What is the interface circuit?(a) Helps in installing of the software

1.	What is the interface circuit?(a) Helps in installing of the software driver for the device(b) Houses the buffer that helps in data transfer(c) Helps in the decoding of the address on the address BUs(d) None of the mentionedThis question was addressed to me in class test.My question is taken from Interface Circuits in division Input/Output Organisation of Computer Architecture
Answer» The CORRECT answer is (c) Helps in the decoding of the address on the address BUS To elaborate: Once the address is put on the BUS the interface circuit decodes the address and USES the buffer SPACE to transfer data.
