What is a real-time system?

• A real-time system processes data without noticeable delay and responds within a specified time frame.

• A real-time system is same as an embedded system.

• A real-time system has no time constraints for processing data.

• A real-time system operates only in offline mode.

What are the key characteristics of real-time systems?

• Having loose timing constraints

• Not requiring specialized hardware or software

• Meeting strict timing constraints, providing timely responses, being predictable and reliable, often requiring specialized hardware or software

• Being unpredictable and unreliable

Explain the difference between hard real-time and soft real-time systems.

• Soft real-time systems are more reliable than hard real-time systems.

• In hard real-time systems, missing a deadline can lead to system failure, while in soft real-time systems, occasional deadline misses are acceptable.

• Hard real-time systems are more flexible than soft real-time systems.

• In hard real-time systems, deadline misses are acceptable, while in soft real-time systems, missing a deadline leads to system failure.

What is a deadline in real-time systems?

• A deadline in real-time systems is a specific point in time by which a task must be completed to ensure the system functions correctly and meets its timing requirements.

• A deadline in real-time systems is a flexible timeframe that can be adjusted as needed.

• A deadline in real-time systems is a general guideline but not critical for system operation.

• A deadline in real-time systems is a specific point in time by which a task can be delayed indefinitely.

What is the role of a scheduler in real-time systems?

• Coordinates communication between devices

• Manages resource allocation and task prioritization based on deadlines and importance.

• Manages user authentication and access control

• Monitors system performance and generates reports

What are the different types of real-time operating systems?

• Real-time systems, Virtual real-time systems, Embedded real-time systems

• Hard real-time systems, Soft real-time systems, Firm real-time systems

"Patient monitoring system" is an example of

• Hard real time system

• Soft real time system
