WebShared memory IPC is often preferred when processes need to exchange large amounts of data. Message Passing Another major IPC concept implemented by most popular operating systems is message passing. In message passing, processes exchange data by passing messages using only two operations: send and receive. WebMessage passing is a technique for invoking behavior (i.e., running a program) on a computer. In contrast to the traditional technique of calling a program by name, message passing uses an object model to distinguish the general function from the specific implementations.
