USB Hubs
A USB hub takes one USB port and splits it into multiple ports.

Answers
Frequently asked questions
Can a USB hub output to a monitor?
Standard USB hubs cannot output video. A USB-C hub with DisplayPort Alt Mode or an HDMI adapter can output video, but only when the USB-C port on the computer supports video output, not all USB-C ports do. A dedicated USB-C dock provides more reliable video output with dedicated bandwidth.
Is a USB-C hub the same as a USB-C dock?
A USB-C hub is compact, bus-powered, and connects via a short cable or direct plug-in. A USB-C dock is larger, usually desk-mounted, powered by its own adapter, and provides higher bandwidth for video, ethernet, and charging simultaneously. Docks cost more and support heavier workloads.
Do USB hubs reduce speed?
A USB 3.0 hub shares 5Gbps between all its ports when multiple devices are in use. If only one high-bandwidth device is connected, it gets the full 5Gbps. When two external SSDs transfer simultaneously through a USB 3.0 hub, each gets roughly 2.5Gbps. USB 2.0 hubs are capped at 480Mbps total, not suitable for external storage.
