Stands for "Last In, First Out." LIFO is a method of processing
data in which the last items entered are the first to be
removed. This is the opposite of LIFO is FIFO (First In, First
Out), in which items are removed in the order they have been
entered.  To better understand LIFO, imagine stacking a deck of
cards by placing one card on top of the other, starting from the
bottom. Once the deck has been fully stacked, you begin to
remove the cards, starting from the top. This process is an
example of the LIFO method, because the last cards to be placed
on the deck are the first ones to be removed.  The LIFO method
is sometimes used by computers when extracting data from an
array or data buffer. When a program needs to access the most
recent information entered, it will use the LIFO method. When
information needs to be retrieved in the order it was entered,
the FIFO method is used.  Updated: N/A
