What is cascading termination?

- If one process is terminated, its related processes are also terminated abnormally then it is called cascade termination.

- It occurs in the case of parent child process.

- If the parent process is terminated normally or abnormally then all its child processes must beterminated.

- The parent is existing and the operating system does not allow a child to continue if its parent terminates.

- This child process is the new process created by the process called the parent process.

Explain IPC.

- It is called as the inter process communication.

- The scheme requires that processes share a common buffer pool and code for implementing the buffer.

- It allows processes to communicate and to synchronize their actions.

- Example : chat program used on the world wide web.

- It is useful in distributed computer systems where communicating processes reside on different computers connected with a network.
