A p- channel enhancement type MOSFET performs much the same function as a PNP transistor, except that
Options: it operates much faster, it is considerably larger, it is controlled by voltage rather than by current, so that it requires very little current at the control terminal, it is controlled by current rather than by voltage like a bipolar transistor.
Options: It sends back the protocol received from a router as a poison pill, which stops the regular updates., It is information received from a router that can't be sent back to the originating router., It prevents regular update messages from reinstating a route that has just come up., It describes when a router sets the metric for a downed link to infinity.
