Sekuvele kunabangani abaningana, abangaqondakali ezindabeni zesayensi yamakhompyutha, abangibuza umbuzo ofanayo. Abaqondi ukuthi kungani yabo idrayivu kanzima unayo ama-gig amancane kunokukhangiswa.
Lapho uthenga i-hard drive, i-pendrive, Mac noma i-iPod (okuyiqiniso ene-hard disk yayo ngaphakathi) amandla ayo akhonjiswa emaphaketheni womkhiqizo. Isibonelo ama-32GB, 128GB, 320GB, 500GB, 1TB amadiski, okungukuthi, "Ama-Gigabyte".
En isi-english Byte, akumele ididaniswe ne- "bit", ihunyushwa yi-octet. Ama-320Gbyte angama-320GigaBytes, afushaniswe ngama-320GB.
Yebo, sithenge iMacBook Air ene-128GB i-solid disk SSD, sidlule ebhokisini, safika ekhaya sayixhuma. Lapho sibheka umthamo onawo, siyamangala:
Okufanayo kwenzeka nge-hard drive yangaphandle, i-pendrive noma i-iPod ... I-128GB isibe ngaphezu kwe-121GB. Uma ufuna ukubheka ukuthi mangaki avela kukhompyutha yakho, kufanele ufake ifolda "ABANYE" i-del I-Launchpad bese uqala ithuluzi "I-Disk Utility", lapho kubha eseceleni yangakwesobunxele ungakhetha khona amadiski owafunayo nasekhoneni elingezansi kwesokudla kwesikrini uzobona imininingwane.
Ukulahlekelwa kuyahlukahluka ngosayizi okhangisiwe i-hard drive, kepha kuhlale kunomehluko. Ukhohlisiwe? Yebo no cha.
Lo mehluko kungenxa ye- izici eziningana. Isizathu esikhulu ukuthi ososayensi bamakhompyutha nama-aces wokumaketha abacabangi ngezibalo ngendlela efanayo.
Njengoba kubonakala kusithombe-skrini esingenhla, inani lediski eliphelele empeleni likhombisa ama-byte ayi-121 billion-odd: 121.332.826.112, ukuthi abe ngqo. Ngenxa yalokho, umuntu kufanele acabange ukuthi i-albhamu inayo ngempela leyo "gigs". Futhi yilokho abezentengiso abagcizelela ukuthi basithengisele idiski "128GB". Kuzwakala kukuhle kepha akulona iqiniso ngokuphelele.
Inkinga, njengoba sesibonile, ukuthi i-1 kilobyte ayilingani ngama-byte ayi-1000, kepha ngama-byte ayi-1024. Ngenxa yalokho, i-gigabyte eyodwa ayilingani nama-byte ayi-1 1.000.000.000 1.073.741.824 128, kepha ayi-134.217.728.000. Ngenxa yalokho, ukuze ibe ne-121.332.826.112GB “yangempela”, idiski kuzodingeka ibe ngama-byte ayi-1024, esikhundleni sama-XNUMX. Ukumaketha akukwazi ukuphindaphindeka ngo-XNUMX.
Ukugwema izinsolo zokukhohlisa noma okubi kakhulu, abakhiqizi nabathengisi bahlala bekhombisa ukuthi "Usayizi wangempela ungaba mncane".
Lapha, ezansi kwekhasi le-MacBook Air spec kusayithi lika-Apple.
Ngokuphikisana nalokho esikutshelwa kulo mlayezo, ayifomathi yini eyenza umehluko, kodwa indlela “yokwenza lula” ukubalwa. Impikiswano evame ukusetshenziswa ukuthi "kulula kumakhasimende." Ngokwami, ngingasho ukuthi i-128GB, ebhalwe kahle nangokugqamile kulebula lomkhiqizo, ithengisa kangcono kunenombolo eqondile efana ne-121.33GB.
Kusukela namhlanje, "ukumaketha kwe-giga" kukhanya kune "gigabyte".
Funda kabanzi - I-Apple inikeza i-Fusion Drayivu ezingeni lokungena le-21,5-intshi iMac
Akuqinisekisiwe ngokuphelele, ngabakhiqizi, akukhona ukumaketha, abenza ama-hard drive alowo sayizi hhayi eyangempela. Njengoba usho, abakhiqizi bathi i-1MB ingu-1000KB esikhundleni se-1024KB ngokusho kombono.
Ngifuna ukusho ukuthi ukumaketha kwabakhiqizi (okuyibo abafaka amalebula bese benza amabhokisi) kukuzungeze ukuze umthengi angadideki. Siyabonga ngokufaka.
Okuthile okufanayo kwenzeke kimi, umngani wathukuthela wagana unwabu ngoba uma ilaptop ithi idiski yakhe ino-450 GB esikhundleni sika-500 nangaphezulu lapho ebona ukuthi iMacBook Pro yami inamandla angama-499.7 GB, wacabanga ukuthi yebiwe ngaze ngachaza ukuthi kanjani ilusebenzile lolu daba futhi yehlisa umoya kakhulu lapho ibona ukuthi lapho ngiya eBootCamp esikhundleni sokushaya u-499.7 ibhalwe u-457 GB kuphela
Incazelo ye-athikili ayilungile. I-kilobyte uma ingama-byte ayi-1000 (10³) inkinga ukuthi isisekelo esingu-10 sisetshenzisiwe, futhi kuthiwani uma kungama-1024 byte ayi-1 kibibyte, noma yini engu-2 ofanayo ophakanyiswe waba ngu-20.
Bengifuna ukubeka u-2 emandleni we-10
Uqinisile ukuthi kwi-elekthronikhi yedijithali, uhlelo lwedesimali olunesiqalo se-10 alusetshenziswanga, okungukuthi, isethi yezinombolo ezisetshenziselwa ukukhiqiza zonke ezinye ziyi-10, ngakho-ke lapho sifuna ukwazi ukuthi mangaki amathuba ahlukahlukene esingawakhiqiza ngamadijithi amathathu ngedesimali kuzoba ukukhuphula isisekelo sohlelo sibe ngu-3, okuyi-10. Esimweni se-elekthronikhi yedijithali, okuyiyona okubhalelwa kuyo ama-hard drive nezinkumbulo zedatha, uhlelo olusetshenzisiwe lusisekelo sesibili Ngamanye amagama, kulokhu kungamadijithi amabili, "0" kanye "1", asetshenziselwa ukwenza zonke ezinye izinombolo. Sibe sesibiza lolu hlelo BINARY. Ukwazi amathuba akhona lapho sinamadijithi ama-3, siphakamisa i-BASE 3 kuye ku-2, okungukuthi, amabili akhuliswe aya kwamathathu, okungamathuba ayi-8. Esimweni sethu ababili abakhuliswe baba ngu-10 yilokho okunikeza u-1024, ngoba amandla abalwa ngamandla ka-2. Uma uqaphela, yilokhu engikwenzile ukuze ngikwazi ukufinyelela kumthamo we-134.217.728.000. Siyabonga ngokufaka kwakho!
Buff, ungenze ngacabanga… 😉.
Ukubalwa kulungile, engizokuya ngakho ukuthi kuya ngesilinganiso esisekelweni 2 (kanambambili) noma ku-base 10 (uhlelo lwamazwe omhlaba) ihlelo leziphindaphindo ze-byte liyahlukahluka. Kungaba yi-kibibyte ye-base 2 ne-kilobyte ye-base 10. Angisho ukuthi ukubala kwakho bekungalungile, kepha, njengoba ngingu-pejiguero, ukuphindaphindwa kwe-byte ku-base 2 kufanele kubizwe ngokuhlukile ngokusho kweleveli ye-IEC8000-13 :
«Lolu phiko lwachazwa yi-International Electrotechnical Commission (IEC) ngoDisemba 1998 futhi lwasungula izinga lokugcina ama-byte ayi-1024 ngesibizo se-KiB esikhundleni se-kB njengoba belinjalo phambilini futhi belibiza ngokuthi yi-kibibyte, ukulihlukanisa ne-kilobyte, ngoba Ngibe senginikeza amaphutha amaningi phakathi kwabo. " (Umthombo we-Wikipedia)
Ngakho-ke uma umenzi we-hard drive ekunikeza imininingwane kuma-kilobytes, isistimu yokusebenza kuma-kibibytes, kodwa-ke futhi ngephutha bakubiza ngama-kilobytes, into iphela ngokudideka kubathengi abaningi.
Ngiyabonga ngokuphendula, kubonakala kimi isihloko esithandeka kakhulu.
Siyabonga ngokucaciswa okusha ngeKibibyte. Abasebenzisi abasifundayo manje bazoba nomqondo ocace kakhudlwana.
Abagcini nje ngokuba nale nkinga, okubi kakhulu ukuthi uhlelo, izinhlelo njll ... ukuthi kudiski ejwayelekile kudinga ama-gig angama-35 ku-ssd badinga cishe ama-60, lihlole futhi uzobona, basithengisele umthombo- ithengise isithuthuthu, qaphela okuthengayo.
Ngicela ungiphendule lokhu …… ngine-ibook g4 enediski engama-40 GB, kepha ngemuva kokwenza amafomethi amaningi izinyanga eziyisi-5, ngiyabona ukuthi inani lama-GB selinciphile laze lafinyelela kulelo okwamanje, ngina-37,14 Ama-GB. Kungakho bachaze ngaphambilini?
Ngoba yize ama-40gb avele phambilini, manje sehle ngomthamo yize noma ngasikhathi sinye sathi amandla awo angama-40bg?
ngamafuphi, kucace bha. lapho ngithola umshini wami futhi ngawufometha okokuqala yathi umthamo wawo ophelele ngu-40GB. manje ngemuva kwamafomethi amaningi umthamo ophelele uthi ungama-37.14gb's.
kukhona okwenzekayo nge-hard drive yami =?
