  2. inode - Wikipedia

    en.wikipedia.org/wiki/Inode

    The inode (index node) is a data structure in a Unix-style file system that describes a file-system object such as a file or a directory. Each inode stores the attributes and disk block locations of the object's data. [1] File-system object attributes may include metadata (times of last change, [2] access, modification), as well as owner and ...

  3. Graceful exit - Wikipedia

    en.wikipedia.org/wiki/Graceful_exit

    In a language that supports formal exception handling, a graceful exit may be the final step in the handling of an exception. In other languages graceful exits can be implemented with additional statements at the locations of possible errors.

  4. Tree (abstract data type) - Wikipedia

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

    An internal node (also known as an inner node, inode for short, or branch node) is any node of a tree that has child nodes. Similarly, an external node (also known as an outer node, leaf node, or terminal node) is any node that does not have child nodes. The height of a node is the length of the longest downward path to a leaf from that node ...

  5. Parse tree - Wikipedia

    en.wikipedia.org/wiki/Parse_tree

    A nonterminal function is a function (node) which is either a root or a branch in that tree whereas a terminal function is a function (node) in a parse tree which is a leaf. For binary trees (where each parent node has two immediate child nodes), the number of possible parse trees for a sentence with n words is given by the Catalan number C n ...

  6. Exposed node problem - Wikipedia

    en.wikipedia.org/wiki/Exposed_node_problem

    When a node hears an RTS from a neighboring node, but not the corresponding CTS, that node can deduce that it is an exposed node and is permitted to transmit to other neighboring nodes. [ 1 ] If the nodes are not synchronised (or if the packet sizes are different or the data rates are different) the problem may occur that the sender will not ...

  7. Linked list - Wikipedia

    en.wikipedia.org/wiki/Linked_list

    function insertAfter(Node node, Node newNode) if node = null // assume list is empty newNode.next := newNode else newNode.next := node.next node.next := newNode update lastNode variable if necessary Suppose that "L" is a variable pointing to the last node of a circular linked list (or null if the list is empty).

  8. Terminal node - Wikipedia

    en.wikipedia.org/wiki/Terminal_node

    Leaf node, a node of a tree data structure that has no child nodes. Lymph node , a terminal lymph node in the lymphatic system. Topics referred to by the same term

  9. Merkle tree - Wikipedia

    en.wikipedia.org/wiki/Merkle_tree

    One simple fix is defined in Certificate Transparency: when computing leaf node hashes, a 0x00 byte is prepended to the hash data, while 0x01 is prepended when computing internal node hashes. [13] Limiting the hash tree size is a prerequisite of some formal security proofs , and helps in making some proofs tighter.
