  2. Boltzmann machine - Wikipedia

    en.wikipedia.org/wiki/Boltzmann_machine

    A deep Boltzmann machine (DBM) is a type of binary pairwise Markov random field ( undirected probabilistic graphical model) with multiple layers of hidden random variables. It is a network of symmetrically coupled stochastic binary units. It comprises a set of visible units and layers of hidden units .

  3. Transmission medium - Wikipedia

    en.wikipedia.org/wiki/Transmission_medium

    A transmission medium is a system or substance that can mediate the propagation of signals for the purposes of telecommunication. Signals are typically imposed on a wave of some kind suitable for the chosen medium. For example, data can modulate sound, and a transmission medium for sounds may be air, but solids and liquids may also act as the ...

  4. Tensor calculus - Wikipedia

    en.wikipedia.org/wiki/Tensor_calculus

    v. t. e. In mathematics, tensor calculus, tensor analysis, or Ricci calculus is an extension of vector calculus to tensor fields ( tensors that may vary over a manifold, e.g. in spacetime ). Developed by Gregorio Ricci-Curbastro and his student Tullio Levi-Civita, [ 1] it was used by Albert Einstein to develop his general theory of relativity.

  5. Network topology - Wikipedia

    en.wikipedia.org/wiki/Network_topology

    Network topology is the topological [ 4] structure of a network and may be depicted physically or logically. It is an application of graph theory [ 3] wherein communicating devices are modeled as nodes and the connections between the devices are modeled as links or lines between the nodes. Physical topology is the placement of the various ...

  6. Networking hardware - Wikipedia

    en.wikipedia.org/wiki/Networking_hardware

    Networking hardware, also known as network equipment or computer networking devices, are electronic devices that are required for communication and interaction between devices on a computer network. Specifically, they mediate data transmission in a computer network. [ 1] Units which are the last receiver or generate data are called hosts, end ...

  7. Network theory - Wikipedia

    en.wikipedia.org/wiki/Network_theory

    Network science. In mathematics, computer science and network science, network theory is a part of graph theory. It defines networks as graphs where the vertices or edges possess attributes. Network theory analyses these networks over the symmetric relations or asymmetric relations between their (discrete) components.

  8. Digital electronics - Wikipedia

    en.wikipedia.org/wiki/Digital_electronics

    Digital electronics is a field of electronics involving the study of digital signals and the engineering of devices that use or produce them. This is in contrast to analog electronics which work primarily with analog signals. Despite the name, digital electronics designs includes important analog design considerations.

  9. TCP congestion control - Wikipedia

    en.wikipedia.org/wiki/TCP_congestion_control

    Transmission Control Protocol (TCP) uses a congestion control algorithm that includes various aspects of an additive increase/multiplicative decrease (AIMD) scheme, along with other schemes including slow start [ 1] and a congestion window (CWND), to achieve congestion avoidance. The TCP congestion-avoidance algorithm is the primary basis for ...
