Advantages and Disadvantages of Queue: In the data structure, a linear structure is used to perform different operations by collecting all the data in a particular order. This is done by the Queue which contains the data and operates by both the open ends so that the data can be inserted from one end and removed the data from the other end. A queue is a structure that includes files, lists, arrays, trees, and tables. Thus it follows the rule of first in first out (FIFO) means the data which is inserted first will be removed from the queue first. Usually, it is used when the application is made for the use of multiple users that can be easily accessed by them. For example, we make a song playlist in which we add songs and they play in the order as it is selected.

What is Queue? Advantages and Disadvantages of Queue 2022
A Queue in the data structure to perform operations by collecting data in a particular order so that the data can be used in the sequence of first in first out(FIFO). The queue is open at both ends unlike stacks where the data is stored and used in the sequence of lastly inserted will be accessed for performing any task. Thus in the queue, if any data is entered at the end it can only be used when all the other data is used and removed to use the last entered data. There are many real-life examples of the queue like going for taking a ticket then the first person in the queue will get the ticket first one more real-life example is the one-way road where vehicles that enter first go first.
In the queue, the data cannot be accessed from their places but it can be operated from the two endpoints which are data pointers front and rear. From the rear the data is inserted and then operated in a queue then from the front it is removed from the memory after utilization is done.

Below are the basic operations that must be understood before utilizing data in the queue are;
- Enqueue() – it is to add or insert data to the queue.
- Dequeue() – it is for removing or deleting data from the queue.
- Peek() – In this, any element is acquired in the front node without deleting it.
- isFull() – This is checks if queue is full.
- isNull() – It checks if the queue is empty.
In a queue when the data is added or inserted then this process is called Enqueue and when any element is removed from the queue then it is called Dequeue. The queue is created by using Array and linked list which performs the operation in first come first serve. These have many advantages while working with much data that is needed to be processed in an ordered list. Let us see its various advantages and also disadvantages.
Advantages of Queue
A queue is a structure that includes files, lists, arrays, trees, and tables following the rule of first in first out(FIFO) means the data which is inserted first will be removed from the queue first.
Below are many advantages of the queue that is used in the data structure as follows;
- Managing Large data: Queue can be used well for managing a large amount of data very efficiently by using an array and linked list so that it is huge data can be operated smoothly.
- Implement Other Data Structure: A queue has a feature to implement other data structures like arrays, lists, pointers, stacks, etc which makes it more reliable to work with the data that are needed to be operated in ordered lists.
- Speed: The queue is very much fast speed which is helpful in inter-data communication that can improve any application made with the queue.
- Useful For Multiple Users: When we want to apply one application for many or multiple users then the queue very efficiently operates on this type of requirement.
- Easy to Operate: The queue is very easy to operate as it is simple to use without making the application complex and can be easily used by beginners.
Disadvantages of Queue
The queue has multiple benefits but here are some of the advantages that come with dealing with the queue which must be considered. The following are the disadvantages of the queue
- Can be Time Consuming: The process of operating in a queue can be time-consuming because the insertion of an element and deletion will take time as it is done step by step by following the rule of first come first serve.
- Searching is Not Easy: It becomes difficult if we want to search for any element in between the ordered list in Queue.
- Limited Space Issue: In Queue if the size of it is predefined then it can be an issue as no more new elements can be entered in between so the limited space is the major problem in this.
- Difficulty in Insertion: The main problem is any element cannot be inserted in between the operation until the elements are present before being removed.
Comparison Table Between Advantages and Disadvantages of Queue
| Advantages of Queue | Disadvantages of Queue |
| It is good for operating and managing huge data. | Implements in an ordered list process can be time-consuming. |
| It implements other data structures like arrays and lists etc. | Searching for any data in this is not easy. |
| It is very fast in operating data. | Space is predefined so it is limited |
| Helpful in managing multiple users’ needs. | A new element cannot be inserted without the deletion of the old element. |
| Very easy to use or implement. | Security can be a problem. |
FAQs on Advantages and Disadvantages of Queue
Question 1.
What is a Queue? What are its uses?
Answer:
A Queue in the data structure to perform operations by collecting data in a particular order so that the data can be used in the sequence of first in first out(FIFO). The queue is open at both ends unlike stacks where the data is stored and used in the sequence of lastly inserted will be accessed for performing any task.
Usually, it is used when the application is made for the use of multiple users that can be easily accessed by them. For example, we make a song playlist in which we add songs and they play in the order as it is selected.
Here are some of the applications in the queue:
- Used to play music in mp3 players by applying as a buffer.
- Also used in making a playlist.
- Used when network issues occur while sending messages and by queue, it is stored in the server.
- It also manages interruptions in the operating system.
These were some of the uses of queues.
Question 2.
What are the basic operations that are needed to use a queue?
Answer:
The basic operations that must be understood before utilizing data in the queue are;
- Enqueue() – it is to add or insert data to the queue.
- Dequeue() – it is for removing or deleting data from the queue.
- Peek() – In this, any element is acquired in the front node without deleting it.
- isFull() – This is checks if queue is full.
- isNull() – It checks if the queue is empty.
In a queue when the data is added or inserted then this process is called Enqueue and when any element is removed from the queue then it is called Dequeue.
