Real-time systems are computer systems that must process data and provide responses within a strict time limit. These systems are crucial in applications where timing is critical, such as in medical devices, automotive safety systems, and industrial automation. If they fail to respond on time, it can lead to serious consequences, such as accidents or system failures. There are two main types of real-time systems: hard real-time systems and soft real-time systems. Hard real-time systems require absolute adherence to deadlines, while soft real-time systems can tolerate some delays without catastrophic results. Understanding these systems is essential for designing reliable technology in various fields.
