A buffer is a temporary storage area specifically designed to compensate for speed differences between system components that process data at different rates. It holds data when the producing device works faster than the consuming device, preventing data loss. Memory is general storage, an accumulator is for arithmetic operations, and address is a location identifier - none of these specifically handle speed mismatch.
