What is the relationship between data flow and queue structure in information processing systems?

Data flow in information processing systems is often implemented through data structures such as queues. A queue provides ordered access to elements based on the FIFO (First In, First Out) principle, which is ideal for sequential data processing — for example, when data arrives continuously and must be processed in the same order they were received. Thus, a queue acts as a buffer, allowing for neat and sequential data flow processing, avoiding losses and ensuring synchronization between the data producer and consumer.
