  2. Networking hardware - Wikipedia

    en.wikipedia.org/wiki/Networking_hardware

    Networking devices includes a broad range of equipment which can be classified as core network components which interconnect other network components, hybrid components which can be found in the core or border of a network and hardware or software components which typically sit on the connection point of different networks.

  3. Computer network - Wikipedia

    en.wikipedia.org/wiki/Computer_network

    A nanoscale network has key components implemented at the nanoscale, including message carriers, and leverages physical principles that differ from macroscale communication mechanisms. Nanoscale communication extends communication to very small sensors and actuators such as those found in biological systems and also tends to operate in ...

  4. Computer network diagram - Wikipedia

    en.wikipedia.org/wiki/Computer_network_diagram

    The physical network topology can be directly represented in a network diagram, as it is simply the physical graph represented by the diagrams, with network nodes as vertices and connections as undirected or direct edges (depending on the type of connection). [3] The logical network topology can be inferred from the network diagram if details ...

  5. Network layer - Wikipedia

    en.wikipedia.org/wiki/Network_layer

    The network layer provides the means of transferring variable-length network packets from a source to a destination host via one or more networks. Within the service layering semantics of the OSI (Open Systems Interconnection) network architecture, the network layer responds to service requests from the transport layer and issues service requests to the data link layer.

  6. 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.

  7. Network architecture - Wikipedia

    en.wikipedia.org/wiki/Network_architecture

    Network architecture is the design of a computer network.It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used.

  8. Network packet - Wikipedia

    en.wikipedia.org/wiki/Network_packet

    In the seven-layer OSI model of computer networking, packet strictly refers to a protocol data unit at layer 3, the network layer. [2] A data unit at layer 2, the data link layer, is a frame. In layer 4, the transport layer, the data units are segments and datagrams.

  9. Network switch - Wikipedia

    en.wikipedia.org/wiki/Network_switch

    A network switch is a multiport network bridge that uses MAC addresses to forward data at the data link layer (layer 2) of the OSI model. Some switches can also forward data at the network layer (layer 3) by additionally incorporating routing functionality. Such switches are commonly known as layer-3 switches or multilayer switches. [2]
