3. 3. Shared memory and message passing model
4. 4. Queues

Answer : 3. Shared memory and message passing model

2. Co-operating process: It can be affected by other executing processes.

Interprocess communication (IPC) method which will allow them to exchange data along with various information among co-operative processes.
