This same principle of amplification is employed in real-time PCR. But instead of looking at bands on a gel at the end of the reaction, the process is monitored in “real-time”. In real time, time is critical and delays can be catastrophic but in real-time transactions systems there is no time criticality. E.g. poor speeds in airline control would be dangerous but poor booking speeds would not be so crucial.

A missed deadline in hard real-time systems is catastrophic and in soft real-time systems it can lead to a significant loss. Hence predictability of the system behavior is the most important concern in these systems. Predictability is often achieved by either static or dynamic scheduling of real-time tasks to meet their deadlines. Static scheduling makes scheduling decisions at compile time Applications of embedded systems are applicable in areas like space, communication, transportation, robotic systems, home appliances, etc. This article is intended to give information about the embedded system applications.
