Serial Port
Serial PortA
Serial Port is a piece of hardware that is used to transfer information between two devices using serial communication. A typical serial port interface is a 9 pin D-sub connector, but can come in many different types of form-factors.
USB is also a type of serial port and stands for Universal Serial Bus. USB is a much more complicated standard than the typical 9-pin D-sub serial port you might find on a desktop computer (RS-232 standard). Anyway you look at it, most data transmission between different devices is sent serially and most robots utilize some form of serial communication. An example is the SCI communication port on the roomba.
