Inkcazelo into: inkcazelo, iintlobo kunye neempawu

Inkcazelo into ligama enokusetyenziswa ukuchaza iintlobo ezahlukeneyo izinto eziphathekayo. Phantsi kwezi nkqubo kunokuquka izenzakalo ukuba izinto okanye iipropati ezingaphathekiyo. Cinga izinto ulwazi lube ngokwemigaqo iimpawu zabo ezintle.

iimpawu yokuhlela

Kukho ukwahlukana ibe ngamaqela eziliqela. Zonke izinto data zihlelwa yi iintlobo zezinto phantsi ingqalelo, ubhekisela umfanekiso, ubukho (lokungabikho emsebenzini) yesandi. Makhe sihlolisise ezinye iinketho kule yunithi. Ngokomzekelo, into data esilula ozakuthathwa inombolo yomfanekiso, isandi, umbhalo. Kuba ezahlukeneyo ezintsonkothileyo luphawulwa ubukho iProtokhol, spreadsheets, iinkcukacha, hypermedia.

ukudlulisa ulwazi

Nayiphi na into ulwazi busenza ukuba ubukho inkcazelo ethile. Umzekelo, ukuba umthi transfer ulwazi yemfuza evumela ukuba bafumane ixesha lokuphumla ethile komthi omdala imbewu. Njengoko omkhulu umthombo kwimeko enjalo izenzo umoya. Kuxhomekeka imeko umthi limisela ixesha ukuphuma amathupha wavuleka, ukuvela amagqabi aluhlaza. imihlambi ezahlukeneyo iintaka ezifudukayo bayazi kakuhle iindlela zabo, baza emva kwabo kanye xa eziphaphazelayo, musa siphuma endleleni ekujongwe.

Iindlela okugcina ulwazi

Ukuqwalasela iintlobo ezahlukeneyo zezinto data, qaphela ukuba umntu isoloko ikhangela iindlela ukugcina ulwazi olubalulekileyo malunga isenzeko, injongo. Ubuchopho unoxanduva ezahlukeneyo lolwazi, basebenzisa iindlela zabo ugqithiselo lweengcombolo kwabanye abantu. Sisiseko oku kunokuba ikhowudi yokubini, nto leyo efana iiPC mihla. Ukuze amelane inkqubo inkcazelo iye isetyenziselwa injongo eyenzelwe yona, oko kuyenzeka ngoku ukukhetha iintlobo ezininzi yokosulela kunye nokugcinwa ixesha elide. Ukongeza kwimemori yangaphakathi, unako ukubeka inkcazelo ebalulekileyo ezahlukeneyo zosasazo ngemagnethi.

Iindidi ujiko ulwazi yokugcina

Nayiphi na into ulwazi kusindiswa ngeendlela ezahlukeneyo. I elula izimvo graphic okanye ukuboniswa. Oku yindlela abantu bakudala wazama Kwathi ukusuka kwisizukulwana ukuya kwisizukulwana ulwazi malunga ngezimanga zendalo, izinto. Phambi ixesha lethu ukugcina ezinye mizobo iliwa eyenziwe ngabantu bakudala. Ke kwangena imifanekiso, imizobo, iifoto, imizobo.

transmission sound

Ukwanako ukugcina i-technologies ulwazi nge ngoncedo izandi. Kwihlabathi yabantu zininzi izandi kunokugcinwa kwaye lwenziwe. isixhobo ekhethekileyo lokurekhoda lwasungulwa 1877. Njengoko ukwehluka ulwazi isandi kungathathwa umculo encoding. Oku kubandakanya ufihlo abalinganiswa izandi ezithile, ukutshintshwa elandelayo kokubhaliweyo isandi (njengoko iingoma).

yokuGqithisela umbhalo

Olu hlobo ngentetho encoding yabantu ngabalinganiswa ezikhethekileyo - iileta - izicelo iintlanga ezahlukeneyo. Wonke ubuzwe linolwimi lwalo, esebenzisa iiseti ezithile zabalinganiswa (amagama), sibonga kuso uboniswa. Ngenxa yale hlobo ikhowudi ulwazi lokubonakala wokushicilela wokuqala.

A umlinganiselo ubuninzi iinjongo kunye neempawu zazo ehlabathini mihla a ukudluliselwa data lwamanani. Nokufika yorhwebo, imali turnover, uqoqosho olu hlobo izinto lolwazi iye ingakumbi ezifanelekileyo imfuneko.

Systems of encoding wokwamanani kunokuba ezahlukeneyo. Phakathi ukhetho ezithandwayo mihla qaphela ividiyo. Kubandakanya kulondolozwa ulwazi oluthile ngohlobo imifanekiso "live". Loo indlela ufihlo kuye kwenzeka kuphela emva kokuba movie. Kodwa ke, nangona uninzi izinto ulwazi ngayo nayiphi na indlela kutshintshelwa kwamanye izizukulwana, nokuba kweli phakade zobugcisa computer thina imithombo ezinjalo, abangancedekanga okwangoku zabuqhinga iindlela ukulondoloza, encoding, ziyakusasaza inkcazelo. Ngokomzekelo yo fanekisela, cinga ulwazi oyivileyo. Sithetha ukutshintshwa iimpawu organoleptic, iminqweno, ivumba, Engadlanga zinto. njengokungathi lafaka Awukwazi ukumelwa ngendlela enebhakhowudi, kungaba kuphela amagama ukubonisa imvakalelo zabo neemvakalelo. Ngaphambi umbane kwemoto,-elide umgama ulwazi olubalulekileyo wadluliselwa ziimpawu ukukhanya elifihlakeleyo. Emva koko, le nkqubo sele lula kakhulu, ngokubuyisela amaza ezintsonkothileyo beza emoyeni.

encoding Binary njengendlela yokudlulisela ulwazi

Ngumdali we kwingcamango enjalo, oko kukuthi. E. owaseka lonxibelelwano digital mihla Klod Shennon. Loo nto iye yaba lula ukusebenzisa code yokubini ulwazi zosasazo. Emva kokufika kweekhompyutha (PC) kuqala aphuhliswe ngendlela processing wokwamanani. Kunye nokuphuculwa kweekhompyutha zobuqu iinketho zonyango, sesha, transfer amanani, isandi, ulwazi umfanekiso ziye zatshintsha kakhulu. Kule mihla, iinkcukacha ezibalulekileyo igcinwa kwi makhasethi Imagnethi yomhlaba okanye disks, amajelo osusekayo wogcino, laser akwazi. Njengomthombo ekhethekileyo inkcazelo ngoku skrolela iinkcukacha efumaneka kwi-Internet. Kuba retrieval, ukusetyenzwa, yokugcina ulwazi kule meko kusetyenziswa iindlela ezizodwa.

isiphelo

Nawuphi na umsebenzisi into data uneempawu ezithile. Unako naye ukuba enze izenzo ezithile, ezifana software yekhompyutha zisetyenziswa njengesixhobo. Majelo ingathatyathwa iyunithi oluzimeleyo iinkcukacha (ulawulo, ifayile, ifayile). Nesicelo nangobuchule ngexesha izinto data ezahlukeneyo, ungenza umbono epheleleyo iinkqubo kulindelekile okanye ezentlalo ngezimanga, kwakunye ukuchonga iindlela ukuba baqhubele phambili uphuhliso kunye yotshintsho isenzeko.
