QUEUES

Queue

Queue

A linear data structure that follows the First In First Out (FIFO) principle, where the first element added is the first one to be removed.

FIFO Order

The principle in a queue where the first element added is the first one to be removed.

Dynamic Size

Property of a queue where its size can grow or shrink as elements are added or removed.

Overflow

Condition in a queue when trying to enqueue an element into a full queue.

Underflow

Condition in a queue when trying to dequeue an element from an empty queue.

Enqueue

Operation that adds an element to the rear of the queue.

Dequeue

Operation that removes the element from the front of the queue.

Front Operation

Operation that provides access to the element at the front of the queue.

IsEmpty

Operation that checks if the queue is empty.

IsFull

Operation that checks if the queue is full.

Avoids Overflow Issues

Resolves the problem of appearing full in a standard queue by utilizing circular wrap-around nature.

Simplicity in Buffer Management

Ideal for handling continuous input in fixed-size buffers like network data packets.

Complex Implementation

Circular queues can be more intricate due to wrap-around logic and managing full and empty conditions.

Fixed Size

Circular queues have a predetermined size, limiting growth without creating a new larger array.

Overflow and Underflow Conditions

Determining full or empty status can be more complex, requiring careful management to prevent errors.
