378H
278H
3f8h
2e8h E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is C. 3f8h.
LPT2 is the second parallel port on a computer. It is typically used to connect a printer. The I/O port for LPT2 is 3f8h. This means that when the computer sends a signal to the LPT2 port, it is sending it to the address 3f8h.
The other options are incorrect. Option A, 378h, is the I/O port for LPT1. Option B, 278h, is the I/O port for the serial port COM1. Option D, 2e8h, is not a valid I/O port.
I hope this helps!
