⁉️What is Queue?
A Queue is a data structure that stores elements in a First-In-First-Out
(FIFO) order.
In a queue, elements are added from the back, known as
the "enqueue" operation, and removed from the front, known as the
"dequeue" operation.
Queues are used to model scenarios where the order
of processing elements matters, such as in scheduling tasks or handling
requests.
👍Advantages of Queue:
- Provides a simple and effective way of managing elements in a sequential manner.
- Allows easy addition of elements to the back of the queue.
- Enables easy removal of elements from the front of the queue.
- Provides a predictable behavior in terms of element ordering.
👎Disadvantages of Queue:
- Queues can have a fixed size, which can lead to issues if the number of elements exceeds this size.
- The time complexity of certain operations, such as searching for an element, can be slow.
📌Use Cases:
- Queues are used in operating systems to manage the order in which processes are executed.
- Queues are used in networking to manage the order in which packets are transmitted.
- Queues are used in web servers to handle incoming requests and allocate resources to them.
- Queues are used in printers to manage the order in which print jobs are executed.
🖊️Summary:
A queue is a data structure that allows for elements to be added to the back and removed from the front in a First-In-First-Out (FIFO) order. It provides a simple and effective way of managing elements in a sequential manner, making it useful in a wide range of applications.
