In real-time systems, the effectiveness and reliability of operations are critical. These systems are designed to process and respond to events instantly, ensuring that actions are executed within defined time limits. 

To achieve this goal, specific design and development techniques are employed, such as resource allocation based on task priority, optimizing execution times, and using real-time control algorithms. 

Additionally, continuity and error tolerance are often integrated into systems to ensure the continuity of operations even in the presence of hardware or software failures. Real-time systems find applications in a variety of sectors, including industrial automation, traffic control, air navigation, and robotics, where speed and accuracy of response are crucial for operational success.
