What is the MIDI/Joystick port's characteristic feature?

  1. 3 rows of pins

  2. 2 rows of pins

  3. Circular connector

  4. Single row of pins

The correct answer is: 2 rows of pins

The characteristic feature of MIDI/Joystick port is that it has two rows of pins. This allows for data to be transmitted in both directions between a device and a computer. Option A is incorrect because there are not three rows of pins, which is the case with other types of ports such as a parallel port or VGA port. Option C is incorrect because a circular connector is not a defining feature of a MIDI/Joystick port, as other ports such as a PS/2 port also have circular connectors. Option D is incorrect because a single row of pins would not allow for data to be transmitted both ways, which is necessary for joysticks and MIDI devices.
