Waves of Faults in Embedded System and Way out through Fault Tolerance

Software has rapidly become an important and indispensable element in many aspects of our daily lives. If such element is not running as on our need, we have to go through the problems about it. In initially, the paper focus on the different types of faults, their impact and fault classification. Faults are subdivided into different activities such as fault prediction, fault detection, fault prevention, fault correction etc. Here we study the faults in context boiler system. The concern thing is Faults classification as external, location, duration, and effect, permanent, temporary and may more. Any fault arise within system can be avoid, prevent or removed. Then we propose the different fault tolerance techniques to deal with different faults.
