output cause the parallel port is outside the computer
A USB port is both an input and an output.
output
No. VGA port is not either serial or parallel port. It is a different interface. If you need a serial output, you need a VGA to serial converter.
input
output
output
usually sensor or digitized voltages on the inputs. if the port is parallel port, the input doesn't have to be serialized first. Output ports usually converted back to analog for some control application via D/A converters
Input port
wafi gila
A serial port is neither strictly an input device nor an output device; rather, it is a communication interface that can handle both input and output data. It allows for the transmission of data between a computer and peripheral devices, such as modems or printers. Depending on the direction of data flow, a serial port can function as an input, output, or both simultaneously.
A USB port is both and input and output port. Depends on what is connected to it as to which is functions as. Connect a camera and it is an input device. Connect a printer and it is an output device. Connect a printer/scanner and it is both.
It's an output. I think. The usb port is already in there, so it should be an output. An input is something you put in, and an output is something that comes out. Hope this helps. :)
