   2. BFalsch
4. 4When a process is created, the operating system automatically adds which of the following to the address space [select all that apply]

   1. Athreads
   2. BHeap
   3. CEmpty memory space
   4. DCode
5. 5A page fault occurs. Order the series of events that takes place:
   
   OS re-executes faulting instruction [blank_start]first[blank_end]
   CPU traps to kernel [blank_start]first[blank_end]
   Page fault handler gathers data structures and necessary page [blank_start]first[blank_end]
   Page fault handler checks where fault occurred [blank_start]first[blank_end]
   MMU sends signal to CPU [blank_start]first[blank_end]
   OS loads the page provided by the page handler [blank_start]first[blank_end]
