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 ...
A node is a basic unit of a data structure, such as a linked list or tree data structure. Nodes contain data and also may link to other nodes. Links between nodes are often implemented by pointers. In graph theory, the image provides a simplified view of a network, where each of the numbers represents a different node.
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 ...
Relationships may be identified among various types of nodes, including organizations, people and transactions. Link analysis has been used for investigation of criminal activity (fraud, counterterrorism, and intelligence), computer security analysis, search engine optimization, market research, medical research, and art.
RINA literature follows the general theory of Jerry Saltzer on addressing and naming. According to Saltzer, four elements need to be identified: applications, nodes, attachment points and paths. [4] An application can run in one or more nodes and should be able to move from one node to another without losing its identity in the network.
This result was the first to show that computational complexity theory can be used to devise malware that is robust against reverse-engineering. A growing area of computer virus research is to mathematically model the infection behavior of worms using models such as Lotka–Volterra equations, which has been applied in the study of biological ...
In graph theory and theoretical computer science, the level ancestor problem is the problem of preprocessing a given rooted tree T into a data structure that can determine the ancestor of a given node at a given distance from the root of the tree. More precisely, let T be a rooted tree with n nodes, and let v be an arbitrary node of T.
Fig. 1: A sketch of a small network displaying community structure, with three groups of nodes with dense internal connections and sparser connections between groups.. In the study of networks, such as computer and information networks, social networks and biological networks, a number of different characteristics have been found to occur commonly, including the small-world property, heavy ...
