He aha ke kamaʻilio inter process ma Unix?
Interprocess communication is the mechanism provided by the operating system that allows processes to communicate with each other. This communication could involve a process letting another process know that some event has occurred or the transferring of data from one process to another.
What is Inter Process Communication IPC )? Explain with figures and example?
Inter process communication (IPC) is used for exchanging data between multiple threads in one or more processes or programs. … It is a set of programming interface which allow a programmer to coordinate activities among various program processes which can run concurrently in an operating system.

What are the two models of IPC What are the strengths and weakness of the two approaches?
Strength:1. Shared memory communication is faster the message passing model when the processes are on the same machine. Weaknesses:1. … Processes that communicate using shared memory need to address problems of memory protection and synchronization.
What is interprocess communication Sanfoundry?
Explanation: Interprocess Communication (IPC) is a communication mechanism that allows processes to communicate with each other and synchronise their actions without using the same address space.

- Create the shared memory segment or use an already created shared memory segment (shmget())
- Attach the process to the already created shared memory segment (shmat())
- Detach the process from the already attached shared memory segment (shmdt())
- Control operations on the shared memory segment (shmctl())
