A queue is a linear data structure that follows a First In First Out (
FIFO
) order.
FIFO means elements are added to the end of the queue and
removed
from the front.
Queues are commonly used to
manage
the flow of data and to ensure that data is processed in a timely manner.
Queues can be
implemented
using data structures, such as arrays, linked lists, or circular buffers
Queues can have a
fixed
size, or they can be dynamic and expand as per users need.
Queues can be
bounded
, meaning that they have a maximum size, or unbounded, meaning that they can grow indefinitely.
Queues can be used in a variety of
applications
, including task scheduling, communication between threads, data buffering , etc.
