Le yokugcina ulwazi medium kwimizobo computer

Enye yeengxaki ezibalulekileyo ezijongene kumnikazi ngamnye ikhompyutha, ezi zilandelayo: "Indlela yokuququzelela yokugcina ekhuselekileyo lwe data yedijithali." Nangona media zalamaxesha uluhlu olubanzi, kaninzi ixabiso abaninzi kubo liphezulu kakhulu amashishini kunye nabasebenzisi ekhaya. Noko ke, kukho isicombululo. Kuyimfuneko ukuba sihlolisise oko na iintlobo zosasazo kunye, banikwe imfuneko, ezona ukhetho kwi parameter "iindleko / iimpawu". Kwaye kufuneka ithathele ingqalelo ixesha elide ingqibelelo data.

Siqala inkcazelo. A eliphakathi Ngokushicilela technology computer - yinto into uyakwazi okanye enye indlela ukulondoloza kudluliselwa noko oscillations encoded elektroniki kwaye zinika ithuba kwakhona ukufunda (ukudlala) kwimo yalo yantlandlolo. Iimpawu eziphambili zezi zilandelayo:

- amathuba (okanye ukungakwazi) kwakhona lokurekhoda-;

- basebenzisa umgaqo yolondolozo ulwazi;

- iiyantlukwano lwesakhiwo kunye neendleko zizonke.

Le medium yokugcina iqhelekileyo kwiikhompyutha - i hard drive (hard drive, HDD). ukusetyenziswa kwayo kwenza kube lula ukwenza i-high speed yokugcina iinkcukacha digital kunye nokufikelela rhoqo kubo.

Ngaphakathi izindlu metal okoxande ezininzi ejikelezayo kwi ngesantya esiphezulu iglasi okanye iplastiki disks isale yayisoma ngemagnethi. Xa yokurekhoda ekhethekileyo intloko ngendlela ezithile magnetized komhlaba amanyala xa efunda kutshintshwe Imagnethi yomhlaba kunye eyiguqula ibe imiqondiso yombane, enyanisweni, ofumana amasuntswana - data. Okwangoku, le ophethe lwazi ngenkuthalo kusenzeka njengoko abenzi ngokuya zinika iindlela nzima drives ne umgaqo ezahlukeneyo ngokupheleleyo yokugcina - ngokusekelwe flash memory. In ingxenye ubunzima lorhwebo zojongano odibanisa ezi zixhobo kwi khompyutha yakho - ATA lothotho kunye USB. Benefits HDD - yinto ngendleko ephantsi gigabyte, ukuthembeka phezulu kunye nokusebenza, nsimbi nganye.

Amajelo eendaba alandelayo yokugcina - i optical disc. ukurekhodwa mgaqo isekelwe ekudalweni emathambekeni laser umqadi kwi lokuzala metal umaleko, kwicala elingaphandle apho kubonakalisa camera (zeendawana). Xa iqela umqadi funda ukuba ibekwe kwi kwingoma oyifunayo (tracks), kubonakala ukusuka zeendawana, swi yi lens ebhalwe photocell. Ekubeni ngobunzulu inkqubo kuxhomekeke ngqo kwi imeko umphezulu, sivelisa amasuntswana zombane, oko kukuthi, ukufunda ulwazi ezirekhodiweyo.

Kuxhomekeka iimpawu umqadi, kukho iintlobo ezahlukeneyo CD ukufunda nezixhobo (drives) kubo: CD ne-740 MB umthamo ezikhoyo, DVD kunye 4.7 GB and Blu-Ray nge-25 GB okanye ngaphezulu. idiskhi High-umgangatho kunye nokuphathwa ngenyameko uyakwazi ukugcina ulwazi amashumi eminyaka, kuba akukho ubethwa kwiinkalo ngemagnethi. Ukuze ufumane iinkcukacha ezingakumbi ukufunda zobuchwepheshe kweCD ingabhekiswa kwi-Internet.

Enye yezona ndlela nathembisayo kummandla eendaba - nto memory technology flash. flash Famous in mobile phones - oku isixhobo efanayo kakhulu. Kuba computer usebenzisa ezinye ujongano zangaphandle - USB kunye wada wabiliswa uphela. hard nge memory okuqinileyo-karhulumente kuthiwa. Ukuphunyezwa ilula: ngazo zonke izixhobo ezifakiweyo flash memory chip iiseli zabo, ngokungafaniyo iimodyuli inkumbulo eqhelekileyo, uyakwazi ukugcina lingatshintshanga isimo sayo de kweminyaka eli-10. Xa ukusetyenziswa kwamandla ayinamsebenzi, ekubeni akukho ezihambayo, kwaye nokuthembeka ubuninzi. Ithekhnoloji qho iphuculwe.

Kukho kwakhona isixhobo elilalela esekelwe kwi tape ngemagnethi (umgaqo osebenza iyafana amakhasethi endala). Umthamo ukuya ku 3TB.
