What is a page fault?
Rating:
A page fault is an interrupt that occurs when a program or data, when requested, is not present in the computer's main memory. In the event of a page fault, the operating system searches the data in the virtual memory of the computer. If data cannot be mapped to the virtual memory also, an invalid page fault occurs. Invalid page faults are very difficult to diagnose. Due to invalid page faults, an operating system generates several types of errors. A few of them are as follows:
- Iexplorer.exe has generated errors and must be shut down.
- Page could not be displayed.
- An access violation occurred in MSHTML.DLL.
- Could not open the search page.
