  2. Heap (data structure) - Wikipedia

    en.wikipedia.org/wiki/Heap_(data_structure)

    Example of a binary max-heap with node keys being integers between 1 and 100. In computer science, a heap is a tree-based data structure that satisfies the heap property: In a max heap, for any given node C, if P is the parent node of C, then the key (the value) of P is greater than or equal to the key of C.

  3. Heap - Wikipedia

    en.wikipedia.org/wiki/Heap

    Heap (data structure), a data structure commonly used to implement a priority queue; Heap (mathematics), a generalization of a group; Heap (programming) (or free store), an area of memory for dynamic memory allocation; Heapsort, a comparison-based sorting algorithm; Heap overflow, a type of buffer overflow that occurs in the heap data area

  4. Data segment - Wikipedia

    en.wikipedia.org/wiki/Data_segment

    This shows the typical layout of a simple computer's program memory with the text, various data, and stack and heap sections. The data segment contains initialized static variables, i.e. global variables and local static variables which have a defined value and can be modified. Examples in C include:

  5. Pointer (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Pointer_(computer_programming)

    Most structured and object-oriented languages provide an area of memory, called the heap or free store, from which objects are dynamically allocated. The example C code below illustrates how structure objects are dynamically allocated and referenced. The standard C library provides the function malloc() for allocating memory blocks from the ...

  6. Binary heap - Wikipedia

    en.wikipedia.org/wiki/Binary_heap

    Example of a complete binary max-heap Example of a complete binary min heap. A binary heap is a heap data structure that takes the form of a binary tree.Binary heaps are a common way of implementing priority queues.

  7. Garbage collection (computer science) - Wikipedia

    en.wikipedia.org/wiki/Garbage_collection...

    Stop-and-copy garbage collection in a Lisp architecture: [1] Memory is divided into working and free memory; new objects are allocated in the former. When it is full (depicted), garbage collection is performed: All data structures still in use are located by pointer tracing and copied into consecutive locations in free memory.

  8. Code segment - Wikipedia

    en.wikipedia.org/wiki/Code_segment

    This shows the typical layout of a simple computer's program memory with the text, various data, and stack and heap sections.. In computing, a code segment, also known as a text segment or simply as text, is a portion of an object file or the corresponding section of the program's virtual address space that contains executable instructions.

  9. Database storage structures - Wikipedia

    en.wikipedia.org/wiki/Database_storage_structures

    Heap files are lists of unordered records of variable size. Although sharing a similar name, heap files are widely different from in-memory heaps. In-memory heaps are ordered, as opposed to heap files. Simplest and most basic method insert efficient, with new records added at the end of the file, providing chronological order
