A temporary storage area, attached to the CPU, for I/O operations, is a Buffer.
In computer science, a data buffer (or just buffer) is a region of a physical memory storage used to temporarily store data while it is being moved from one place to another. ... However, a buffer may be used when moving data between processes within a computer.
A temporary storage area, usually in RAM. The purpose of most buffers is to act as a holding area, enabling the CPU to manipulate data before transferring it to a device.
A Buffer is a data area shared by hardware devices or program processes that operate at different speeds or with different sets of priorities. The Buffer allows each device or process to operate without being held up by the other.
Because the processes of reading and writing data to a disk are relatively slow, many programs keep track of data changes in a buffer and then copy the buffer to a disk. For example, word processors employ a buffer to keep track of changes to files. Then when you save the file, the word processor updates the disk file with the contents of the buffer. This is much more efficient than accessing the file on the disk each time you make a change to the file.
