Processes on the remote systems are identified by . . . . . . . .

Solution (By Examveda Team)

Option A: Host ID typically refers to a unique identifier for a host machine within a network. While it can help distinguish one machine from another, it does not specifically identify processes running on those systems, making this option inadequate.

Option B: Host name and identifier combines both the name of the host and an additional identifier. Although it provides a way to locate a host, it does not directly relate to identifying specific processes running on the remote systems, thus making it less precise.

Option C: Identifier is a general term that could refer to various types of identifiers, but it lacks specificity. It does not clarify what kind of identifier is being used to identify processes on remote systems, making this option vague.

Option D: Process ID (PID) is a unique number assigned by the operating system to each running process. It specifically identifies processes on the system, whether local or remote, making this option the most accurate in the context of identifying processes.

Conclusion: The correct answer is Option D: Process ID, as it accurately represents how processes on remote systems are identified. Process IDs are essential for managing and monitoring processes effectively, making them the most relevant choice in this context.
