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...

Which data structure allows deleting data elements from front and inserting at rear?
Insertion at the tail and extraction from the head is a first in first out structure (LIFO), more commonly known as a queue. Typical implementations employ a singly-linked list with one pointer for the head and another for the tail while each node points to the next. ...
What are the data structures that are under the LIFO?

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...
