Show answer & explanation
Correct answer: C
Correct matching: (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)
Isolated I/O: uses separate I/O instructions distinct from memory access instructions, so it matches 'separate instructions for I/O and memory communication'.
Memory-mapped I/O: places devices in the processor's address space and uses the same control/addressing mechanisms as memory, so it matches 'same set of control signal for I/O and memory communication'.
I/O interface: resolves differences in voltage levels, timing, and protocols between the central computer and peripherals, so it matches 'resolve the differences in central computer and peripherals'.
Asynchronous data transfer: uses handshaking control signals exchanged between the communicating units to coordinate transfers, so it matches 'requires control signals to be transmitted between the communicating units'.
