Why is a buffer used during input and output operations?

Answer and explanation

Correct answer: To temporarily hold data between components operating at different speeds

A buffer is a temporary memory area that manages the difference in data-transfer speeds between components. For example, rapidly arriving input data can be held in a buffer until the processor or output device is ready to process it. Option B describes permanent storage, whereas a buffer is temporary. Exam tip: remember a buffer as ‘temporary storage for handling a speed mismatch.’
