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 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 is segmentation in computer memory?
memory segmentation is the process of dividing the computer memory into different overlapping segments.

You shouldn't wikianswer your homework, tardface. I can eat a pineapple in less than 2 minutes.
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).
Which one produces better solution for fragmentation segmentation or paging?
Paging generally produces better solutions for fragmentation compared to segmentation. This is because paging eliminates external fragmentation by dividing memory into fixed-size pages, allowing processes to be loaded into any available memory frame. In contrast, segmentation can lead to external fragmentation as segments can vary in size, potentially leaving unusable gaps in memory. Therefore, while both methods manage memory allocation, paging is often more efficient in handling fragmentation issues.
Advantages of paging together with segmentation?
Paging together with segmentation offers the advantages of both memory management techniques, enhancing efficiency and flexibility. Paging allows for non-contiguous memory allocation, which reduces fragmentation and optimizes memory usage. Meanwhile, segmentation provides a logical division of memory, enabling programs to be organized into meaningful units, such as functions or data structures. This combination allows for better access control, easier sharing of code, and improved overall system performance.
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?
Oh, dude, paging and segmentation are like two sides of the same coin when it comes to address translation structures. Paging requires a page table to map virtual addresses to physical addresses, which can take up a lot of memory. On the other hand, segmentation uses a segment table to do the same thing, but it might not need as much memory as paging depending on the implementation. So, like, if you're all about saving memory space, segmentation might be the way to go.
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.
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
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 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
What are the disadvantages of paging and segmentation?
Paging can lead to internal fragmentation, where allocated memory may not be fully utilized, as pages are fixed-size blocks. Segmentation, while allowing for variable-sized blocks, can suffer from external fragmentation as segments grow and shrink, potentially wasting memory space. Additionally, both methods can introduce overhead in managing the page table or segment table, impacting performance. Lastly, the combination of both techniques can complicate memory management further.
