The queue insert operation is known is enqueue.
A queue has two ends namely REAR & FRONT. After the data has been inserted in a queue ,the new element becomes REAR.The queue deletion operation is known as dequeue.
The data at the front of the queue is removed .

∙ 12y agoQueue is a linear list of elements.
With a queue, deletions can take place only one end called front, and insertion can take place only the other hand called rear.
deQueue is a linear list of elements.
With a dequeue, added and removed at either end but not in the middle.

∙ 9y agoEnqueue means to add an item to the queue, generally at the "back" of the queue. This can sometimes be called "push."
Dequeue means to remove an item from the queue, generally from the "front" of the queue. This can sometimes be called "pop."
Note that "push" and "pop" can be confused with the stack operations "push" and "pop," so "enqueue" and "dequeue" are explicit and less ambiguous.

∙ 12y agoIn queue, deletion occurs at front and insertion occurs at rear while in dequeue, insertions and deletions are made from both the ends

∙ 8y agoA dequeue describes the action of extracting an element from a queue. Not to be confused with a deque (pronounced deck) which is a double-ended queue.

What is the name for queue insertion and deletion?
The names given to these functions are implementation-specific. Below are some common examples. Adding an element to the end: enqueue, push, add Removing an element form the top: dequeue, pop, remove
When the insertion and deletion positions of the queue are interchanged then it will be a queue or not?
| --- add (enqueue) ---> ... | --- remove (dequeue) ---> |By definition, First-in-First-out is the primary characteristic of being a queue. For any given time, the position of adding an item, or enqueue, is always from the left (directions shown as above, but they are just abstraction), and deleting one, or dequeue, is always from the right. The derived property or attribute of a queue is the adding position is always >= deleting positionWhen the positions of these 2 fundamental operations are at the same position, the queue is EMPTY. And we know there is no way to be less than EMPTY of a queue, right?! Thus, insertion and deletion positions of the queue are NEVER interchanged.If they could be interchanged, then the thing you have is just a container, not a specialized container to fulfill First-IN-First-OUT (QUEUE). (the ones in the container are not served as the order they came in)
Program for dequeue in data structure?
Display function in de queue void display() { int i; if((front == -1) (front==rear+1)) printf("\n\nQueue is empty.\n"); else { printf("\n\n"); for(i=front; i<=rear; i++) printf("\t%d",queue[i]); } }
Data Structures and Algorithms in Java?
Data structures has been implemented in Java language already, you just need to import it and start using it. Data Structures are located in Java.util packages.ArrayArraylistVectorHashMapHashTableLinkedListStackQueueCollection this are the few I know.Thanks,Anandkumar.R
Can you give the explanation for various operations in a queue implementation using arrays?
The following are operations performed by queue in data structuresEnqueue (Add operation)Dequeue (Remove operation)Initialize
What is the difference between enqueue and dequeue?
Inserting element in rear end is called as enqueue, Removing element from the front end is called as dequeue.
What is the name for queue insertion and deletion?
The names given to these functions are implementation-specific. Below are some common examples. Adding an element to the end: enqueue, push, add Removing an element form the top: dequeue, pop, remove
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.
What is the purpose of the enqueue process?
the enqueue process places a new value at the back of the queue.
What queue in computing world?
Queue is a datastructure used to store values(its a linear structure).it implements FIFO policy(the element to get in first is the first to get out).Some of the operations that can be performed on Q are put(enqueue) u put elements from the rear end, get(dequeue) where the element is removed from the front end.
What exactly does 'Enqueue' mean?
To 'enqueue' something means to add it to the queue, or a list of to-do processes for, say, a program.
What is the fundamental difference between logical and physical data structures?
1) Logical data structures are structures that emphasize on data relationships and how data is related from the view of the user. 2) Physical data structures are data models that emphasize on the use of efficiently and effectively storing data in memory.
What is the meaning of enqueue?
enqueue means simply add element into the queue. generally in the back side (which is known as REAR in queue).
The need for complex data structures?

What is the linear data structures?
Linear data structures are 1-dimensional arrays, as in: vectors.
