What is a hardware loopback adapter?
Something you plug into a port/ slot on a computer that tells it there is a network/connection active on the port but, it is just a facade created by the loopback adapter, you see them a lot in IT technicians tool bags
What command will allow a technician to test a network card?
Loopback plug
Under what circumstance might you use a loopback plug?
to test a network cable
What tool can help you find out which wall jack connects to which port on a switch in an electrical closet?
A loopback plug
Which tool can help you find out which wall jack connects to which port on a switch in a electrical closet?
A loopback plug
Which tool should you use to test the serial port?
You would use a Loopback Plug, this allow an output signal to be returned as input.
What is external hardware?
External hardware is hardware that is connected externally to a computer using its peripheral ports. Examples are VDU, keyboards and mice.
Can port allow you to plug hardware into your CPU?
A port allows you to plug hardware into your CPU.
What are loop-back plugs?
Exact definition of loop-back plugs will depend on what application we are talking about. Mostly these are connector plugs with a metal inside to short two electrical signals. There can be loopback plugs for different applications. These can be for a serial port or an Ethernet port or loopback plugs for specific signals on a connector or on a printed circuit board. These are very useful for debugging and testing an electronics problem. E.g. one can do a loopback on PC serial port's Transmit and Receive (Tx and Rx) lines using a loopback plug or a metal short to see if the serial port is working fine. Similarly Ethernet ports can be tested with a loop-back plug made for the purpose. - Neeraj Sharma

Why does 1994 chev pickup backfires?
Spark Plug wires connected incorrectly, or engine is out of time.Spark Plug wires connected incorrectly, or engine is out of time.
It is best to perform connectivity tests on a computer connected to a live network?
No. Connectivity test does not require a live network. It does however, require a loopback adapter/plug. If you're using the same book (Network+ Guide to Networks 5th Edition by Tamera Dean). You should find your answer on the bottom of page 254. :p
