When interrupts are disabled on most devices, they remain pending until they

When interrupts are disabled on most devices, they remain pending until they can be pro- cessed when interrupts are again enabled. No further interrupts are allowed. The functioning of the devices themselves is temporarily halted. However, in real-time systems, the environ- ment that generated the interrupts is often disassociated from the computer system. When interrupts are disabled on the computer system, the environment keeps on generating inter- rupts anyway. These interrupts can be lost. a Discuss the consequences of lost interrupts. b In a real-time system, is it better to lose occasional interrupts or to halt the system tem- porarily until interrupts are again enabled?
