About this MCQ

This Hard Computer Architecture MCQ checks one syllabus fact.

The question is: “Identify the correct definition of Memory-mapped I/O.”

The accepted answer is C. A method of performing input/output where peripheral devices are accessed using the same address space as memory.. Identify the correct definition of Memory-mapped I O is answered by A method of performing input output where peripheral devices are accessed using the same address space as memory option C Option A The order in which bytes are arranged within larger data types in a computer's memory does not match the stem it is a near-miss used to catch incomplete recall of A method of performing input output where peripheral devices are accessed using the same address space as memory Option B The number of bits a processor can handle or transfer in a single operation does not match the stem it is a near-miss used to catch incomplete recall of A method of performing input output where peripheral.

A. The order in which bytes are arranged within larger data types in a computer's memory.
Why not A: “The order in which bytes are arranged within larger data types in a computer's memory.” is not correct. The accepted answer is C.
