2. FIFO (computing and electronics) - Wikipedia

   en.wikipedia.org/wiki/FIFO_(computing_and...

   FIFO's opposite is LIFO, last-in-first-out, where the youngest entry or "top of the stack" is processed first. [2] A priority queue is neither FIFO or LIFO but may adopt similar behaviour temporarily or by default. Queueing theory encompasses these methods for processing data structures, as well as interactions between strict-FIFO queues.

3. Queue (abstract data type) - Wikipedia

   en.wikipedia.org/wiki/Queue_(abstract_data_type)

   The operations of a queue make it a first-in-first-out (FIFO) data structure. In a FIFO data structure, the first element added to the queue will be the first one to be removed. This is equivalent to the requirement that once a new element is added, all elements that were added before have to be removed before the new element can be removed.

4. Scheduling (computing) - Wikipedia

   en.wikipedia.org/wiki/Scheduling_(computing)

   A sample thread pool (green boxes) with a queue (FIFO) of waiting tasks (blue) and a queue of completed tasks (yellow) First in, first out , also known as first come, first served (FCFS), is the simplest scheduling algorithm. FIFO simply queues processes in the order that they arrive in the ready queue.

7. LIFO - Wikipedia

   en.wikipedia.org/wiki/LIFO

   FIFO and LIFO accounting Stack (abstract data type) , in computing, a collection data structure providing l ast- i n- f irst- o ut semantics; also called a LIFO queue LIFO (education) , a layoff policy

8. Fair queuing - Wikipedia

   en.wikipedia.org/wiki/Fair_queuing

   Fair queuing uses one queue per packet flow and services them in rotation, such that each flow can "obtain an equal fraction of the resources". [1] [2]The advantage over conventional first in first out (FIFO) or priority queuing is that a high-data-rate flow, consisting of large packets or many data packets, cannot take more than its fair share of the link capacity.

9. Stack (abstract data type) - Wikipedia

   en.wikipedia.org/wiki/Stack_(abstract_data_type)

   The order in which an element added to or removed from a stack is described as last in, first out, referred to by the acronym LIFO. [ nb 1 ] As with a stack of physical objects, this structure makes it easy to take an item off the top of the stack, but accessing a datum deeper in the stack may require removing multiple other items first.
