Prerequisite – FIFO (First-In-First-Out) approach in Programming
FIFO is an abbreviation for first in, first out. It is a method for handling data structures where the first element is processed first and the newest element is processed last.
Real life example:
LIFO is an abbreviation for Last in, first out is same as fist in, last out (FILO). It is a method for handling data structures where the last element is processed first and the first element is processed last.
Real life example:
Below is a comparison of FIFO vs. LIFO:
|It stands for First-In-First-Out approach in programming.||It stands for Last-In-First-Out approach in programming.|
|In this, the new element is inserted below the existing element, So that the oldest element can be at the top and taken out first.||In this, the new element is inserted above the existing element, So that the newest element can be at the top and taken out first.|
|Therefore, the First element to be entered in this approach, gets out First.||Therefore, the First element to be entered in this approach, gets out Last.|
|In computing, FIFO approach is used as an operating system algorithm, which gives every process CPU time in the order they arrive.||In computing, LIFO approach is used as a queuing theory that refers to the way items are stored in types of data structures.|
|The data structure that implements FIFO is Queue.||The data structure that implements LIFO is Stack.|
