What do you mean by page-fault. when do page-fault occur. describe the action taken by the OS when page fault occurs?
If a process tries to access a page which is not present in memory or was not brought into memory. access to such page marked as invalid in page table.
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.
What is a page fault?
A page fault is an alert, such as an interrupt or exception, which indicates that a page of memory was accessed without being loaded.
What page fault in operating system?
a page fault is a hardware or software interrupt,it occurs when an access to a page that has not been brought into main memory takes place.
What is paging fault?
A page fault is an alert, such as an interrupt or exception, which indicates that a page of memory was accessed without being loaded.
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

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.
What is a page fault and a page swap?
a page fault is an interrupt (or exception) to the software raised by the hardware, when a program accesses a page that is mapped in address space, but not loaded in physical memory.Wikipedia knows...A page swap means that your page is loaded into main memory or is sent out of main memory to make place (probably due to memory-shortages or to make place for others).

What is the meaning of the page fault column in task manager?
A page fault means that the application requires some data that is not present in the physical memory or RAM. The page fault is generated when an application needs a data that has to be retrieved from the paging file on the hard drive because of its absence in the local memory.
