A USB hub is a accessory that expands a individual USB anchorage into several so that there are added ports accessible to affix accessories to a host system.
USB hubs are generally congenital into accessories such as computers, keyboards, monitors, or printers. When such a accessory has abounding USB ports they all usually axis from one or two centralized USB hubs rather than anniversary anchorage accepting absolute USB circuitry.
Physically abstracted USB hubs appear in a advanced array of anatomy factors: from alien boxes (looking agnate to a arrangement hub) connectible with a continued cable, to baby designs that can be anon acquainted into a USB anchorage (see the 'compact design' picture). In the average case, there are "short cable" hubs which about use an basic 6 inch cable to hardly ambit a baby hub abroad from concrete anchorage bottleneck and of advance access the amount of accessible ports.
Laptop computers may be able with abounding USB ports, but an alien USB hub can consolidate several accustomed accessories (like a abrasion and a printer) into a individual hub to accredit one-step adapter and abatement of all the devices.
