Cooperating process required an interprocess communication mechanism. This work on which of the following fundamental model.
(A) Shared Memory
(B) Cascading termination
(C) Message passing
(D) Cooperating
Explanation
Solution
Interprocess Communication (IPC) is a mechanism that allows processes to communicate with each other and synchronize their actions. There are two fundamental models of IPC:
1. Shared Memory Model: In this model, a region of memory that is shared by cooperating processes is established. Processes can then exchange information by reading and writing data to the shared region.
2. Message Passing Model: In this model, communication happens by means of messages exchanged between the cooperating processes. It is useful for exchanging smaller amounts of data and is easier to implement in a distributed system.
Analysis of other options:
-
Cascading termination: This refers to the situation where if a parent process terminates, all its children must also be terminated. It is not an IPC model.
-
Cooperating: This is the type of process that needs IPC, not the mechanism itself.
Final Answer:
Both Shared Memory and Message passing are the fundamental models. Therefore, the correct combination is A and C.
The correct option is (a).
