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.
The crudest type of circuit breaker is the fuse. Most would consider that a fuse is different than a circuit breaker. That may be true, but technically, fuse qualifies as circuit breaker because it does just that ââ it breaks a circuit. Fuses are still in use today but are gradually getting obsolete.
