This document discusses and compares USB hubs and docks. It provides details on three USB hubs: 1) A 4-port USB-C hub from SF Cable for connecting devices to laptops with USB-C ports, 2) A 4-port USB 2.0 hub with connectors for printers, iPods, and USB micro devices, and 3) A 13-port USB 2.0 hub with a power adapter for transferring files between devices at speeds up to 480Mbps. USB hubs expand the number of ports on devices while USB docks can also supply power and support additional peripherals like monitors through a single cable.
