Ukugcinwa kwedatha kuyinqubo lapho amafayela namafolda agcinwa kudivayisi yememori, kungakhathaliseki ukuthi i-hard drive yangaphakathi noma yangaphandle, i-flash drive, nanoma yiluphi olunye uhlobo lwemidiya. Umgomo wokulondoloza uwukugcina amafayela evikelekile futhi uqinisekise ukuthi ayatholakala uma kudingeka.
Ziningi izindlela zokugcina idatha, kodwa okuvame kakhulu ukusebenzisa i-hard drive. I-hard drive iyithuluzi lenkumbulo eliqukethe amapuleti azungezayo agcina idatha emikhakheni kazibuthe. Amadrayivu aqinile angaba ngaphakathi (afakwe kuyunithi yokucubungula emaphakathi) noma angaphandle (axhunywe kuyunithi yokucubungula emaphakathi ngekhebula).
Enye indlela yokugcina idatha ukusebenzisa ama-flash drive, aziwa nangokuthi ama-solid state drives. Ama-flash drive awanazo izingxenye ezinyakazayo ngakho-ke ayashesha futhi anokwethenjelwa kakhulu kunama-hard drive. Kodwa-ke, ama-flash drive ngokuvamile abiza kakhulu kunama-hard drive futhi anomthamo omncane wokugcina.
Namuhla, abantu abaningi basebenzisa izinsiza zesitoreji samafu ukuze balondoloze futhi babelane ngamafayela. Izinsizakalo zesitoreji samafu zinikeza izinzuzo eziningi, njengokuvumelana nezimo nokufinyelela kumafayela noma yikuphi. Nokho, kukhona nezinye izingozi ezihlobene nokusebenzisa izinsiza zokugcina amafu, njengokuntshontshwa kwedatha nokugebenga.

Isitoreji kukhompyutha:
Isayensi yekhompiyutha isayensi efunda ukutholwa, ukugcinwa, ukucutshungulwa, ukudluliswa kanye nokubuyiswa kwedatha. Isitoreji kukhompyutha sibhekisela endleleni idatha egcinwa ngayo kudivayisi yokugcina, njenge-hard drive noma imemori ye-flash.
Idatha ingagcinwa okwesikhashana noma unomphela. Ukuthi idatha igcinwa kanjani kuncike ohlotsheni lwedatha nokuthi izosetshenziswa kanjani. Isibonelo, idatha yesikhashana ivamise ukugcinwa ku-RAM, kuyilapho idatha engunaphakade igcinwa kuma-hard drive.
Idatha ingagcinwa ngokulandelana noma ngokungalandelani. Indlela idatha egcinwa ngayo incike ekusetshenzisweni okuhloswe kukho. Isibonelo, idatha okufanele icutshungulwe ngokulandelana igcinwa ngokulandelana, kuyilapho idatha okungafanele icutshungulwe ngokulandelana igcinwa ngokungalandelani.
Idatha ingagcinwa endaweni noma emafini. Indlela idatha egcinwa ngayo incike ekusetshenzisweni okuhloswe kukho. Isibonelo, idatha ezocutshungulwa endaweni igcinwa endaweni, kuyilapho idatha ezocutshungulwa emafini igcinwa emafini.
Siyini isitoreji kukhompyutha:
Isitoreji kukhompyutha sibhekisela endleleni idatha nolwazi olugcinwa ngayo. Idatha ingagcinwa endaweni noma emafini. Isitoreji sasendaweni sisho lapho idatha ilondolozwe kudivayisi, njenge-hard drive noma i-solid state drive. Isitoreji samafu sisho lapho idatha igcinwe kuseva ekude futhi ingafinyelelwa nge-inthanethi.
Indlela isitoreji esisebenza ngayo kukhompyutha:
Isayensi yekhompiyutha isayensi ezinikele esifundweni sekhompiyutha. I-Computing ihlukaniswe ezindaweni eziningana, phakathi kwazo ukugcinwa kwedatha. Isitoreji kukhompyutha yikhono lokugcina idatha nolwazi ngokuphephile nangempumelelo.
Kunezinhlobo ezahlukene zesitoreji kukhompyutha, okuhlanganisa ama-hard drive, amadivaysi ememori ye-flash, ama-optical disks namadiski kazibuthe. Ngayinye yalezi zinhlobo zokugcina inezici zayo kanye nezinzuzo zayo.
Ama-hard drive awuhlobo oluvame kakhulu lokugcina kukhompyutha. Ama-hard drive akhiwe ngochungechunge lwamapuleti azungeza ngesivinini esikhulu. Idatha igcinwa kumapuleti ngesimo se-pulse magnetic.
Amadivayisi ememori ye-Flash awuhlobo olusha lwesitoreji. Imishini yememori ye-Flash ayinazo izingxenye ezihambayo, okuzenza zibe zincane futhi zibe lula kunama-hard drive. Imishini yememori ye-Flash nayo iyashesha futhi ingabamba idatha eyengeziwe.
Ama-Optical disks awuhlobo olungavamile lokugcina. Ama-Optical discs akhiwe ungqimba olukhanyayo olurekhodwa ngedatha ngendlela yama-pulses okukhanya. Ama-Optical disks anensa kunama-hard drive kanye namadivayisi ememori ye-flash, kodwa anomthamo omkhulu wokugcina.
Amadiski kazibuthe awuhlobo olungavamile lokugcina. Amadiski kazibuthe akhiwe ungqimba olubukisayo olurekhodwa ngedatha esesimweni sama-pulses kazibuthe. Amadiski kazibuthe ayanensa kunama-hard drive kanye namadivayisi enkumbulo ye-flash, kodwa anomthamo omkhulu wokugcina.
Izinzuzo zesitoreji kukhompyutha:
Isayensi yekhompyutha iyisiyalo esibaluleke kakhulu emhlabeni wethu namuhla. Kusinikeza izinzuzo eziningi, njengokwenza lula nokwenza imisebenzi ngokuzenzakalelayo, ukugcina inani elikhulu lolwazi, kusivumela ukuba senze izibalo eziyinkimbinkimbi nokuhlaziya, njll. Isitoreji kukhompyutha singenye yezinzuzo zako eziningi.
Ukugcinwa kwekhompyutha kusivumela ukuthi sigcine imininingwane eminingi ngokuphepha nangempumelelo. Singakwazi ukugcina idatha ku-hard drive, i-flash drive, noma iseva yamafu. Ngayinye yalezi zindlela inezinzuzo zayo kanye nokubi.
Ama-hard drive athembekile kakhulu futhi angagcina inani elikhulu lolwazi, kodwa asengozini yezingozi nokungcoliswa kothuli. Amadrayivu e-Flash mancane futhi ayaphatheka, kodwa abiza kakhulu futhi anendawo yokugcina encane. Amaseva wamafu adume kakhulu kulezi zinsuku njengoba esivumela ukuthi sifinyelele idatha yethu noma kuphi nanoma nini, kodwa kufanele siqaphele ngokuvikeleka kwedatha yethu.
Ngokuvamile, ukugcinwa kukhompyutha kusinikeza izinzuzo eziningi. Kusivumela ukuthi sigcine inani elikhulu lolwazi ngokuphepha nangempumelelo. Singafinyelela idatha yethu noma kuphi nanoma nini. Ngaphezu kwalokho, isisiza ukuba senze lula futhi senze imisebenzi ibe lula.
Ububi besitoreji kukhompyutha:
Idatha egcinwe emafini ingaphansi kwengcuphe ephezulu yokugetshengwa.
Idatha egcinwe emafini idinga uxhumano lwe-inthanethi ukuze ifinyeleleke, okusho ukuthi ingase ingafinyeleleki esimeni sokunqamuka kwe-inthanethi noma izinkinga zokuxhumana.
Idatha egcinwe emafini ingase isuswe ngephutha noma ngenhloso umhlinzeki wesevisi yamafu, okungase kuphumele ekulahlekeni kwedatha.
Idatha egcinwe emafini ingase ibe ngaphansi kokukopishwa okungagunyaziwe futhi isetshenziswe umhlinzeki wesevisi yamafu.
Idatha egcinwe emafini ingase ibe ngaphansi kokufinyelela okungagunyaziwe yizinkampani zangaphandle (isibonelo, esimweni sokunqatshelwa kokuhlaselwa kwesevisi).
Siyini isitoreji ku-Informatica Wikipedia?
Isitoreji kukhompyutha yindlela idatha nolwazi okugcinwa ngayo kukhompyutha. Isitoreji singenziwa ngezindlela eziningi ezahlukene, kuye ngohlobo lolwazi olugcinwayo. Ulwazi lungagcinwa endaweni ku-hard drive noma kwi-tape drive, noma lungagcinwa ukude kuseva yesitoreji noma emafini.
Kuyini ukugcinwa kanye nomsebenzi wako?
Isitoreji kuwumsebenzi wekhompyutha okuvumela ukuthi ulondoloze amafayela nedatha. Idatha ingagcinwa ku-hard drive, tape drive, noma i-floppy disk. Umsebenzi wesitoreji ukuvumela idatha ukuthi ifinyeleleke lapho kudingeka.
