a router configured to half duplex connected to a swich connected to full duplex what will be the resulting communication mode,HALF OR FULL DUPLEX?why?
what i mean i need clarification of a resulting communication mode when two or more devices of different configurations are connected?

When two or more devices are connected the resulting service is what the lowest device produces. You can't force the slowest or lowest device to perform faster by connecting it to faster devices. So with your example you would get half-duplex because that's what the switch would be recieving and it doesn't have the capacity to turn it into full duplex even though there is a setting for full duplex.

Meaning that half duplex can only send transmission in one direction at time, whereas full duplex can send both ways simultaneously. So, the limitation would be a result of the half duplex configured router, thus limiting the full duplex router to half of its configured operating speed, and the network between the two routers operating at half duplex.
