Break Down the Problem

1. Identify the key concepts related to thread priority.
2. Determine the correct role responsible for deciding thread priority from the given options.

Relevant Concepts

• Thread Priority: This refers to the importance given to a thread by the operating system. Threads with higher priority are executed before those with lower priority.
• Schedulers:
  • Thread Scheduler: Manages the execution of threads, deciding which thread runs at any given time.
  • Process Scheduler: Manages the execution of processes, determining which to run based on their overall needs and priorities.

Analysis and Detail

1. We know that the thread scheduler specifically works with threads, making decisions based on their priorities.
2. The process scheduler, on the other hand, deals with overall processes, which may contain multiple threads.

Verify and Summarize

• The thread scheduler is directly responsible for managing thread priorities, therefore the option that answers the question correctly is "Thread Scheduler".

Final Answer

Thread Scheduler is the correct answer; it decides thread priority.
