The operating system is not responsible for:
Show Hint
- process and thread management.
- the creation and deletion of both; the user and system processes.
- the development of the program.
- the process scheduling.
The Correct Option is C
Solution and Explanation
Step 1: Understand Operating System responsibilities.
The operating system is responsible for managing processes, threads, scheduling, and memory. It provides services such as process creation, deletion, scheduling, and resource management.
Step 2: Evaluate the options.
- **Option 1:** The operating system manages processes and threads.
- **Option 2:** The operating system handles the creation and deletion of processes.
- **Option 3:** The operating system does not develop user programs; it only manages execution.
- **Option 4:** The operating system is responsible for scheduling processes.
Step 3: Conclusion.
Thus, the correct answer is **(3) the development of the program** because the operating system does not create or develop programs, it only manages their execution.

- For a Non-deterministic Finite Automaton (NDFA) with \( N \) number of states, the equivalent Deterministic Finite Automaton (DFA) has \( D \) number of states. Then, possible number of states in DFA can be defined as:
Suppose \( D_1 = (S_1, \Sigma, q_1, F_1, \delta_1) \) and \( D_2 = (S_2, \Sigma, q_2, F_2, \delta_2) \) are finite automata accepting languages \( L_1 \) and \( L_2 \), respectively. Then, which of the following languages will also be accepted by the finite automata:
(A) \( L_1 \cup L_2 \)

Top CUET PG Process Creation and Management Questions
- Process control block in operating system is defined as:
- In the context of process creation, arrange the following statements in sequential order of their occurrence: A. One of the two processes typically uses the exec() system call to replace the process's memory space with a new program.
B. A new process is created by the fork() system call.
C. The parent can then create more children; or, can issue a wait() system call to move itself off the ready queue.
D. The exec() system call loads a binary file into memory (destroying the memory image of the program containing the exec() system call) and starts its execution.
