Yintoni na ukuguqukela amajelo?

Zonke iinethiwekhi ezikhoyo uthungelwano ukunika imisebenzi efunekayo Ungasebenzisa iintlobo ezimbini uqhagamshelo - circuit ziguquka, kunye (okanye) imibekelelo. Yintoni na kwaye njani ukuba zahlukile enye kwenye?

Makhe siqale, njani womnatha wesiphaluka-ugesi. Bavela phambi kunoogxa babo kunye iipakethi isenza, kunjalo, ngokungamangalisiyo phofu, kulula ngakumbi ukuphumeza. Umzekelo olothusayo lobuninzi uthungelwano elisebenzisa utshintshe nje zeesekethe - link ngefowuni. Kucacile ukuba ukuze ukuvumela yababhalisi ezimbini uqale ukuxoxa, kufuneka ukuseka i uxhulumaniso phakathi kwabo. Umbhalisi umqalisi olukhawulezileyo inani leyo enyanisweni umyalelo izixhobo zesikhululo yomnxeba (badla) therebetween indawo, qhagamshela kakuhle imigca emibini - ukusuka umqalisi kwaye ukusuka transponder (umzekelo, xa izikhokhelo abakhonzwa kwisitishi enye). Ngaphambili, le isicelo okuva mechanical kwi ezilula abenzi sikhundla, ngoko, kunye nesiqalo nokufika izisombululo digital, ukuphunyezwa zotshintsho, kodwa isimiso esifanayo. Circuit usuke ibonelela ababhalisi kunye elizimeleyo line, leyo iintsalela eyabelwe kude kube ekupheleni kweseshoni. Izinto eziluncedo nazi: ukuthembeka phezulu, akukho mfuneko yokuba ekudluliseni iipakethi yolawulo. Nangona kunjalo, le ndlela eqhola kunye nenani lwababhalisi iba neyilahleko kakhulu, ekubeni inani lamajelo ulinganiselwe ngokwasemzimbeni. Nditsho ukuzama ukusombulula le ngxaki usebenzisa itywina ngumlinganiselo wexeshana kuphela, isisombululo ezithile wethutyana. Ngaphezu koko, usuke yesekethi ethile enkulu - umgca wonxibelelwano ixakekile lonke ixesha nokuba akukho utshintshiselwano ngolwazi phakathi izikhokhelo. Ngokomzekelo, ngexesha incoko yefowuni, uyakwazi usixhome ejikeleza ikhompyutha kunye yimicimbi yaso - umbhobho uya kugcinelwa ngabo de uphawu iya ukwaphula link.

Kungenxa yoko le nto amajelo commutation kamva indawo weza indlela eya ngepakethi utshintshayo. ukusebenza yayo ibandakanya encoding kunye nezahlulelo wadlulisela umsinga data kwinani iipakethi ngabanye zisekelwe kwisamkeli link zizonke kudluliselwa kwaye kukho zidityaniswe zibe feed. Ukuze siqonde neeyantlukwano iindlela ezimbini, singakwazi ukusebenzisa isivumelwano lomgca yezothutho: xa umgca ziguquka yesekethe imelwe umkhondo kaloliwe, kwaye flow data - lo ukwakhiwa ezahlukeneyo iimoto. Kucacile ukuba indlela ulibaziseko landela zinqabile kakhulu, kwaye nokuthembeka omnye enyangweni. Ngelo xesha, le umkhondo ngexesha elifanayo Awukwazi ukususa zililo ezimbalwa. Kodwa imigca ipakethi ziguquka - umendo-high speed kunye intshukumo multiband. I impahla (i iipakethi ezidluliselwa) yahlulwe yaba koomatshini ezininzi kokudlulela kwi nokuphuma kwezinye iindlela zothutho, kufika eYerusalem, apho ibandla yasekuqaleni. Kulo mzekelo, indlela - ijelo lonxibelelwano, yaye oomatshini abo iipakethi data. Bona bahlalisene ngoxolo kwindlela enye, phantse ngaphandle kokuphazamisa iintshukumo zomnye. Ngaphandle - ukuxinana, iirobhothi kunye neemeko ezingaqhelekanga (oku kulibaziseka). Nokuba matshini azikafiki kwindawo, ikopi yesicelo inokuthunyelwa kwakhona. nomthamo ezidluliselwa ngeyunithi nganye xa ulwazi ipakethe ixesha iphezulu kakhulu kunaleyo kwimeko lwezitishi.

Ngokubanzi, usuke ukuswitsha nantoni na utshintsho ithi. Xa njengobuchule womnatha yenza indlela yokuba data ukunqumla. Le peculiarity siyifumana kwindlela intlangano yayo. Usuke akuyomfuneko ukuba mazingabhidaniswa umsebenzi yomgudu kukuba ukufumana ndlela ilungileyo.
