Which of the following operations on context-free languages does NOT always produce a context-free language?
- A. Union of two context-free languages
- B. Concatenation of two context-free languages
- C. Intersection of two context-free languages
- D. Kleene star of a context-free language
Answer: C. Intersection of two context-free languages
Context-free languages are closed under union, concatenation, and Kleene star. However, they are NOT closed under intersection. A classic example: L1 = {a^n b^n c^m} and L2 = {a^m b^n c^n} are both context-free, but L1 ∩ L2 = {a^n b^n c^n} is not context-free.
In the Chomsky hierarchy, which type of grammar generates context-free languages?
- A. Type 0
- B. Type 1
- C. Type 2
- D. Type 3
Answer: C. Type 2
The Chomsky hierarchy classifies grammars into four types: Type 0 (unrestricted/recursively enumerable), Type 1 (context-sensitive), Type 2 (context-free), and Type 3 (regular). Context-free grammars (Type 2) have rules of the form A → α where A is a single non-terminal.
What is the difference between preemptive and non-preemptive scheduling?
- A. Preemptive scheduling does not use a timer; non-preemptive scheduling does
- B. In preemptive scheduling, a running process can be interrupted and moved to ready state; in non-preemptive, a process runs until it voluntarily yields or completes
- C. Non-preemptive scheduling is always faster than preemptive scheduling
- D. Preemptive scheduling only works with single-core processors
Answer: B. In preemptive scheduling, a running process can be interrupted and moved to ready state; in non-preemptive, a process runs until it voluntarily yields or completes
In preemptive scheduling, the OS can forcibly interrupt a running process (e.g., when a higher-priority process arrives or a time quantum expires) and place it back in the ready queue. In non-preemptive scheduling, a process keeps the CPU until it terminates or voluntarily enters a waiting state.
A pipe fills a tank in 10 hours and another empties it in 15 hours. If both are open simultaneously, in how many hours will the tank be filled?
- A. 20
- B. 25
- C. 30
- D. 35
Answer: C. 30
Net rate = 1/10 − 1/15 = 1/30, so the tank fills in 30 hours.
