Ulwazi hard umthamo disk: ntoni na?

umthamo yokugcina ulwazi - ingcamango ebalulekileyo zokugcina. Ngasemva kwawo kukho ngokupheleleyo drive. Ngubani benziwa ezimbini indlela yayo yokubala. Babanike iziphumo ezahlukeneyo, kwaye akukho abawazi kulo mbandela abantu ezilahlekisayo.

Yintoni ingxaki?

Umntu Iinkqubo ulwazi kwesishumi kwinkqubo inani. Ngokwembali, yaye akukho namnye ayithethi ufuna ukuncama. Thina lula kakhulu. Le nto ndiyibhalayo amanani ukusuka kwi-0 ukuya ku-9 (abanye bathi ukusuka kwisi-1 ukuya kwi-10, kodwa ke oko akuthethi ukutshintsha). Kodwa ke computer iinkqubo idatha kwinkqubo yokubini. Oku kusekelwe kwi-0 (akukho uphawu), 1 (ombane ekhoyo). Kubonakala ukuba ulwazi besikhundla disk ezingamaphepha emiselwe binary okanye wokugqibela inkqubo inombolo. Nceda khumbula enye ingongoma ebalulekileyo. Kulo wokuqala 1 ikhilobhayithi ngu 2 ¹⁰ okanye 1.024 bytes. Eli xabiso ezi program, ngoko kumiselwe ubuninzi lolwazi, yonke windose i OS ' "namhlanje. Kodwa kwimeko yesibini, eli xabiso liza kuba ngoMatshi ^10, okanye 1000 bytes. Ngoko cinga abantu ulwazi futhi aqhube abenzi. Kuyinto nzima ukuqonda, umntu unako ukuthenga i-hard drive ezinye iimpawu, kunye OS "windose" ukubonisa ukuba ezinye iinkcukacha kancinane. Kulo mzekelo, ulwazi besikhundla disk nzima inkqubo yokubini kuya kuba ngaphantsi, nangenxa lokugqibela - ngakumbi. Kodwa isixa iinkcukacha egciniweyo kuhlala ingatshintshanga. Le yeyona iphambili kule meko ngendlela apho engenakubalwa.

recalculation

Senza kokubalwa kwakhona umzekelo 500 GB (ngokwendlela umenzi) drive kwaye isigqibo ilahleko ipesenti. Okokuqala, ekucaciseni ukuba isimaphambili "Giga" kwinkqubo ngeshumi le yi September ^10, yaye okubini - ^{30 2.} Ukuqala ukuphindaphindeka 500 Gb 10 ^9. Oku ubungakanani in bytes. Ukuya kwinkqubo yokubini kufuneka ixabiso kweziphumo 500 x 10 ⁹ umahlule ngo-2 ^30, yaye siza kuyithathaphi 465 GB. Oku kuya kuba umthamo yokugcina ulwazi kwinkqubo entsha. Okulandelayo thina ezichaza ipesenti ilahleko kwindawo therebetween yenguqu. Ukulungiselela le njongo 500 GB 465 GB uthabathe uze uwahlule isiphumo ngu 500 GB. Isiphumo ngu 0,07. Ukuba phinda eli xabiso 100 uze ufumane umahluko ipesenti. Kuya kuba 7%.

Kubonakala ukuba umthamo yokugcina obonisa OS "windose" yancitshiswa ngoko nangoko ixabiso ifunyenwe. Kaloku, ukuba uyaqonda umntu aliqonde. Kodwa kukho ezinye iimeko apho umthengi unesikhalazo engena evenkileni waza waqalisa ukulungisa izinto. Xa umthengisi efanayo ummangalelwa ukuba wathengisa "kuba wayenze isifungo" drive. Umntu akayiqondi into ubuninzi amandla hard drive - ixabiso njalo ngokwenene. Kodwa ixabiso layo kunokwahluka ngokuxhomekeka indlela yokubala. Kwaye ke therebetween umahluko yi-7%, nokuba umthamo. Oku kuyinyaniso kuzo zonke izixhobo zokugcina, kuquka drives flash kunye floppy disks, kunye CDs.

isiphelo

Umthamo ngokupheleleyo disk hard drives i parameter engundoqo apho abathengi bahlawula ingqalelo phambi kokuba uthenge. Kodwa kwangaxeshanye, bambalwa abantu bacinga ukuba ixabiso layo liya kuba ngaphantsi kwe-7% kule OS "windose". Kodwa ke kubalulekile ukuqwalasela uthabathe isixhobo esima elithile, ngoko awufuni uthenga yesibini drive.
