What else can I help you with?
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.
Where is data stored when it is in virtual memory?
Virtual memory, when not active, is written to a swapping area. The swapping area is often on a designated area of the system HDD (hard drive), or a separate HDD. If faster storage is available, it may also be on a designated semiconductor storage facility such as an SSD, SD or USB flash drive.
Virtual memory refers to your computers swapping of data currently in use between what types of memory?
explain the logical& physical memory
What program in an OS coordinates the memories by tracking which one is available which is to be allocated or deallocated and how to swap between the main memory and secondary memories?
The memory manager is the program responsible for managing memory allocation and deallocation in an operating system. It keeps track of which memory is available and allocates it to processes based on their needs. It also handles swapping data between main memory and secondary storage when the system runs low on physical memory.
What is the term that defines excessive swapping of files between RAM and virtual memory?
multitasking this answer is wrong. right answer is thrashing.
What is the difference between memory and backing storage?
i am not sure
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 the meaning of 'swapping' in computer architecture?
Swapping means to swap the values of two addresses in main memory.
What is thrashing and how it will be overcome?
when there are too many processes available and memory is low, than processor remains busy in swapping in and out the pages from disk in order to overcome it: 1) increase memory 2) reduce multi programming level
What is the three major distinctions between storage and memory?
1. There is more room in the storage than in the memory. 2. contents are retained in storage when you turn the computer off, whereas the programs or data you put into memory disappear when you shut down the computer. 3. storage is very slow compared to memory, but is more cheaper than memory
What is the difference between non-volatile memory and storage is that the memory is__________ and storage is_________.A. temporary, permanentB. permanent, temporaryC. slow, fastD. none of the above?
A
Differences between swapping and overlays?
1. In overlays there is no need for the whole program to reside in main memory .here if say if a program has two functions say f1(50k) and f2(70k) such that they are in mutual exclusion with each other then, the memory of only 70k will be allocated for both the functions and the one that is needed at a particular moment can reside in the main memory . this even saves the memory ,But it is not in case of swapping . here the whole program needs to reside in main memory 2. overlays require careful and time consuming planning while in swapping it is not needed 3. swapping needs to issue system calls for requesting and releasing memory which is not in case of overlays
