Why stack is called LIFO data structure?

LIFO is short for “Last In First Out”. The last element pushed onto the stack will be the first element that gets popped off. If you were to pop all of the elements from the stack one at a time then they would appear in reverse order to the order that they were pushed on.

Regarding this, what is LIFO in data structure?

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. 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.

Similarly, what is a LIFO scheme and how does it relate to Stacks? Stacks. The stack is a simple but important example of an abstract data type. It is used to store elements where the Last element In is the First one Out (LIFO). Anyone with a cluttered desk or an overfull sink of washing-up will be familiar with a stack. New elements are added or pushed onto the top of the stack.

Considering this, what is stack data structure?

Stacks. A stack is a container of objects that are inserted and removed according to the last-in first-out (LIFO) principle. A stack is a limited access data structure - elements can be added and removed from the stack only at the top. push adds an item to the top of the stack, pop removes the item from the top.
