  2. Social network analysis - Wikipedia

    en.wikipedia.org/wiki/Social_network_analysis

    A social network diagram displaying friendship ties among a set of Facebook users. Social network analysis (SNA) is the process of investigating social structures through the use of networks and graph theory. [1]

  3. Social network - Wikipedia

    en.wikipedia.org/wiki/Social_network

    Diagram: section of a large-scale social network. Large-scale networks: Large-scale network is a term somewhat synonymous with "macro-level." It is primarily used in social and behavioral sciences, and in economics. Originally, the term was used extensively in the computer sciences (see large-scale network mapping).

  4. Computer network diagram - Wikipedia

    en.wikipedia.org/wiki/Computer_network_diagram

    A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. Computer network diagrams form an important part of network documentation.

  5. Persistent homology - Wikipedia

    en.wikipedia.org/wiki/Persistent_homology

    See homology for an introduction to the notation.. Persistent homology is a method for computing topological features of a space at different spatial resolutions. More persistent features are detected over a wide range of spatial scales and are deemed more likely to represent true features of the underlying space rather than artifacts of sampling, noise, or particular choice of parameters.

  6. Systems Network Architecture - Wikipedia

    en.wikipedia.org/wiki/Systems_Network_Architecture

    PU5 nodes are host computer systems [26] The term 37xx refers to IBM's family of SNA communications controllers. The 3745 supports up to eight high-speed T1 circuits, the 3725 is a large-scale node and front-end processor for a host, and the 3720 is a remote node that functions as a concentrator and router .

  7. State diagram - Wikipedia

    en.wikipedia.org/wiki/State_diagram

    A state diagram for a door that can only be opened and closed. A state diagram is used in computer science and related fields to describe the behavior of systems. State diagrams require that the system is composed of a finite number of states. Sometimes, this is indeed the case, while at other times this is a reasonable abstraction.

  8. Block diagram - Wikipedia

    en.wikipedia.org/wiki/Block_diagram

    A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. [1] They are heavily used in engineering in hardware design , electronic design , software design , and process flow diagrams .

  9. Cluster diagram - Wikipedia

    en.wikipedia.org/wiki/Cluster_diagram

    In computer science more complex diagrams of computer networks, computer architecture, file systems and internet can be considered cluster diagrams.; In information visualization specific visual representation of large-scale collections of non-numerical information are sometimes drawn in the shape of a cluster diagram.
