A computer the size of a USB drive that plugs into the HDMI port of a TV for display. Also called a "screenless PC," "any screen computer," or "PC on a stick," it either uses an ARM or Atom CPU and runs a version of Linux or Windows. Storage is flash memory. Interaction with the computer is via a smartphone or tablet, wireless keyboard and mouse or infrared remote control.
