Which class of computer systems reads input data and is required to react, compute, and respond within strict real-world clock time constraints?
Multiple Choice Options
- A
Batch processing system
- B
Quick response system
- C✓ Correct Option
Real-time system
- D
Time-sharing system
Detailed Technical Solution & Explanation
A Real-Time System (RTS) is a computing system whose correctness depends not only on the logical correctness of the computational result, but also on the time at which the result is produced. If timing constraints (deadlines) are violated, system degradation or catastrophic failure occurs (in hard real-time systems like automotive ABS, flight avionics, and medical pacemakers).
Option Analysis:
•
Option A (Batch processing system): Jobs are queued and processed sequentially without interactive timing deadlines.
•
Option B (Quick response system): Vague colloquial description, not a formal computing system taxonomy.
•
Option C (Real-time system): Correct; explicitly bound by deterministic real-world time constraints.
•
Option D (Time-sharing system): Shares CPU slices among interactive multi-users with best-effort response times.
