Memory Management is the crucial part of the concurrent systems.Various methods are used to utilize memory efficiently.Memory paging is the one from them .
Memory Paging:pagingis one of the memory-management schemes by which a computer can store and retrieve data from secondary storage for use in main memory. In the paging memory-management scheme, the operating system retrieves data from secondary storage in same-size blocks called pages. The main advantage of paging over memory segmentation is that it allows the physical address space of a process to be noncontiguous. Before the time paging was used, systems had to fit whole programs into storage contiguously, which caused various storage andfragmentation problems.[1]
Paging is an important part of virtual memory implementation in most contemporary general-purpose operating systems, allowing them to use disk storage for data that does not fit into physical random-access memory (RAM).

What is memory management scheme which support the user's view of memory?
paging
What is contiguous allocation?
Paging is a memory management scheme that permits the physical- address space of process to be noncontiguous.
WHAT IS SINGLE USER CONTIGUOS SCHEME?
Single user contiguous scheme is a memory allocation technique where a single block of contiguous memory is allocated to a process. This means that the entire memory space needed by a process must be available in a single block without any breaks or fragmentation. It simplifies memory management but can lead to wastage of memory due to fragmentation.
When was State Management Scheme created?
State Management Scheme was created in 1916.
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.
Functions of the memory manager?
Memory management functions handle the allocation and deallocationof dynamic Memory. These functions form an abstraction layer above the standard C memory management functionsmalloc, free, and realloc.This block of functions can be replaced by the user with custom code to implement a different memory management scheme. For example, an embedded system application might want to use a fixed-sized static block from which to allocate.
What is the purpose of swapping?
Swapping was an older form of memory management. It was moving from/to secondary storage a whole program at a time, in a scheme known as roll-in/roll-out. Now swapping is a fairly close synonym of paging.
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 color scheme compltary persistence of memory?
pink,red,blue
What are the main component of operating system?
Paging is a memory management technique the scheme removes requirement of contagions allocation of physical memory. In paged system each process id divided into set of pages frames of the same size. The following figure shows an example of 3 process which have been loaded into contagious pages in the memory.

The name of Apple's proprietary digital rights management scheme?
Apple's Digital Rights Management (DRM) software is called FairPlay.
