Hard Real-Time Systems are computing systems that must complete their tasks within strict time constraints. Missing a deadline in these systems can lead to catastrophic failures, especially in critical applications like aviation, medical devices, or automotive safety systems. These systems are designed to ensure that all operations are predictable and reliable. They often use specialized scheduling algorithms to prioritize tasks and manage resources efficiently, ensuring that time-sensitive operations are executed precisely when needed. This reliability is crucial for maintaining safety and performance in environments where timing is critical.
