What are real-time systems and how does message passing work in them?

Real-time systems are computing systems that must respond to inputs or events within a strict time limit. Message passing is a method used in these systems to enable communication between different processes or threads, ensuring timely data exchange.

Can you give me an example of a real-time system?

Sure! An example of a real-time system is an air traffic control system, which must process and respond to aircraft data in real-time to ensure safety.

What are the advantages of using message passing in real-time systems?

Message passing allows for better modularity and scalability, as well as improved synchronization between processes, which is crucial in real-time applications.

Are there any challenges associated with message passing?

Yes, challenges include managing message delays, ensuring message integrity, and handling the complexity of communication protocols.
