What is fifo data structure?
FIFO, means "First In, First Out". An example of such a data structure is a queue.
Why does not use FIFO in stack?
A FIFO, or First In First Out is a queue.A stack is a LIFO or Last In First Out.
Why does LIFO order follows in stack and why does FIFO order follows in queue?
LIFO and stack are synonyms, so are FIFO and queue.
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.
Why in data structure queue called FIFO?
First in, first out. Because the first element entered is the first element exited. Ex: Similar to air ticketing 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.

What is a stack in data structure?
A stack in Data structure is a LIFO structure. Last In First Out. Think of it as a stack of books or a stack of trays in a cafeteria line. when you are in a line in a cafeteria you take the tray that is on the top and the worker place new washed ones also on the top. So deletion and insertion all done at one end, it is called the top of the stack. In Computer Programming Stacks are so important and have too many applications such as the evaluation of Mathematical expressions. Also note that a stack is unlike a queue structure. Queue data structure is FIFO. First In First Out as in a bank teller line.
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).

Why does LIFO order follows in stack and why does FIFO order follows in queue?
LIFO and stack are synonyms, so are FIFO and queue.
What is the difference between a queue and a stack with example?
A stack is a data structure in which last item inserted is taken out first . That's why they are known as LIFO (last in first out). Inserting an item in stack is termed as push and taking an item out from stack I s termed as pop. Stack pointer is the pointer that points to the top of the stack or that points the item at the top of the stack and help in adding or deleting the item from the top of stack. The queue is a linear data structure where operations of insertion and deletion are performed at separate ends also known as front and rear. Queue is a FIFO structure that is first in first out. types of queues : circular, linear, double ended and priority

What to Compare and contrast between stack and queue?
A stack is a data structure in which last item inserted is taken out first . That's why they are known as LIFO (last in first out). Inserting an item in stack is termed as push and taking an item out from stack I s termed as pop. Some applications of stack are : Polish notation, reversing string, backtracking , quick sort algorithm etc. The queue is a linear data structure where operations od insertion and deletion are performed at separate ends also known as front and rear. Queue is a FIFO structure that is first in first out. Whenever a new item is added to queue, rear pointer is used. and the front pointer is used when an item is deleted from the queue.
Distinct features of queue and stack?
