title: FIFO cache vs LRU cache
body: <p>I'm really sorry for such simple question. I just want to be sure that I understand FIFO cache model correctly and I hope that someone will help me with that :) LRU cache deletes entry that was accessed least recently if the cache is full. FIFO deletes the entry that was added earlier(?) than other entries if the cache needs free space (for example if 'a' - 'v' - 'f' - 'k' is entries in the cache and 'a' is the oldest entry then cache will delete 'a' if it will need free space). </p>
  
  <p>Am I right? </p>
