A stick PC or PC on a stick is a single-board computer in a small elongated casing resembling a stick, that can usually be plugged directly (without an HDMI cable) into an HDMI video port. A stick PC is a device which has independent CPUs or processing chips and which does not rely on another computer. It should not be confused with passive storage devices such as thumb drives.
A stick PC can be connected to a peripheral device such as a monitor, TV, or kiosk display to produce visual or audio output. Stick PCs generally have limited computing power and are not suited for intensive tasks, but can be suitable in other applications that do not require such power.
