A 2-port network is driven by a source Vs = 100 V in series with 5 ohm, and terminated in a 25 ohm resistor. The impedance parameters are The Thevenin equivalent circuit presented to the 25 ohm resistor is Correct Answer 160 V, 6.8 ohm

100 = 25I1 + 2I2, V2 = 40I1 + 10I2 Also V2 = 160I1 + 6.8I2 using above equations we get, Vth = 160 V and Rth = 6.8 ohm.

You are the administrator of a Windows 2000 Server computer. The server contains one network adapter and is a file and print server for critical company resources. You install a second network adpater in the server and connect it to the same network subnet as the first adapter. You want to ensure that the first adapter is used for all network traffic and the second adapter is used only if the first adapter fails or is disconnected from the network. You also want to ensure that the server always has network connectivity even if one network adapter fails. What should you do?
