<human>:  What is the differences between the terms FIFO and LIFO?
<bot>: The main difference between FIFO and LIFO is the order in which items are processed. FIFO stands for First-In-First-Out, which means that items are processed in the order that they come in. LIFO stands for Last-In-First-Out, which means that the last item that came in is the first item that is processed.
