Questions tagged [buffer]

A buffer serves as a designated memory space where data can be temporarily stored during transfer from one location to another. It is commonly used to enhance the efficiency of tasks that involve significant time lags, like sending data to a disk, printer, or any other physical device. By preparing the output for transmission before the receiving device is ready to receive it, the data is preemptively moved to the buffer, streamlining the process and eliminating unnecessary delays for the sending program.
