is paging and swapping the same thing?

Swapping refers to copying the entire process address space, or at any rate, the non-shareable-text data segment, out to the swap device, or back, in one go (typically disk). Whereas paging refers to copying in/out one or more pages of the address space.

The swap file is a special file in the filesystem that resides amongst your system and data files. If the swapfile is in use, you should not delete it. The swap file allows the system to operate as if it has more physical memory than it actually does.

The differences between simple paging and virtual memory paging: ... In simple paging, all the pages of a process must be in main memory for process to run, unless overlays are used. But in virtual memory, not all pages of a process need be in main memory frames for the process to run. Pages may be read in as needed.

Simply put, virtual memory is a combination of RAM and disk space that running processes can use. Swap space is the portion of virtual memory that is on the hard disk, used when RAM is full. ... By definition, a 32-bit processor uses 32 bits to refer to the location of each byte of memory.

What Does mmap() Function? mmap() function or system call will create a mapping in the virtual meory of the current process. The address space consist of multiple pages and each page can be mapped some resource. We can create this mapping for a resources we want to use.

The queue is not readily searchable. You have to start from the end and might have to maintain another queue. So if you have some data, which later on you would want to be searchable, then don't even think about using a queue. Adding or deleting elements from the middle of the queue is complex as well.

The basic difference is that memory commands in unbuffered memory configurations go directly from the controller to the memory module, while in registered memory configurations the commands are sent first to the memory banks' registers prior to being sent to the modules.

Stack and Queue both are the non-primitive data structures. The main differences between stack and queue are that stack uses LIFO (last in first out) method to access and add data elements whereas Queue uses FIFO (First in first out) method to access and add data elements.

Optimal Page Replacement Algorithm. ... The target for all algorithms is to reduce number of page faults. In this algorithm, OS replaces the page that will not be used for the longest period of time in future.

Stack is a linear data structure whereas Heap is a hierarchical data structure. Stack memory will never become fragmented whereas Heap memory can become fragmented as blocks of memory are first allocated and then freed. Stack accesses local variables only while Heap allows you to access variables globally.

What is the difference between stack memory and RAM? ... Stacks are very fast to access compared to the dynamically created heap memory because of their structured storage and high probable matching to the C.P.U cache. RAM,my dear friend is just the p. Stack is the physical space allocated to each thread in its runtime.

With demand cleaning, a page is written out to secondary memory only when it has been selected for replacement. A pre-cleaning policy writes modified pages before their page frames are needed so that pages can be written out in batches.

Swap is hard disk space used as RAM. It is (relatively speaking) very slow, but stops computers from crashing when they are trying to deal with more data then their RAM can handle. To stop processes from using swap — install more RAM.
