CUET PG 2021 — Computer PYQ
CUET PG | Computer | 2021A CPU –bound program might have
Choose the correct answer:
- A.
a few long CPU bursts
(Correct Answer) - B.
a few short CPU bursts
- C.
many short CPU bursts
- D.
None of the above
a few long CPU bursts
Explanation
1. Time Equation:
Total execution time (Ttotal) ke do hisse hote hain: CPU time (Tcpu) aur I/O time (Tio). CPU-bound program ke liye:
Yahan CPU ka waqt I/O ke waqt se bahut zyada hota hai.
2. Characteristic Equation:
Aise programs mein lambe CPU bursts hote hain aur bahut kam I/O bursts hote hain.
Solving: Main Features
Ek CPU-bound program mein niche di gayi cheezein ho sakti hain:
-
Long CPU Bursts: Program lagatar calculation karta hai bina ruke.
-
Low I/O Frequency: Input/Output operations bahut kam hote hain.
-
High CPU Utilization: CPU hamesha busy rehta hai (100% utilization ke karib).
-
Scheduling: Aise programs ke liye Preemptive Scheduling (jaise Round Robin) zaroori hoti hai taaki doosre processes "starve" na karein.
Final Answer
Ek CPU-bound program mein "Long CPU bursts" aur "Very few I/O operations" hote hain.
