A region of memory reserved for use as an intermediate repository in which data is temporarily held while waiting to be transferred between two locations or devices. For instance, a buffer is used while transferring data from an application, such as a word processor, to an input/output device, such as a printer.
In computing, a part of the memory used to store data temporarily while it is waiting to be used. For example, a program might store data in a printer buffer until the printer is ready to print it.(Computer science) A part of RAM used for temporary storage of data that is waiting to be sent to a device; used to compensate for differences in the rate of flow of data between components of a computer system; SYN. buffer storage.
A storage area for data that is used to compensate for a speed difference, when transferring data from one device to another. Usually refers to an area reserved for I/O operations, into which data is read, or from which data is written.

A small amount of system memory that stores the most recently typed characters. This buffer is used to store typed characters that have not yet been processed. Also called: type-ahead buffer.
A buffer that keeps track of key strokes until the computer is ready to respond to them.

A section of memory to which print output can be sent for temporary storage until the printer is ready to handle it. A print buffer can exist in a computer’s random access memory (RAM), in the printer, in a separate unit between the computer and the printer, or on disk. Regardless of its location, the function of a print buffer is to free the computer for other tasks by taking print output at high speed from the computer and passing it along at the much slower rate required by the printer. Print buffers vary in sophistication: some simply hold the next few characters to be printed, and others can queue, reprint, or delete documents sent for printing.
A buffer that stores data until the printer is ready.

1. The use of a special area in memory to hold data temporarily for processing until a program or operating system is ready to deal with it.
2. An area of storage that is used to hold data to be passed between devices that are not synchronized or have different bit transfer rates.
