facing a lack of RAM in order to run that software
It can as much as you want, you should just have enough space on your hard drive in order to save the paging file (virtual memory file).
False. It is called Thrashing.
