Interacting Processes in Operating System

In a computer system, interacting processes refer to processes that communicate with each other and share resources. When more than one process works together and needs to coordinate its execution, they are called interacting processes. These processes can exchange data, share their tasks, or use system resources among themselves.

Typically, processes in an operating system are independent. But when two or more processes need to exchange data or messages to complete the same task, they become interacting processes.

1. Message Passing: One process sends a message to another.

2. Shared Memory: Two or more processes share a memory space.

3. Pipes: A technique for sending data from one process to another in one direction.

4. Signals: Small messages sent from one process to another to notify it of an event.

5. Sockets: Used for communication between processes running on the same or different machines.
