  2. Stack (abstract data type) - Wikipedia

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

    Similarly to a stack of plates, adding or removing is only practical at the top. Simple representation of a stack runtime with push and pop operations. In computer science, a stack is an abstract data type that serves as a collection of elements with two main operations: Push, which adds an element to the collection, and

  3. Queue (abstract data type) - Wikipedia

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

    A queue may be implemented as circular buffers and linked lists, or by using both the stack pointer and the base pointer. Queues provide services in computer science , transport , and operations research where various entities such as data, objects, persons, or events are stored and held to be processed later.

  4. Double-ended queue - Wikipedia

    en.wikipedia.org/wiki/Double-ended_queue

    Both the basic and most common list types in computing, queues and stacks can be considered specializations of deques, and can be implemented using deques. A deque is a data structure that allows users to perform push and pop operations at both ends, providing flexibility in managing the order of elements.

  5. Abstract data type - Wikipedia

    en.wikipedia.org/wiki/Abstract_data_type

    Despite not being part of the interface, the constraints are still important to the definition of the ADT; for example a stack and a queue have similar add element/remove element interfaces, but it is the constraints that distinguish last-in-first-out from first-in-first-out behavior.

  6. Data structure - Wikipedia

    en.wikipedia.org/wiki/Data_structure

    A data structure known as a hash table.. In computer science, a data structure is a data organization and storage format that is usually chosen for efficient access to data. [1] [2] [3] More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data, [4] i.e., it is an algebraic structure about data.

  7. Peek (data type operation) - Wikipedia

    en.wikipedia.org/wiki/Peek_(data_type_operation)

    Priority queue (such as a heap) Double-ended queue (deque) Double-ended priority queue (DEPQ) Single-ended types, such as stack, generally only admit a single peek, at the end that is modified. Double-ended types, such as deques, admit two peeks, one at each end. Names for peek vary. "Peek" or "top" are common for stacks, while for queues ...

  8. Priority queue - Wikipedia

    en.wikipedia.org/wiki/Priority_queue

    Stacks and queues can be implemented as particular kinds of priority queues, with the priority determined by the order in which the elements are inserted. In a stack, the priority of each inserted element is monotonically increasing; thus, the last element inserted is always the first retrieved.

  9. Queue - Wikipedia

    en.wikipedia.org/wiki/Queue

    Queue (abstract data type), a type of data structure in computer science Circular queue; Double-ended queue, also known as a deque; Priority queue; FIFO (computing and electronics) Load (computing) or queue, system load of a computer's operating system; Message queue; Queueing theory, the study of wait lines
