Show answer & explanation
Correct answer: B
In operating systems, a buffer is a region of memory used for temporary data storage, not merely a special register. Buffering primarily addresses speed mismatches between data producers and consumers, such as the CPU and I/O devices. Since statement (i) is incorrect and statement (ii) is accurate, the correct choice identifies only statement (ii) as true.
