Determining the Buffering Method for an I/O Operation

Web1 mrt. 2024 · Single I/O Buffer The simplest form of buffering is using a single buffer implementation. As a user process executes, it issues an I/O request, This causes the OS to assign a buffer in the system portion of main memory to the I/O operation. The OS then send the request to the proper device. WebThe goal of the buffering provided by the standard I/O library is to use the minimum number of read and write calls. (Recall Figure 3.5, where we showed the amount of CPU time required to perform I/O using various buffer sizes.)
