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.
What is pagging?
Paging is a system of locating the guest. If the guest is not in his allotted room but some where inside the hotel premises, paging is done to locate him the message.
What is the predominant reason for slight pauses in an applicatin when retrieving information from the paging file?
My best guess would be that, because the paging file is stored on the hard drive and considering that the hard drive is the slowest medium to retrieve infromation from, that it is caused by the computer looking for the correct information from a slower source.
Why would you want to move the paging file off of the boot partition?
Space. Speed - if the boot drive is slow and you have an alternate drive that is faster (don't want to reload windows) - a faster paging file will increase speed of Windows when you have a lot of applications running.
Why are segmentation and paging sometimes combined into one scheme?
Segments can be of different lengths, so it is harder to find a place for a segment in memory than a page. With segmented virtual memory, we get the benefits of virtual memory but we still have to do dynamic storage allocation of physical memory. In order to avoid this, it is possible to combine segmentation andpaging into a two-level virtual memory system. Each segment descriptor points to page table for that segment.This give some of the advantages of paging (easy placement) with some of the advantages of segments (logical division of the program). ok hope wil b helfill
The process of optimizing RAM storage by borrowing hard drive space called?
It's called Virtual Memory. Not paging!
The technique of swapping items between memory and storage?
It is paging.
Explain how virtual memory system using demand paging?
Demand paging is a process which involves the copying and relocation of data from a secondary storage system to random access memory (RAM), a main memory storage system. Demand paging copies and relocates data to facilitate the fastest access to that data. Once the data is relocated, demand paging sends a command to the operating system to inform it that the data file or files are now ready to be loaded. Demand paging is performed on demand, or after a command has been sent to retrieve specific data.
Explain in detail page memory management scheme?
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 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...
Why paging is needed?
Paging is a way for the operating system to load data from a storage device onto RAM. When there is insufficient amount of space in RAM and if a page file is enabled, it will swap data between RAM and the swap file (typically on a storage device).
Why paging is used?
Paging is solution to external fragmentation problem whichis to permit the logical address space of a process to benoncontiguous, thus allowing a process to be allocatingphysical memory wherever the latter is available.

Why operating system requires second storage support for its operation?
its a type of memory management technique in which the full utilization of main or physical memory is being done and the process which are idle can be placed in second storage or logical memory and in the time of use it can be placed in main memory from paging .
What is contiguous allocation?
Paging is a memory management scheme that permits the physical- address space of process to be noncontiguous.
When did Paging You end?
Paging You ended in 1946.
What is the purpose of auxiliary storage device in the computer and the function?
Auxiliary storage devices are used to provide additional, portable storage, as opposed to hard drives which are fixed inside the computer and serve as primary storage devices. ------------------------------------------------------------------------------------------------------------------ Auxiliary storage is a term used in mainframe computing and refers to the medium on which paging datasets reside.
