In many real-time applications, timing requirements are as important as any other requirements. Consider a medical device controlled by software that is designed to deliver a specific dosage of radiation. If the device delivers the correct amount of radiation, but for too long a time period, it is dangerous. The length of time over which the patient is irradiated is just as important as the level of radiation emitted by the device. These systems are known as hard real-time systems in that they have definite (hard) timing deadlines.

在许多实时应用中，时序要求与其他要求一样重要。考虑一个由软件控制的医疗设备，该设备旨在提供特定剂量的辐射。如果设备提供了正确的辐射量，但时间太长，这是危险的。患者接受辐射的时间长度与器械发出的辐射水平同样重要。这些系统被称为硬实时系统，因为它们有明确的（硬）时间期限。
