What is the Exact function of loop back addressWhich is loop back add127.0.0.0 or 127.1.1.1?
The loopback address is 127.0.0.1. It is also called 'localhost'. It's purpose is simple: It's the most rudimentary test for functionality of your NIC (Network Interface Card). For example, if you ping 127.0.0.1 OR ping localhost you'll get a response IF your NIC is enabled, connected to something (physical network or wireless) and working. Problems with localhost pinging usually means a problem with the NIC itself. Google Web Accelerator, Hello, and some other tools take advantage of the loopback address for functionality. They open a port on loopback to internally 'host' web pages. Google Web Accelerator for example, creates a local cache of your web pages, and sets your proxy to the loopback address on a specific port, so that you get the local cache first, giving the illusion of instantaneous loading of the page.
How do you have the tunnel interface and the IPv6 Loopback interface as the only connections running IPv6?
by unchecking the check box of IPv6 in local area network properties
What is a digital local loop?
A local digital loopback is a test that is performed to check the transmitter and receiver of a local modem, or being simpler, it's a test that sends a signal to a remote receiver and waits for the signal to be returned.
What is the difference between a null and loop-back interface?
Loop, is a word. We could say that the Earth loops the sun. Because the Earth in his orbit, has always the same path, so is going nowhere, its looping and never stop. Around and around, year by year. Looping the sun. A loopback, is back, because someone is checking it. Back in his office or node or house. Testing it, and checking if the loop is good or not. For example: God was checking the universe, and say: lets loop all planets to the sun. Set loopback to earth at 395 days, set loopback to Pluton to... etc. As he is checking it, testing it, creating it, etc... its making a loopback. Null, is a logically concept. As a loop or loopback could be theorical, logical, or physical (mathematics, hardware, or software) null is always logical. Null is like a void, a dead end, a trash without recovery. All that is dropped there, you never see it again. The way more easly to undertand, is that in maths, null is the same to say zero: 0. In computers a null interface, device, cable, etc... is going to nowhere. And all to a null int. will be losted. Equal if we want it to multiply some number by zero (null). 43213421145678765432 x 0 = 0. That means that no matter what is the number, the amount, or the data... it wont exist at the end. If i say that tomorrow i will be driving on the null freeway, that is suicide. If i say that now im playing revolver null Russian roullete... means that my gun doesnt have any ammo. XD. Have a nice day ! :D LM.

What tool can help you find out which wall jack connects to which port on a switch in an electrical closet?
A loopback plug
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
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 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

What are the difference between local loop back testing and remote loop back testing?
The only difference is the relative location of the device that is in loopback mode. Local loopback testing is when your device is set to send back everything it receives to the sender, aka loopback mode. Remote loopback testing is when your device orders a foreign device to enter loopback mode.
What are the difference between rollpack and loopback?
Rollback is a feature in database management that allows reverting changes back to a previous state if needed, while loopback is a type of network configuration where data sent out to a network is looped back to the sender without leaving the local system. These terms are used in different contexts and serve different purposes in computer science and networking.
