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) In electronics, a circuit is a path between two or more points along which an electrical current can be carried.A circuit breaker is a device that interrupts the path when necessary to protect other devices attached to the circuit-for example, in case of a power surge.). 2) In telecommunications, a circuit is a discrete (specific) path between two or more points along which signal s can be carried.
