  2. 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.

  3. 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.

  4. Network scheduler - Wikipedia

    en.wikipedia.org/wiki/Network_scheduler

    Packets queuing in a FIFO (first in, first out) data structure.. A network scheduler, also called packet scheduler, queueing discipline (qdisc) or queueing algorithm, is an arbiter on a node in a packet switching communication network.

  5. FIFO - Wikipedia

    en.wikipedia.org/wiki/FIFO

    FIFO in stock rotation, particularly to avoid food spoilage; FIFO (computing and electronics), a method of queuing or memory management Queue (abstract data type), data abstraction of the queuing concept; FIFO and LIFO accounting, methods used in managing inventory and financial matters

  6. Inventory - Wikipedia

    en.wikipedia.org/wiki/Inventory

    LIFO considers the last unit arriving in inventory as the first one sold. Which method an accountant selects can have a significant effect on net income and book value and, in turn, on taxation. Using LIFO accounting for inventory, a company generally reports lower net income and lower book value, due to the effects of inflation.

  7. 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.

  8. 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

  9. Circular buffer - Wikipedia

    en.wikipedia.org/wiki/Circular_buffer

    In other words, the circular buffer is well-suited as a FIFO (first in, first out) buffer while a standard, non-circular buffer is well suited as a LIFO (last in, first out) buffer. Circular buffering makes a good implementation strategy for a queue that has fixed maximum size. Should a maximum size be adopted for a queue, then a circular ...
