What is Queue / Buffer
A Queue is a data structure that follows a First In First Out (FIFO) principle, where the first element added to the queue will be the first one to be removed. It is widely used in task scheduling and event handling in operating systems. The implementation of a queue can vary, using structures such as arrays or linked lists. Understanding queues is essential for managing processes and resources in multi-tasking environments.
On the other hand, a Buffer is a temporary storage area in memory, aimed at improving data processing efficiency. Buffers play a crucial role in data transmission, as they help mitigate speed differences between devices, enhancing overall performance. Buffers are commonly used in scenarios like audio and video streaming, and network data packet transfers. Together, queues and buffers are essential components in modern computer systems, particularly in real-time data processing and big data applications.
