When does page fault occur?
A page fault occurs when a program accesses a memory page that is not currently in physical memory (RAM). This triggers the operating system to fetch the required page from secondary memory (disk) into RAM, allowing the program to continue execution.
When does the page fault occur?
A page fault occurs when a program or process needs to access a page in memory that is not currently loaded in the RAM. This prompts the operating system to retrieve the required page from secondary storage (like the hard drive) and load it into RAM.
What is demand paging in operating system?
It is a memory managermnet concept where the operating system copies the dats from the disk space to the main memory (RAM) only when is trying to access the page. it is like we have to attempt the page again, when the page fault has occured while trying to get the data.
What Actions are taken by operating system when page fault occurs?
the OS handles it by writing a page fault interrupt handler. The first thing the page fault handler will need to do is to determine the address of the page fault; you can find out this address by calling the Get_Page_Fault_Address() function (prototype in . Also, the errorCode field of theInterrupt_State data structure passed to the page fault interrupt handler contains information about the faulting access. This information is defined in the faultcode_t data type defined in. Once the fault address and fault code have been obtained, the page fault handler will need to determine an appropriate action to take
What is a fuel system fault?
That's when the fuel system is not operating as designed.
When page fault occurs?
When a page fault occurs, it means that a program is trying to access data that is currently not in physical memory. The operating system then triggers a page fault handler to bring the required data into memory from secondary storage like the hard drive. After this, the program can resume execution with the necessary data now available in physical memory.

How are page faults handled?
When a page fault occurs, the hardware cannot do anything else with the instruction that caused the page fault and thus it must transfer control to an operating system routine (this is the page fault handler). The page fault handler must then decide how to handle the page fault. It can do one of two things:- It can decide the virtual address is just simply not valid. In this case, Windows will report this error back by indicating an exception has occurred (typically STATUS_ACCESS_VIOLATION)- It can decide the virtual address is valid. In this case, Windows will find an available physical page, place the correct data in that page, update the virtual-to-physical page translation mechanism and then tell the hardware to retry the operation. When the hardware retries the operation it will find the page translation and continue operations as if nothing had actually happened.
When was operating system introduced?
I assume you mean "When was the first operating system introduced?" Seems to be in the 1950s. See the link below for a very detailed page.
When do page Page fault occur?
The Page Fault does occurs when there is unexpected event that has occurred in Windows. When the Page Fault occurs it is not possible for the hardware to function.
What is page stealing in operating system?
Some Operating Systems periodically look for pages that have not been recently referenced and add them to the Free page queue, after paging them out if they have been modified.
