What is Forward Error Correction (FEC)?
Q: What is Forward Error Correction (FEC)?
A: Forward Error Correction (FEC) is a special code used in telecommunications for error detection and correction.
Q: How does a sender implement FEC?
A: The sender adds redundancy to parts of the data to implement FEC.
Q: What is the purpose of the redundancy added by the sender in FEC?
A: The purpose of the redundancy added by the sender in FEC is to enable the receiver to detect certain errors that may have occurred during the transfer of the data.
Q: How does the receiver detect and correct certain errors in FEC?
A: The receiver is able to detect and correct certain errors in FEC by using the redundancy added by the sender to the transmitted data.
Q: Is retransmission always necessary in FEC?
A: No, retransmission of data is not always necessary in FEC as the receiver may be able to correct the error using the redundancy added by the sender.
Q: Is FEC used only in specific telecommunication cases?
A: Yes, FEC is used only in certain cases in telecommunications.
Q: What is the benefit of using FEC in telecommunications?
A: The benefit of using FEC in telecommunications is that it enables error detection and correction without the need for retransmission of data, which can save time and resources.
