Interprocess communication comes in handy when multiple process try to access a shared resource. A resource can be anything on a machine. It can be memory, a peripheral device etc.
When multiple processes are executing concurrently, they need an awareness so as to complete their task by using a common / shared resource.
Example : There is a camera on your smart phone. This camera cannot be accessed / used by two different apps (or processes) simultaneously. So there should be an awareness mechanism between the apps which tells them when a resource will be free. This is provided by the interprocess communication.
