Time-shared OS-এর জন্য কোন Scheduling policy সবচেয়ে ভালো?
- A) First come first serve
- B) Round-robin
- C) Shortest job first
- D) Last come first serve
Show answer
Answer: B) Round-robin
Explanation
Round-robin is best for time-sharing. Each process gets a short fixed time slice in turn, so many users sharing one machine all see quick responses. First come first serve lets one long job block everyone, and shortest job first can make long jobs wait indefinitely.
