Yintoni a hard drive disk

Nangona kukuba ngo izifundo kwisayensi yesikolo utitshala uyacacisa ukuba injani hard drive in uthungelwano lwehlabathi loo mbuzo idla wabuza. Abanye waphulaphula ngenyameko ingcaciso, abanye baba nomdla. Kweli nqaku, sikhumbula bandilibele elide - ndinixelele into hard drive.

Kaloku, enyanisweni, disk hard layo? Igama elithi yavela ngemihla zokuqala zophuhliso abangakhange wabonakala ikhompyutha, xa amakhadi punch sele sasesiwuyeka iiteyiphu Imagnethi yomhlaba kunye floppy disks, kunye CDs. Mhlawumbi uninzi lwabanini yekhompyutha namhlanje ayazi noyena into floppy diski, nendlela babheka. Kodwa ngaphandle bewagqala, akunakwenzeka ukuba ukuphendula umbuzo wokuba yintoni na hard disk. I tape Imagnethi (as in ikhasethi emanyelwayo) njengomthuthi lwe data digital ixesha enilichithe - okukule filimu ukuvumela ukuba ngokukhawuleza ukufumana isabelo oyifunayo. Baye indawo yi floppy disks. Bona disks Polymer omabini la maqela isale umaleko ngemagnethi. Kokuba kucingelwa ukuba ekhasethini zanyibilika kanye kungena disc. Ukukhusela nxamnye imikrwelo, yena wabekwa sikwere-ezimile Imvulophu zeplastiki ngaphaya - ukufumana i floppy diski. Idatha afunde drive. amandla floppy ibincinane - ekulula zityediwe (ifom wachacha), kwaye nkqu agobe. Zombini owokuqala yesibini kwakungenakwenzeka ukuba benze - oko kukhokelela surface iimpazamo ngenxa yomonakalo umaleko magnethi (ingakumbi begoba). Kubalulekile ukuba ifloppy diski yaziwa ngokuba KMT - floppy disks.

Kwangaxeshanye, lithe laqhenqetha isixhobo eyodwa electromechanical i ebuntsimbi okanye iglasi disk isale magnetic (chromium oxide), a hybrid izindlu iimoto kunye ngesantya esingaguqukiyo. Inxalenye yekhompyutha ukujikeleza imiyalelo efundiweyo ezifunyenweyo \ nokuzibhala computer. Ngokungafaniyo floppy disks yile ilandelayo: a umthamo omkhulu, ukuthembeka ophezulu, ukusebenza, ukungakwazi agobe, ngenxa yokuba umzimba, kwaye ngokwawo i drive kwaba metal.

Yintoni hard drive? It is uthe isixhobo - le HDD (yokugcina ngokusekelwe nzima disks magnetic). Amanye amagama - HDD, hard drive, njl

Modern drives hard ambalwa Disks kwi axis eqhelekileyo, nokunyusa ngumthamo opheleleyo. Ngokungafaniyo amakhasethi, intloko yeyokufundwa ngexesha tyando wadibana komhlaba, yabaleka phezu umsantsa emoyeni (hayi ngaphezulu kwe-10 NM). Umhlaba ubucotha ukujikele- kuxhomekeke kwisantya: uninzi imodeli umncedisi naziphi drives ukuya ku 15,000 Rev / min, njengomgangatho ezibonayo - 7200, kunye neendleko-olusebenzayo iintlobo "yanelani nemadlana" 5400. Nangona kutshanje wabonakala okrelekrele i HDD, utshintsho ngesantya stepwise ngokuxhomekeke umthwalo.

Aplikheyishini uqhagamshelwano kwikhompyutha -. IDE, wada wabiliswa uphela, USB, SAS, njl Ethetha USB, asinakho ukuba onjalo yangaphandle hard drive.

Ngawo onke amancedo nzima drives, baye kudala zaba amacandelo yangaphakathi ye computer, ibekwe kwinkqubo unit le. zone zezala yokupaka (iinkcukacha ngemagnethi Kwasika esiswini intloko buyo, lo mayiqhagamshelane mechanical) ukuvelisa wavumela HDD ephathekayo. Oku kuyafana hard drive, kodwa eyenzelwe iimeko unzima kakhulu. Le kwizindlu ukuvula block neeletroniki ezithengiswayo. Ixhume kwikhompyutha nge USB okanye Ucingo lomlilo. Isantya othini uqobo aziphelelanga 5400 Rev / min (ukuncipha power).
