2. Network switch - Wikipedia

   en.wikipedia.org/wiki/Network_switch

   A switch is more intelligent than an Ethernet hub, which simply retransmits packets out of every port of the hub except the port on which the packet was received, unable to distinguish different recipients, and achieving an overall lower network efficiency. An Ethernet switch operates at the data link layer (layer 2) of the OSI model to create ...

3. Ethernet hub - Wikipedia

   en.wikipedia.org/wiki/Ethernet_hub

   4-port 10BASE-T Ethernet hub with selectable MDI-X/MDI port 8-port Ethernet hub with one 10BASE2 connector and eight 10BASE-T ports. An Ethernet hub, active hub, network hub, repeater hub, multiport repeater, or simply hub [a] is a network hardware device for connecting multiple Ethernet devices together and making them act as a single network segment.

4. Ethernet - Wikipedia

   en.wikipedia.org/wiki/Ethernet

   A core Ethernet switch. Simple switched Ethernet networks, while a great improvement over repeater-based Ethernet, suffer from single points of failure, attacks that trick switches or hosts into sending data to a machine even if it is not intended for it, scalability and security issues with regard to switching loops, broadcast radiation, and ...

5. Fully switched network - Wikipedia

   en.wikipedia.org/wiki/Fully_switched_network

   A fully switched network is a computer network which uses only network switches rather than Ethernet hubs on Ethernet networks. [1] The switches provide a dedicated connection to each workstation. A switch allows for many conversations to occur simultaneously. Before switches, networks based on hubs data could only allow transmission in one ...

7. Network topology - Wikipedia

   en.wikipedia.org/wiki/Network_topology

   A network switch is a device that forwards and filters OSI layer 2 datagrams between ports based on the destination MAC address in each frame. [16] A switch is distinct from a hub in that it only forwards the frames to the physical ports involved in the communication rather than all ports connected.
