ABSTRACT:
In a computer system including a main memory and an expanded memory for expanding said main memory logically, a program operating on a virtual memory space, which is managed by the virtual memory management of an operating system, for managing the input/output of the data on an external storage device by using an I/O buffer has a function to manage the I/O buffer secured on the expanded memory, so that the I/O processing for the external storage memory may be reduced by either saving the data, if necessary, of the I/O buffer on the virtual space into the I/O buffer on the expanded memory or restoring the same to the I/O buffer on the virtual space, whereby the I/O buffers can be efficiently utilized.
