In certain situations the page tables could become large enough that by paging the page
tables, one could simplify the memory allocation problem (by ensuring that everything
is allocated as fixed-size pages as opposed to variable-sized chunks) and also enable the
swapping of portions of page table that are not currently used.

Paging the page table allows for efficient memory management by only loading the necessary portions of the page table into memory when needed, reducing memory overhead. This helps optimize memory usage and allows for larger address spaces to be managed effectively. It also enables the operating system to easily handle memory protection and sharing among processes.

What is the purpose of paging the page tables?
The purpose of paging the page tables is to allow a computer's operating system to efficiently manage memory by dividing it into smaller, fixed-sized units called pages. Paging enables the computer to allocate memory more flexibly and efficiently than using a contiguous block of memory for every process. Page tables are used to map virtual memory addresses to physical memory addresses. When a program accesses a memory location, the virtual memory address is looked up in the page table to determine its corresponding physical memory address. Paging the page tables allows the computer to keep only the necessary parts of the page table in physical memory at any given time. This is important because page tables can be quite large, and keeping the entire table in physical memory would be wasteful of resources. When a process needs to access a memory location that is not in physical memory, the page table entry for that location indicates that a page fault has occurred. The operating system can then load the necessary page into physical memory from disk, updating the page table accordingly. Overall, paging the page tables allows the operating system to make efficient use of memory by allocating it as needed and only keeping necessary portions of the page table in physical memory.
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 excessive paging?
Excessive paging is when you page someone over and over again.

What is paging and segmentation in an operating system?
Paging refers to the division of address spaces into fixed size units and the logical addresses are in the form of tuples. On the other hand, segmentation is the dividing of address spaces into a defined number of segments.
What is the opposite of paging device?
The opposite of paging device is no paging device. Either someone can page you or they can't. Prior to pagers and cell phones, there were just landline phones.
Can combination of paging and segmentation result in better performance?
* Combine Paging and Segmentation ** Structure *** Segments correspond to logical units: code, data, stack. Segments vary in size and are often large. *** Each segment contains one or more (fixed-size) pages. ** Two levels of mapping to make tables manageable (2 look-ups!) *** Page table for each segment. * Segments Pages Advantages ** Advantages of Segments *** Supports sparse address spaces. If segment is not used, no need for page table. Decreases memory required for page tables. ** Advantages of Paging*** Eliminate external fragmentation. ** Advantages of Both. Increases flexibility of sharing. Share at two levels: Page or segment (entire page table). * Segments + Pages Disadvantages ** Internal fragmentation increases. Last page of every segment in every process . ** Increases overhead of accessing memory *** 1 or 2 overhead references for every real reference. ** Large page tables *** Two potential solutions: Page the user page tables (multilevel page table), Inverted page table.
What is design issue of paging?
The design issue of paging is written as the Design Issues for Paging Systems. The Design Issues for Paging Systems helps sort out design issues in the start up of paging systems which require pages being loaded as needed, pages opened on demand, and programs being ran until there is a page fault.
