2. 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.

3. List of data structures - Wikipedia

   en.wikipedia.org/wiki/List_of_data_structures

   This is a list of well-known data structures. For a wider list of terms, see list of terms relating to algorithms and data structures. For a comparison of running times for a subset of this list see comparison of data structures.

4. List of abstractions (computer science) - Wikipedia

   en.wikipedia.org/wiki/List_of_abstractions...

   Common data structures and their usage Data Structure Definition Usage Array: A fixed-size collection of elements of the same data type, accessible by indices. General-purpose storage and retrieval, basis of many more complex structures. List: An abstract data type that represents a sequence of values, where the same value may occur more than once.

5. Tree (abstract data type) - Wikipedia

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

   In computer science, a tree is a widely used abstract data type that represents a hierarchical tree structure with a set of connected nodes. Each node in the tree can be connected to many children (depending on the type of tree), but must be connected to exactly one parent, [ 1 ] [ 2 ] except for the root node, which has no parent (i.e., the ...

6. Graph (abstract data type) - Wikipedia

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

   UML class diagram of a Graph (abstract data type) The basic operations provided by a graph data structure G usually include: [1] adjacent(G, x, y): tests whether there is an edge from the vertex x to the vertex y; neighbors(G, x): lists all vertices y such that there is an edge from the vertex x to the vertex y;

7. Abstraction (computer science) - Wikipedia

   en.wikipedia.org/wiki/Abstraction_(computer_science)

   Abstraction is a fundamental concept in computer science and software engineering, especially within the object-oriented programming paradigm. [3] Examples of this include: the usage of abstract data types to separate usage from working representations of data within programs; [4]

8. Linked list - Wikipedia

   en.wikipedia.org/wiki/Linked_list

   Linked lists are among the simplest and most common data structures. They can be used to implement several other common abstract data types, including lists, stacks, queues, associative arrays, and S-expressions, though it is not uncommon to implement those data structures directly without using a linked list as the basis.

9. Data (computer science) - Wikipedia

   en.wikipedia.org/wiki/Data_(computer_science)

   Object-oriented programming uses two basic concepts for understanding data and software: The taxonomic rank-structure of classes, which is an example of a hierarchical data structure; and; at run time, the creation of references to in-memory data-structures of objects that have been instantiated from a class library.
