• Key Concepts: 
  Page faults are a type of error that occurs when a program attempts to access a page of memory that is not currently in the computer’s main memory. This can happen when the program tries to access a page that has been swapped out to disk, or when the program tries to access a page that does not exist. In either case, the program will be unable to access the page and will generate an error. 
  
  How to use it: 
  Page faults can be avoided by ensuring that all pages of memory are available in main memory before the program attempts to access them. This can be done by pre-loading all necessary pages into main memory before the program is executed, or by using virtual memory techniques such as paging and segmentation. 
  
  Tips & Tricks: 
  Page faults can be reduced by optimizing the code so that it only accesses pages of memory that are already in main memory. This can be done by avoiding unnecessary accesses to pages of memory, and by ensuring that all necessary pages are pre-loaded into main memory before the program is executed. 
  
  Related Information: 
  Page faults are related to other types of errors such as segmentation faults and bus errors. These errors occur when a program attempts to access a page of memory that does not exist or is not accessible due to hardware or software limitations.
