A switch is a device in a computer network that connects other devices together. Multiple data cables are plugged into a switch to enable communication between different networked devices. Switches manage the flow of data across a network by transmitting a received network packet only to the one or more devices for which the packet is intended.
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.
An Ethernet crossover cable is a type of twisted pair Ethernet cable used to connect computing devices together directly that would normally be connected via a network switch, Ethernet hub or router, such as directly connecting two personal computers via their network adapters.
USB 3 uses tinned copper stranded AWG-28 cables [7] with 90 ± 7 Ω impedance for its high-speed differential pairs. Electrical signalling uses a linear feedback shift register and 8b/10b encoding with spread spectrum clocking , sent at a nominal 1 Volt with a 100 mV receiver threshold; the receiver uses equalization training.
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

Standard USB hub ports can provide from the typical 500 mA/2.5 W of current, only 100 mA from non-hub ports. USB 3.0 and USB On-The-Go supply 1.8 A/9.0 W (for dedicated battery charging, 1.5 A/7.5 W full bandwidth or 900 mA/4.5 W high bandwidth), while FireWire can in theory supply up to 60 watts of power, although 10 to 20 watts is more typical.
