  2. Attack tree - Wikipedia

    en.wikipedia.org/wiki/Attack_tree

    From the bottom up, child nodes are conditions which must be satisfied to make the direct parent node true; when the root is satisfied, the attack is complete. Each node may be satisfied only by its direct child nodes. A node may be the child of another node; in such a case, it becomes logical that multiple steps must be taken to carry out an ...

  3. Node (computer science) - Wikipedia

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

    Child: A child node is a node extending from another node. For example, a computer with internet access could be considered a child node of a node representing the internet. The inverse relationship is that of a parent node. If node C is a child of node A, then A is the parent node of C. Degree: the degree of a node is the number of children of ...

  4. Network topology - Wikipedia

    en.wikipedia.org/wiki/Network_topology

    Network topology is the arrangement of the elements (links, nodes, etc.) of a communication network. [1] [2] Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, [3] industrial fieldbusses and computer networks.

  5. Complex network - Wikipedia

    en.wikipedia.org/wiki/Complex_network

    A network is called scale-free [6] [14] if its degree distribution, i.e., the probability that a node selected uniformly at random has a certain number of links (degree), follows a mathematical function called a power law. The power law implies that the degree distribution of these networks has no characteristic scale.

  6. Core–periphery structure - Wikipedia

    en.wikipedia.org/wiki/Core–periphery_structure

    This model allows for the existence of three or more partitions of node classes. However, including more classes makes modifications to the discrete model more difficult. [clarification needed] Borgatti & Everett (1999) suggest that, in order to overcome this problem, each node be assigned a measure of ‘coreness’ that will determine its ...

  7. B-tree - Wikipedia

    en.wikipedia.org/wiki/B-tree

    For this purpose, m - 1 keys from the current node, the new key inserted, one key from the parent node and j keys from the sibling node are seen as an ordered array of m + j + 1 keys. The array becomes split by half, so that ⌊ ( m + j + 1)/2 ⌋ lowest keys stay in the current node, the next (middle) key is inserted in the parent and the rest ...

  8. Hierarchical control system - Wikipedia

    en.wikipedia.org/wiki/Hierarchical_control_system

    James Albus, while at NIST, developed a theory for intelligent system design named the Reference Model Architecture (RMA), [6] which is a hierarchical control system inspired by RCS. Albus defines each node to contain these components. Behavior generation is responsible for executing tasks received from the superior, parent node. It also plans ...

  9. Butterfly network - Wikipedia

    en.wikipedia.org/wiki/Butterfly_network

    It represents each node as N(rank, column number). For example, the node at column 6 in rank 1 is represented as (1,6) and node at column 2 in rank 0 is represented as (0,2). [1] For any 'i' greater than zero, a switching node N(i,j) gets connected to N(i-1, j) and N(i-1, m), where, m is inverted bit on i th location of j.
