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 demand paging in Unix?
In computer operating systems, demand paging is an application of virtual memory. In a system that uses demand paging, the operating system copies a disk page into physical memory only if an attempt is made to access it (i.e., if a page fault occurs). It follows that a process begins execution with none of its pages in physical memory, and many page faults will occur until most of a process's working set of pages is located in physical memory. This is an example of lazy loading techniques.
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.

What is the significance of optimal page replacement in the context of memory management systems?
Optimal page replacement is significant in memory management systems because it minimizes the number of page faults, which occur when a requested page is not in memory. By replacing the page that will not be used for the longest time, optimal page replacement can improve system performance by reducing the frequency of page faults and improving overall efficiency.
