I/O area

A reserved segment of memory used to accept data from an input device or to accumulate data for transfer to an output device. See buffer.



buffer

A reserved segment of memory within a program that is used to hold the data being processed. Buffers are set up to hold data coming in from and going out to the network or a local file. In a streaming media application, the program uses buffers to store an advance supply of audio or video data to compensate for momentary delays.

With computers, each application can allocate and deallocate its buffers from the general memory pool. For printers and other peripherals, the buffers provide temporary storage for data in the memory of the device. See buffering, double buffering, buffer overflow, buffer flush and bucket.
