Data buffer
- A region of physical memory storage used to temporarily store data while it is being moved from one place to another, typically in the computer’s memory.
- A buffer may be used when moving data between processes within a computer.
- Buffers can be implemented
- in a fixed memory location in hardware or
- by using a virtual data buffer in software, pointing at a location in the physical memory.
- In all cases, the data stored in a data buffer are stored on a physical storage medium.
- Each application can allocate and deallocate its buffers from the general memory pool.
