The routing of a signal, data stream, etc. from its origin back to the origin, primarily as a means of testing the transmission or transportation infrastructure
(Bilgisayar) Loopback (loop-back) describes ways of routing electronic signals, digital data streams, or flows of items from their originating facility back to the source without intentional processing or modification. This is primarily a means of testing the transmission or transportation infrastructure
A loopback uses SQL*Net to go from the server right back to itself Performing a successful loopback verifies that SQL*Net works on the server
virtual network interface of a machine with itself, which allows the running programs not to have to take into account the special case where two network entities are in fact the same machine
A diagnostic procedure used for transmission devices A test message is sent to a device being tested The message is then sent back to the originator and compared with the original transmission Loopback testing may be performed with a locally attached device or conducted remotely over a communications circuit
A diagnostic test or test state in which the transmitted signal is returned to the sending device after passing through a communications link or network
A diagnostic test in which a signal is transmitted across a medium while the sending device waits for its return
A diagnostic test that returns the transmitted signal back to the sending device after it has passed through a network or across a particular link The returned signal can then be compared to the transmitted one The discrepancy between the two help to trace the fault When trying to locate a faulty piece of equipment, loopbacks will be repeated, eliminating satisfactory machines until the problem is found
A diagnostic test that returns the transmitted signal to the sending device after the signal has passed through a network or across a particular link The returned signal can then be compared to the transmitted one and the discrepancies between the two can be used to trace the fault When you are trying to locate a faulty piece of equipment, you can repeat loopbacks, eliminating satisfactory machines, until the problem is found
Mechanism that allows you to open a connection to a computer that does not go over the network
A method of checking the accuracy of data transmission in which the transmitted data stream is returned, or looped back, to its source for comparison with the original data Loopbacks can be performed on data in an analog or digital state
Diagnostic test where the transmitted signal is returned to the sending device after passing through a datacomms link or network
This is the process of sending out a test signal to the device on the network so that you know if your signal was successful or unsuccessful
This is a method of testing your equipment Most CODECs have a loopback facility, which takes all the outgoing data from the encoder section and supplies it to the decoder section The upshot is that any audio you send into the CODEC should return on the output of the CODEC There are also telephone numbers that are defined as Loopbacks and these can be used to test not only your CODEC but your terminal adapter and the line itself
Directing signals back toward the transmitting terminal at some point along the communications path Used as a method of troubleshooting
A type of diagnostic test in which a transmitted signal is returned to the sending device after passing through a data communications link or network This test allows the comparison of a returned signal with the transmitted signal
When you test modems, you can ask a remote modem to send back the same test message you send it This is called remote loopback To localize the problem, you might then ask the local modem to echo back to the computer the message sent to it, without sending it out to the remote modem This is called local loopback
Diagnostic procedure used for transmission devices A test message is sent to a device being tested, which is then sent back to the originator and compared with the original transmission Loopback testing may be within a locally attached device or conducted remotely over a communications circuit
A logical interface on a Cisco router that is always "up" and does not connect to anything
