Question

_____________ is a mode of communication in which packets of information in predefined format are moved between processes by Operating System.

BlackTom AI · Accepted Answer

Message Passing is a mode of communication in which packets of information in a predefined format are moved between processes by the Operating System.

1. Relevant knowledge points and concepts
- Interprocess Communication (IPC): mechanisms that allow processes to exchange data or synchronize.
- Two primary IPC paradigms: message passing and shared memory.
- Message passing: the OS (or kernel) mediates transfer of discrete messages (packets) between processes using primitives like send/receive, ports, mailboxes, pipes, or sockets. Messages follow a predefined format and may be synchronous or asynchronous.
- Shared memory: processes map the same memory region and read/write directly; the OS establishes the mapping but does not move packets between processes.
- System calls: interface for processes to request OS services; not itself a communication paradigm.
- Phishing: a cybersecurity social-engineering attack, unrelated to IPC.

2. Step-by-step reasoning
- The question specifies "packets of information in predefined format are moved between processes by Operating System." That description matches an IPC method where messages (packets) are explicitly transferred.
- Message passing involves the OS moving or copying message packets from sender to receiver, enforcing the message format and delivery semantics.
- In contrast, shared memory does not involve moving packets: the OS sets up a common address space, and processes access the same memory directly; the data is not packaged and transferred by the OS.
- System calls are the mechanism to request actions (including IPC) but are not the communication mode themselves.
- Phishing is irrelevant.

3. Intermediate steps/calculations
- No numerical calculations are required. The logical mapping is: "packets moved between processes by OS" → message passing.

4. Why the correct answer is correct
- Message Passing explicitly describes moving formatted messages (packets) between processes under OS control, matching the phrase in the question.

5. Why other options are incorrect
- Shared memory: OS does not move packets; processes share memory and access data directly.
- System Call: a mechanism to invoke kernel services, not a form of IPC that packages and moves messages between processes.
- Phishing: unrelated security concept, not an IPC method.

6. Conclusion
The correct answer is Message Passing, which matches the provided answer.
