When Does Page Fault Occur? – Scaler Topics
27 juil. 2022Page faults occur when a requested page is not loaded into the memory. Page faults are detected by the Memory Management Unit (MMU). Page replacement algorithms are used to minimize the number of page faults. In this article by Scaler Topics, we are going to cover what are Disk Scheduling Algorithms in OS and why we need it.

Page fault – Wikipedia
In computing, a page fault (sometimes called PF or hard fault) [a] is an exception that the memory management unit (MMU) raises when a process accesses a memory page without proper preparations. Accessing the page requires a mapping to be added to the process’s virtual address space.

A page fault occurs when a program attempts to access data or code that is in its address space, but is not currently located in the system RAM. So when page fault occurs then following sequence of events happens : The computer hardware traps to the kernel and program counter (PC) is saved on the stack.

A page fault occurs when a program requests an address on a page that is not in the current set of memory resident pages. What happens when a page fault occurs is that the thread that experienced the page fault is put into a Wait state while the operating system finds the specific page on disk and restores it to physical memory.

A page fault is a trap to the software raised by the hardware when a program accesses a page that is mapped in the virtual address space, but not loaded in physical memory. (emphasis mine) Okay, that makes sense. But if that’s the case, why is it that whenever the process information in Process Hacker is refreshed, I see about 15 ?

What is a Page Fault? – Computer Hope
A page fault is an interruption that occurs when software attempts to access a memory block not currently stored in the system’s RAM (random-access memory). This exception tells the operating system to find the block in virtual memory to be sent to device’s storage, like an SSD (solid-state drive) or HDD (hard disk drive), to RAM.

Understanding page faults and memory swap-in/outs: when should you …
A major page fault is one that can only be satisfied by accessing the disk. A minor page fault can be satisfied by sharing pages that are already in memory. Swapping occurs when pages are written to the disk to free memory so that a major page fault can be satisfied. Swap activity is the primary performance concern when it comes to .

A page fault occurs when a program attempts to access a block of memory that is not stored in the physical memory, or RAM. The fault notifies the operating system that it must locate the data in virtual memory, then transfer it from the storage device, such as an HDD or SSD, to the system RAM.
