Applications that require low latency (such as telephone conversations) cannot use automatic repeat request (ARQ); they must use forward error correction (FEC). By the time an ARQ system discovers an error and re-transmits it, the re-sent data will arrive too late to be usable. Applications where the transmitter immediately forgets the information as soon as it is sent (such as most television cameras) cannot use ARQ; they must use FEC because when an error occur… black history month 2022 uk assemblyWeb20 okt. 2010 · EDAC_SYST_rel_005.pdf. 02e7e5226d384cc86f000000.pdf.
