Multiple choice

The CPU of a computer transfers print output to a temporary disk memory at high speed and get back to processing another job without waiting for the output to go to the printer. In this way, the CPU does not remain idle due to its own high speed as compared to the low speed of the printer. What is the name of this memory?

  1. External Memory

  2. I/O Memory

  3. ROM

  4. Buffer Memory

D Correct answer
Explanation

Buffer memory temporarily stores data being transferred between devices of different speeds. The CPU quickly sends print output to the buffer, then immediately continues processing other tasks while the buffer slowly feeds data to the printer. This prevents CPU idle time.
