What is firm real time?

Firm real-time refers to a computing or control system's ability to guarantee that critical tasks are completed within a specified deadline. In a firm real-time system, missing a deadline does not result in catastrophic failure, but it may lead to degraded performance or loss of quality. This contrasts with hard real-time systems, where deadlines must be strictly met, and soft real-time systems, where deadlines are flexible and can be missed without serious consequences. Firm real-time systems are commonly used in applications like multimedia processing and some industrial controls.
