LIFO is a method of processing data in which the last items that are entered are also extracted first.

LIFO’s full-form is ” Last In, First Out .” The reverse of LIFO is FIFO ( First In, First Out ), in which items are also removed according to which they have been entered accordingly.

To understand LIFO better, think of a deck of cards, which is made by placing one card on top of the other, for which it starts from the bottom. Once the deck is stacked completely, you can also slowly remove the cards, for which you have to remove the cards from the top.

This process is an example of the LIFO method, because the last cards that have been placed in the deck are the first ones to be removed.

The LIFO method is sometimes used by computers when data is extracted from an array or data buffer. When a program needs the most recent information to access , then the LIFO method is used in this way.

At the same time, when the information is retrieved as if they were entered, then the FIFO method is used.
