Introduction
Message passing is a communication mechanism that allows processes to exchange data and communicate with each other. It is a method of interprocess communication (IPC) where processes can send and receive messages.
Explanation
Option A: Communicate with each other without sharing the same address space- In a message passing system, processes can communicate with each other without the need to share the same address space.
- Address space refers to the memory space allocated to a process, which contains its code, data, and stack.
- In other words, processes in a message passing system may not be running on the same machine or have direct access to each other's memory.
Option B: Communicate with one another by resorting to shared data- This option is incorrect because message passing does not rely on shared data.
- Shared data refers to a data segment that is accessible by multiple processes, allowing them to read and write data.
- Message passing, on the other hand, involves sending and receiving messages between processes without directly accessing shared data.
Option C: Share data- This option is incorrect because message passing does not involve sharing data between processes.
- Instead, it focuses on exchanging messages, which can contain information or instructions.
Option D: Name the recipient or sender of the message- This option is incorrect because message passing does not necessarily require naming the recipient or sender of the message.
- In some message passing systems, processes may communicate anonymously, without explicitly identifying the sender or receiver.
Conclusion
The correct option is A: Communicate with each other without sharing the same address space. Message passing allows processes to communicate by sending and receiving messages, without the need for shared data or explicitly naming the sender or receiver. It enables interprocess communication even when processes are running on different machines or have separate memory spaces.
