Paging is a technique with the help of which we can divide the memory into pages which help us to easly access the files and it also decreases the Execution time (Saves SYSTEM time). It also creates a mirage of Memory.

What is a paging algorithm?
"Paging" is when the operating system writes contents of RAM memory to disk, to free space for other uses.A paging algorithm specifies which RAM content to page (write to disk) when it needs more space.See related link.
What is segmentation in computer memory?
memory segmentation is the process of dividing the computer memory into different overlapping segments.
What dries faster cotton or nylon?
cotton dries faster than nylon because of cotton is a material which absorb water faster than nylon that is why cotton dries faster than nylon
What tarvles faster than a jet plane?
a rocket travles faster than a jet plane
How much faster is the cotton gin than a human?
20 time faster than an individual human
How Intel Pentium supports segmentation and paging?
The Intel Pentium supports pure segmentation and segmentation with paging. The processor creates logical addresses, which are mapped to physical addresses by the segmentation unit. Those addresses may point to physical addresses within memory or paged swap space.
Advantages of segmentation over paging?
Advantages of segmentation over paging: Speed. Reloading segment registers to change address spaces is much faster than switching page tables. Segment descriptor tables consume less memory than page tables. x86 page table entries do not have an 'Executable' bit. With segmentation, you can make a region of memory executable (code) or not (data). Segment size can be byte-granular (size 1 byte to 1Meg in units of 1 byte); pages are always page-granular (size 4K to 4Gig in units of 4K). Segmentation lets you make the segment as large as necessary, with no excess (there is no internal fragmentation).
Compare paging with segmentation with respect to the amount of memory required by the address translation structures in order to convert virtual addresses to physical addresses?
Paging requires more memory overhead to maintain the translation structures. Segmentation requires just two registers per segment: one to maintain the base of the segment and the other to maintain the extent of the segment. Paging on the other hand requires one entry per page, and this entry provides the physical address in which the page is located.
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.
Definition of pure segmentation and pure paging?
In a pure segmentation architecture, segments are allocated like variable partitions, although the memory management hardware is involved in decoding addresses. Pure segmentation addresses replace the page identifier in the virtual address with a segment identifier, and find the proper segment (not page) to which to apply the offset.
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.
What is hybrid segmentation of market?
segmentation is a creative prcess. marketers normally segment markets by combining several segmentation variables rather than relaying on a single segmentation base. THERE ARE 4 METHODS OF HYBRID SEGMENTATION * Value and Life Style (VALS) * psychographic-demographic segmentation * geo-demographic segmentation * yankelovich's mind base segmentation
On which parameter is the paging ID on a GSM network?
The paging ID on a GSM network will mainly be on a radio frequency parameter. This is what allows the paging request message to have more than one MS identification.Ê
The technique of swapping items between memory and storage?
It is paging.
When did Paging You end?
Paging You ended in 1946.
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
How do you make computer use paging file as RAM?
The "paging file" is already a form of virtual memory. There is no way to use a paging file in the same way as you would normal RAM, as hard drives are hundreds of times slower than RAM.
