A repeater hub can therefore only receive and forward at a single speed. Dual-speed hubs internally consist of two hubs with a bridge between them. Since every packet is repeated on every other port, packet collisions affect the entire network, limiting its overall capacity. A network hub is an unsophisticated device in comparison with a switch.
Unlike repeater hubs, which broadcast the same data out of each port and let the devices pick out the data addressed to them, a network switch learns the Ethernet addresses of connected devices and then only forwards data to the port connected to the device to which it is addressed. [8]
A repeater/repeater hub uses a jabber timer that ends retransmission to the other ports when it expires. The timer runs for 25,000 to 50,000 bit times for 1 Mbit/s, [ 59 ] 40,000 to 75,000 bit times for 10 and 100 Mbit/s, [ 60 ] [ 61 ] and 80,000 to 150,000 bit times for 1 Gbit/s. [ 62 ]
An Ethernet repeater with multiple ports is known as an Ethernet hub. In addition to reconditioning and distributing network signals, a repeater hub assists with collision detection and fault isolation for the network. Hubs and repeaters in LANs have been largely obsoleted by modern network switches.
A control station is a base station used in a system with a repeater where the base station is used to communicate through the repeater. A temporary base is a base station used in one location for less than a year. A repeater is a type of base station that extends the range of hand-held and mobile radios.
User segments can have users' systems connected to them. Link segments (FOIRL, 10BASE-T, 10BASE-FL, or 10BASE-FB) are used to connect the network's repeaters together. The rule mandates that there can only be a maximum of five segments, connected through four repeaters, or repeater hubs, and only three of the five segments may be mixing ...

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.
