Performance of microkernel vs monolithic kernel. As is always the answer (or at least the preface) to performance-related questions: know your problem domain, run comparative benchmarks, and remember what premature optimization is.
A summary of the difference between contactors, motor starters, relays and circuit breakers. Switches, circuit breakers, and contactors are used to control what parts of an electrical system are energized or de-energized. Fuses are used to protect the electrical system when something goes wrong, and can isolate the faulted parts from the normal parts.
1 A circuit breaker is a switch. 2  It performs the same function as a fuse, although a circuit breaker can be reset. 3  When the circuit breaker is thrown, the circuit is disconnected from the power source. 4  An isolator is a component that allows AC signals to pass, but stops DC signals.
