Historically, the main reason for purchasing hubs rather than switches was their price. By the early 2000s, there was little price difference between a hub and a low-end switch. [11] Hubs can still be useful in special circumstances: For inserting a protocol analyzer into a network connection, a hub is an alternative to a network tap or port ...
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.
A hub provides a point-to-multipoint (or simply multipoint) circuit in which all connected client nodes share the network bandwidth. A switch on the other hand provides a series of point-to-point circuits, via microsegmentation, which allows each client node to have a dedicated circuit and the added advantage of having full-duplex connections.
A switching loop or bridge loop occurs in computer networks when there is more than one Layer 2 path between two endpoints (e.g. multiple connections between two network switches or two ports on the same switch connected to each other).
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.
Hub with three MDI-X ports and one switchable port, circa 1998 Switch showing one logical port, 16, with two physical ports, one in each conductor arrangement: MDI-X (the norm for a hub or switch), labelled 16x, and MDI, labelled Uplink, for connecting to another hub or switch with a normal straight-through cable

A hub is a component of a network with a high-degree node. Hubs have a significantly larger number of links in comparison with other nodes in the network. The number of links for a hub in a scale-free network is much higher than for the biggest node in a random network, keeping the size N of the network and average degree <k> constant. The ...
