Kwi-telecommunications, igama le- uplink libhekiselele kumnxeba ongenawo ucingo owenziwe ukusuka kumhlaba ukuya kwi-satellite ye-communications ejikeleza umhlaba. Ixesha elifanayo ngamanye amaxesha lisetyenziselwa ekunxibelelaneni kwikhomputha kwaye lithetha uxhumano lwe-wired (wireless) okanye lwangenantambo kwi- network yendawo yenethiwekhi (LAN) kwi- network network (WAN) .
Uplink ne Downlink
I- downlink yintsebenziswano eyenziwe kwindlela eyahlukileyo ye-uplink, mhlawumbi ukusuka kwi-satellite ukuya kumhlaba okanye kwi-intanethi yangaphandle ukuya kwinethiwekhi yendawo. Ukulandwa kwe-intanethi, umzekelo, uhamba nge-downlink kwidivaysi yokukhuphela ngelixa ukulayishwa kwe-Inthanethi kuhamba ngokuxhumeka kwe-uplink.
Iiplinks ziqhelekileyo zisetyenziselwa ukuthungelwano nge- satellites ukusabalalisa i- redio kunye ne-TV. Abasasazo bathumela izondlo zabo zeempawu ezivela kwisitishi somhlaba ukuya kwi-satellites ejikelezayo, inkqubo eyaziwa ngokuthi uplink satellite .
Izilwanyana kunye nabanye ababoneleli ngeenkonzo zokunxibelelana nabanomnxeba ngamanxeba ngamanye amaxesha kubhekisela kumzila wokunxibelelana ohanjisiweyo kumanethiwekhi abo njengendlela yokudlulisa i-uplink . Ezi uplink zingaphatha imilayezo yombhalo, ukulayishwa kwefayile ye-intanethi kunye nedatha ekhompyutheni ithunyelwe kumncedisi wenethiwekhi.
Iiplani ze-Uplink kwi-Computer Networks
Elinye i-hardware yenethiwekhi yekhomputha iquka iiplink ze-uplink ezenzelwe ukungena kwizixhobo zenethiwekhi . Ezi zibuko zivumela inethwekhi ukuba inxibelelane namanye amanethiwekhi angaphandle. Iiplani ze-Uplink kwii-routers zasekhaya, umzekelo, vumela ukuxhumeka kwiimodem e-broadband kunye ne-Intanethi.
I-Ethernet hubs , switches , kunye nee-routers ngokuqhelekileyo zikhetha enye yee- Ethernet zokungena njengekhonkco ye-uplink ephawulwe ngokukodwa kwiyunithi ngegama kunye / okanye umbala. Izithuthi zomnxeba zasekhaya zihlala zibhale le port "WAN" o r "Intanethi" esikhundleni se "uplink," kodwa ingcamango nomsebenzi ziyafana.
Ukuxhuma kwe-Uplink kunokusetyenziswa
- Ukuqhagamshela imodem ebanzi yokubambisa kwi- router yasekhaya yokufikelela kwi- Intanethi .
- Ukuxhuma enye i-uplink idivayisi (router, switch, hub) kwenye. Gcina iplani ye-uplink yoshicilelo olunye, umzekelo, kwi-port efanelekileyo yesinye ishintsho ukuze wandise ubungakanani benethiwekhi.
Ngakolunye uhlangothi, ukuhlanganiswa kwe-uplink akufanele kusetshenziswe
- Ukudibanisa iiplani ezimbini ze-uplink omnye komnye
- Ukuqhagamshela ikhompyutha kwichwep uplink
Qaphela ukuba, kumanethiwekhi ekhompyutheni yanamhlanje, ukudibanisa kukukhokelo. Nokuba udibaniso kwi-port uplink, ikhebula elifanayo okanye unxibelelwano olungenazintambo unokudlulisa idatha kokubili nakumacebo ekupheleni kunokuba "kuphela" okanye "phantsi." Imiqathango yokuphakamisa i-uplink kunye ne-downlink apha isebenza ekupheleni koxhumo oluqalisa ukudluliswa kwedatha.
Abaqeqeshi benethiwekhi bangabonisa ukuba i-Ethernet crossover cable ingasetyenziselwa ukuxhuma ikhompyutha kwi-port uplink okanye ukudibanisa iiplani ezimbini ze-uplink. Nangona ichanekile ngezobuchwepheshe, ukusetyenziswa kwezi ntlobo zonxibelelwano kuncinci.
Iinjongo eziBini kunye neNdawo ezabelwana nge-Uplink
Ingcamango yemveli yehardware yechwethi ye-uplink isekela kuphela izixhobo ze-uplink kuphela. Nangona kunjalo, ii-routers zasekhaya zamanqabaninzi zanamuhla zinikeza ichwethi enjongo ezimbini endaweni leyo, enye inokusebenza njenge-uplink okanye isango eliqhelekileyo kuxhomekeke kuhlobo lwefowuni oluxhomekeke kulo.
Ngaphambi kokuba izibuko ezinqabileyo zombini zithandwe, ezinye izixhobo zethungelwano ezindala zalungiselela ichweba eliqhelekileyo eduze kwe-uplink kwaye zidibanisa zombini kunye njengombini. Ngokukodwa, i-logic ye-hardware yale mveliso ixhasanise uxhulumaniso kwi-port uplink, okanye kwi-port ehlanganyelweyo, kodwa kungabini bobabini. Ukuxhuma amadivaysi kumabonko amabini wesiphathi esabelana ngokubambisa i-unit ukuba isebenze ngokufanelekileyo.
