Can stack be called fifo data structure?
No. A stack is a LIFO (Last In First Out) data structure.A queue is a FIFO (First In First Out) data structure.

With data structures what are the implementations of using LIFO and FIFO?
Think about what each concept means. A FIFO (First In, First Out) stack is like a supermarket queue - people are served in the order in which they arrive in line. You'd use a FIFO stack for a process that requires sequential access to data in arrival order, such as transaction processing. On the other hand, a LIFO (Last In, First Out) stack is like an elevator - the people who board last are nearest the front, so they're the first off in "processing" order. You might use a LIFO stack for something like expression parsing. For example, if you're trying to match up parens, you need to use the "nearest match" rule. That means if you have already stacked two "("s you'd want to pair the most recently-scanned one with the first closing ")" encountered and evaluate the enclosed expression. That means the ")" would pair off with the "(" at the top of your paren stack rather than the bottom; i.e. LIFO.

What data structure the pushand pop?
Push and pop are properties of a stack (also called a LIFO-- Last In, First Out-- queue).
Why is the queue data structure called a LIFO?
It isn't! A queue is a FIFO structure, not a LIFO structure. FIFO is an acronym for First-In, First-Out and is analogous with first come, first served (as per a queue of people waiting to be served). LIFO is an acronym for Last-In, First-Out, which is analogous with a stack structure, where the last element added is always placed on top of the stack while the top-most element of the stack is always the first to be removed from the stack.
Difference between a queue and a stack in brief?
In a queue, elements are placed in line; the first to get into the queue is the first to get out (FIFO - first in, first out).A stack is also a structure to store pieces of data, or objects, but the last element to get in will be the first element to get out (LIFO).In a queue, elements are placed in line; the first to get into the queue is the first to get out (FIFO - first in, first out).A stack is also a structure to store pieces of data, or objects, but the last element to get in will be the first element to get out (LIFO).In a queue, elements are placed in line; the first to get into the queue is the first to get out (FIFO - first in, first out).A stack is also a structure to store pieces of data, or objects, but the last element to get in will be the first element to get out (LIFO).In a queue, elements are placed in line; the first to get into the queue is the first to get out (FIFO - first in, first out).A stack is also a structure to store pieces of data, or objects, but the last element to get in will be the first element to get out (LIFO).
What is a stack in data structure?
A stack is a linear data structure that follows the Last In, First Out (LIFO) principle, where elements are added and removed from the same end called the top. Elements can only be added or removed from the top of the stack, making it a simple and efficient data structure for storing and accessing data.
How do you retrieve data from database in lifo manner?
Just give an auto increment value in a column and retrive it in order dec. Then you get output in lifo order

What is first in first out?
In computer programming, first-in first-out (short FIFO) describes a data structure which implements a chronological order, such that when multiple elements are added to the data structure, the normal retrieval method returns the elements in the order in which they were added. FIFO structures are often used to implement queues and buffers. The alternative commonly used chronological sorting container is LIFO, short for last-in first-out.
