Application of stack:
- It is used in various expression conversion and evaluation - infix to post-fix or prefix evaluation.
- Stack is implicitly used by system while calling to sub routines function from main program.
- Recursion
Application of queue:
- Used by operating system in scheduling jobs and spooling (queue of print jobs)
- Disk I/O calls
- Queue is also part of the architecture of processors ex- 80386,8086

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.
How can the priority queue decrease-key operation be efficiently implemented to optimize the performance of the data structure?
To efficiently implement the decrease-key operation in a priority queue, you can use a data structure like a binary heap or Fibonacci heap. These data structures allow for efficient updates to the priority queue while maintaining the heap property, which helps optimize performance.
What is the time complexity of Dijkstra's algorithm when using a priority queue data structure?
The time complexity of Dijkstra's algorithm with a priority queue data structure is O((V E) log V), where V is the number of vertices and E is the number of edges in the graph.
Which data structure allows deletion from both ends and insertion only from one end?
Deque double ended queue
What kind of data structure is required to implement the round robin scheduling policy?
The circular queue data structure is required to implement the round robin scheduling policy. Round robin is similar to FCFS scheduling.
How do you determine symmetry of a data structure For example how do you know if a Stack or a queue or a priority queue or a double ended queue are symmetric?
You can determine symmetry of a data structure in two ways. One is when the stacks and queues data are put in the application and when the stacks are put in during run-time.
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.
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 single dimension in data structure?
Array, Stake, Queue.
What is a batch queue?
A batch queue is a system software data structure maintained by job scheduler software.
What is most appropriate data structure to implement priority queue?
heap
What is first in first out data structure?
QUEUE is the first in first out (FIFO) data structure. It is a linear data structure in which insertion of an element is done from rear end of a list and deletion of an element is done from front end of a list. For example- people in queue waiting for bus.
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.
Which data structure represents a waiting line and limits insertions to be made at the back of the data structure and limits removals to be made from the front?
Queue.
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 queue explain the basic element of queue?
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. Following are the types of queue: Linear queue Circular queue Priority queue Double ended queue ( or deque )
