- CORRECT ANSWER: Parameter Passing Methods

-Reference counters: reclamation is gradual

-Mark-sweep: reclamation occurs when a request for heap space can't be filled -

CORRECT ANSWER: Garbage collection algorithms

•Pros: -May never run, if the system never runs out of heap space-It finds and frees all unused memory

•Cons:-Very slow. When it does run, the delay is noticeable to applications-Also requires

storage to support recursive - CORRECT ANSWER: Mark Sweep pros vs cons

•The run-time system allocates storage cells as requested and disconnects pointers from cells as necessary; •Mark-sweep begins whenever there is not enough contiguous memory to satisfy a request; or - when the system decides it's a good idea to collect garbage -Every heap cell has an extra bit used by the algorithm

-INITIALIZE: All cells set to garbage; e.g. extra bit = 0

-MARK: All pointers are traced into heap, and reachable cells marked as not-garbage -SWEEP: All cells in the heap are examined and any that are still marked as garbage

are returned to the free list. - CORRECT ANSWER: Mark Sweep
