Data buffer

A data buffer is a portion of physical memory that temporarily stores data while being moved from one location to another. While all data buffers utilize physical memory, they may be implemented in a fixed location in hardware or use a virtual data buffer through software that points to a physical location.

Commonly used in computing and communication systems, data buffers help components work together and handle tasks at different speeds. Buffers are particularly useful when data is transmitted in small bursts or asynchronously. Essentially, they smooth the data flow and accommodate differences in data transfer rates between a sender and receiver. For example, a data buffer might be a go-between for a slower input/output device (like a printer) and a faster CPU (central processing unit).
