What are real-time systems and how do they achieve synchronization?

Real-time systems are computing systems that must respond to inputs or events within a strict time constraint. Synchronization in these systems ensures that tasks are executed in a timely manner, often using techniques like priority scheduling and clock synchronization.

Can you explain the difference between hard and soft real-time systems?

Sure! Hard real-time systems require strict adherence to deadlines, meaning missing a deadline can lead to catastrophic failures. Soft real-time systems, on the other hand, can tolerate some deadline misses without severe consequences, focusing more on overall performance.

What are some common applications of real-time systems?

Common applications include embedded systems in automotive controls, medical devices, telecommunications, and industrial automation, where timely responses are critical.

How do real-time operating systems differ from general-purpose operating systems?

Real-time operating systems (RTOS) are designed to process data as it comes in, typically with minimal delay, while general-purpose operating systems prioritize overall throughput and user experience.
