Usebenziso ngekhowudi kunye kokuhlaziya - kunzima?

Kunye nokusasazwa iikhompyutha zikwafune eyona ndlela obucokisekileyo iinkqubo zodluliselo lwedata. Kodwa apha kuvela ingxaki, leyo kukutshintsha indlela iinkcukacha eqhelekileyo kunye oluntu-efundekayo ukuze akwazi ukusebenzisa umatshini? Kwaye iziqalelo isisombululo sale ngxaki kukuba uku encoder kwaye ukucazulula ulwazi.

Le mbono "ikhowudi"

A iseti yeesimboli ezihambelana izinto ezithile kolwazi okanye iimpawu, ubize khowudi. Inkqubo eliya lenziwe, kuthiwa encoding. esephepheni Ulwazi yenziwa ukuze sishumayele data ngendlela compact nenokusebenzeka ngexesha transfer yayo nokulungiswa kwisixhobo computing. Ngexesha lenkqubo enkhowudingi kukuba ingasingasinga, ukuhlelwa odolwa idata ekhoyo. Iikhowudi japan zezi imveliso emva zokucazulula kwaye le njongo ukutshintshisana ngolwazi phakathi iikhompyutha ezahlukeneyo.

Kuthetha ukuthini zokucazulula?

Ukucazulula - utyando kwakhe iikhowudi injongo nguqu. Ngoko, xa, ngokutsho ikhowudi ethile ngozi, fumana ulwazi olufanelekileyo okanye into. Umzekelo umsebenzi onjalo bakhonze umzekelo phones nje. Ngoko ke, xa kukho iseti yamanani (kwaye enyanisweni, ikhowudi ithunyelwa ngokohlobo iimpawu zombane), ingena inkqubo yefoni ezenzekelayo. Apho ke decoded, nobuchwepheshe 'afunde' ukuba kufuneka ibe umrhumo. Ngokubanzi, ukucazulula - le kakhulu yinkqubo enzima, kodwa ukuba ucinga ngayo kakuhle kubume bayo, ukuba baqonde njani kwaye yintoni na eyenzekayo, hayi kunzima.

Njani inkqubo ikhowudi

Inkqubo encoding inokuba manual okanye ezenzekelayo. ulawulo yoko, ikhowudi manual ukuba pre-phambili, apho kuboniswe, oko kufanekisela. Emva koko, iimpawu ziyasetyenziswa ikhadi ngamanqindi okanye iteyiphu yephepha, baya kuqaliswa kwi khompyutha kunye ulwazi ngokutsha ufakwe kwi khowudi kumatshini.

ithandwa enkulu, hayi noko ngenxa ubulula bafumana indlela ikhowudi oluzenzekelayo. Ngoko ke, xa lwagqibelayo kubhaliweyo ngoncedo amagama, iimpawu aqhelekileyo kunye amanani uxwebhu wadala kwi computer. Ifayile ngenxa iya ukuhluzwa umatshini okhethekileyo. It buqonda yonke indlela, ukuze ngokukhawuleza ikhowudi umatshini kuyo lula ngakumbi ukuba ingasingasinga, uhlobo, ize isebenze data. Imeko nokhowudo ezenzekelayo phambi magama apho ikhowudi ethile elihambisana igama elinye. Ngale ndlela, akukho mfuneko yokuba ingcaciso ngentsingiselo yokuhlelwa yalo. Wenziwa lweenkcukacha ngohlobo eqondakalayo oomatshini, onokusebenza ngokuzithemba namandla processing ukuba baqwalasele izenzo eziyimfuneko. Kwaye usebenza iikhompyutha ngenxa yobukho ikhowudi iqhosha. Lo umzimba olunye ulwazi osetyenziswa yonke imisebenzi. Ukufunwa lwenziwa ngokwesiseko yokukhetheka ubudlelwane zobumnini nto. Ngokuqhelekileyo, uphendlo lwenziwa yi kwidilesi kancinci, kodwa ingasetyenziswa yaye serial inombolo yobhaliso ngaphandle ingcaciso engaphezulu.

Kukho nenye indlela ikhowudi xa data ezibekwe ngokoko ikuquletheyo. Ngamanye amazwi, le yokuhlela yenziwe, apho indima badlale mpawu ziphambili ocacisa.

Njani na ekufundeni

Kokuhlaziya ingcaciso efunyenweyo kuxhomekeke indlela enkhowudingi, uhlobo kunye neempawu eziphawula. Ngoko ke, ukuze ufumane ulwazi oludingayo, xa ukhetha indlela isalathisi eyahlukileyo kuyingxaki. Kubalulekile apha iqondo lokhuseleko kunye data nokhuselo. Xa efumana ngamaza ombane, izixhobo kuhlola nokuba ezinokuzisebenza. Ukucazulula - yinkqubo engelula, ekubeni ngexesha ukudluliselwa data esinxulunyaniswa kunye neziphumo nokulahlekelwa uphawu. Kwimeko yengqinisekiso impendulo isekelwe neempawu ezithile apho decodes ulwazi ofunyenweyo ngokungqinelana abalawuli data ekhoyo. Ukuba oku akwenzeki, i-computer lunikeza ukukhathaza nkqubo, nto leyo ethetha bazama kakhulu ezingeyomfuneko okanye ulwazi ayenzelwanga kuye. Isihloko engundoqo yavulwa, kwaye kuthathwa ukuba encoding kunye zokucazulula solwazi akusekho ukuba ubunzima ukuqonda.

iintlobo khowudi

Ukuba iisimboli naleyo into ethile okanye inkalo, i ikhowudi eso kuthiwa ngqo. Ukuba ikhowudi iqulathe ulwazi malunga kwidilesi ofunekayo, nto leyo ibonisa indawo ulwazi olufunekayo ekujoliswe kuyo. Isetyenziswa ukukhangela imithamo esikhulu solwazi. Code angamelwa njenge byte yokubini khowudi, ilizwi umatshini, kwaye iyunithi page. Usebenziso ngekhowudi kunye yokususa - oku kuphela ikhowudi operation. Musa ukulibala ngayo, uze akayi kuba nzima inkcazo kubo.
