When a system is producing output, it is inefficient to send each particle of output individually to its final destination. It is more efficient to gather a meaningful amount of output in a buffer, and then send that output as a batch to its final destination. The buffer ensures that the system receiving the output does not receive a continual barrage of little updates. With a buffer, the receiver can receive the output in larger, more manageable chunks.

If you go on holiday, and pack each item of clothing in the car, then drive the car to the destination, and then return for the next item of clothing, you will observe that it is an inefficient approach. Instead of transporting your items of clothing individually to their destination, the convention is to pack them in a buffer (a suitcase) and then to transport the entire buffer to the destination in a single operation.
