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.
fuse. Noun. A safety device that protects an electric circuit from becoming overloaded. Fuses contain a length of thin wire that melts and breaks the circuit if too much current flows through it. Fuses have largely been replaced by circuit breakers. Verb. 1. To melt something, such as metal or glass, by heating. 2. To blend two or more substances by melting: Bronze is made by fusing copper and tin.
