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.

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.
What is LIFO in Data Structure?
LIFO stands for Last In First Out. Ex: Stack
What data structure the pushand pop?

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).
Where can Java Queue be downloaded?
A 'queue' is a particular kind of data structure that Java is capable of working with. There are no products called "Java Queue" and is thus not something one can download.
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.
What is fifo data structure?
FIFO, means "First In, First Out". An example of such a data structure is a queue.
What is the need of circular queue in data structures?
Circular queue is a linear data structure that follows the First In First Out principle. A re-buffering problem often occurs for each dequeue operation in a standard queue data structure. This is solved by using a circular queue which joins the front and rear ends of a queue.
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
What are types of Queue?
Queue is a data structure which is based on FIFO that is first in first out. Following are the types of queue: Linear queue Circular queue Priority queue Double ended queue ( or deque )
What is a queue computer data structure?
A queue is a data structure that allows adding elements at one end (the tail of the queue), and removing them from the other end (the head).Adding at the tail is sometimes called enqueueing, and removing from the head is dequeueing.Inserting or removing elements at other places is not permitted.There may also be operations to examine the element at the head of the queue without removing it (peeking), and to find out how many elements there are in the queue.
What is single dimension in data structure?
Array, Stake, Queue.
