What is the default I/O range for COM2?

  1. 2F8-2FF

  2. 3F8-3FF

  3. 378-37F

  4. 220-22F

The correct answer is: 2F8-2FF

The default I/O range for COM2 is 2F8-2FF. This range is used for the serial port COM2 and is used for data communication between a computer and external devices. Option B (3F8-3FF) is the default I/O range for COM1, so it is incorrect. Option C (378-37F) and D (220-22F) are default I/O ranges for other hardware devices and are not used for COM2, making them incorrect options as well.
