Kune atove shamwari dzinoverengeka idzo, dzisiri kunzwisiswa musainzi yemakomputa, dzinondibvunza iwo mubvunzo mumwe chete. Ivo havanzwisise kuti nei yavo hard drive has zvishoma gigs pane kushambadzirwa.
Kana isu tichitenga hard drive, pendrive, Mac kana iPod (iyo yechokwadi ine dhisiki rayo mukati) kugona kwayo kunoratidzwa pane chigadzirwa chigadzirwa. Semuenzaniso 32GB, 128GB, 320GB, 500GB, 1TB disks, ndiko kuti, "Gigabytes".
En English byte, kwete kuvhiringidzwa ne "bit", inoshandurwa ne octet. 320Gbytes ndeye 320GigaBytes, yakapfupikiswa 320GB.
Zvakanaka, takatenga MacBook Air ine 128GB solid disk SSD, takapfuura nepakati pebhokisi, tikasvika kumba tikariisa mukati. Kana tichitarisa kugona kwayakaita, tinoshamisika:
Izvo zvinoitika neiyo yekunze hard drive, pendrive kana iPod ... Iyo 128GB yave kungodarika 121GB. Kana iwe uchida kutarisa kuti mangani anoonekwa pakombuta yako, iwe unofanirwa kungoisa folda "VAMWE" Del Launchpad uye wotangisa chishandiso "Dhisiki Rinobatsira", uko mubharaki reruboshwe iwe unogona kusarudza madhisiki aunoda uye ruzivo rwunoonekwa mukona yezasi yekurudyi kwescreen.
Kurasikirwa kunosiyana zvinoenderana nesaizi yakashambadzirwa hard drive, asi panogara paine mutsauko. Wakambobiridzirwa here? Hongu uye kwete.
Musiyano uyu unokonzerwa zvinhu zvakasiyana. Chikonzero chikuru ndechekuti macomputer masayendisiti uye ekushambadzira aces havafungi nezve masvomhu nenzira imwecheteyo.
Sezvinoonekwa mumufananidzo wepamusoro, iyo yakazara dhisiki inonyatso kuratidza 121 bhiriyoni-odd byte: 121.332.826.112, kuti ive chaiyo. Nekudaro, mumwe anofanirwa kufunga kuti dambarefu rine izvo chaizvo "magig". Uye ndizvo izvo gurus rekushambadzira rinosimbirira kutaura kuti vatitengese "128GB" disk. Zvinonzwika zvakanaka asi hachisi chokwadi zvachose.
Dambudziko, sezvatatoona, nderekuti 1 kilobyte haina kuenzana mabhuru 1000, asi 1024 byte. Nekudaro, 1 gigabyte haina kuenzana ne1.000.000.000 byte, asi 1.073.741.824. Nekudaro, kuve ne "chaiyo" 128GB, dhisiki rinofanira kuve 134.217.728.000 byte, pachinzvimbo che121.332.826.112. Kushambadzira hakukwanisi kuwanda ne1024.
Kuti udzivise kupomerwa kwekunyengera kana kwakanyanya, vagadziri nevatengesi vanogara vachiratidza kuti iyo "Saizi chaiyo inogona kunge iri diki".
Pano, pasi peMacBook Air spec peji pane saiti yeApple.
Kupesana nezvatinoudzwa mune ino meseji, haisi fomati chii chinoita musiyano, asi maitiro ekuti "kurerutsa" kuverenga. Iyo nharo inowanzo shandiswa ndeyekuti "zviri nyore kumutengi." Ini pachangu, ndingati iyo 128GB, yakanyorwa mushe uye pachena pane chigadzirwa chigadzirwa, inotengesa zvirinani kupfuura iyo chaiyo nhamba yakaita 121.33GB.
Kubva nhasi, "giga kushambadzira" yakareruka pane "gigabyte".
Dzidza zvimwe - Apple inopa Fusion Drive pane yekupinda-chikamu 21,5-inch iMac
Hazvina chokwadi zvachose, ndivo vagadziri, hakusi kushambadzira, vanoita madhiraivhi akaomarara ehukuru ihwohwo uye kwete iyo chaiyo. Sezvaunotaura, vagadziri vanoraira kuti 1MB i1000KB pachinzvimbo che1024KB zvinotaurwa nedzidziso.
Ndiri kureva kuti kushambadzira kwevagadziri (ndivanaani vanoisa zvinyorwa nekugadzira mabhokisi) kutenderedza kuitira kuti mutengi asavhiringidzika. Ndatenda nekuisa.
Chimwe chinhu chakafanana chakaitika kwandiri, shamwari yakatsamwa nekuti kana iyo laptop yakati dhisiki rake raive ne450 GB pachinzvimbo che500 uye nezvimwe paakaona kuti yangu MacBook Pro yakaratidza 499.7 GB yekugona, akafunga kuti yakabiwa kusvika ndatsanangura kuti sei yakashanda nyaya uye yakadzikama zvakanyanya paakaona kuti pandakaenda kuBootCamp pachinzvimbo chekufona 499.7 yakanyorwa chete 457 GB
Tsananguro yechinyorwa ichi haina kunaka. Kilobyte kana iri 1000 mabheti (10³) dambudziko nderekuti base gumi rinoshandiswa, uye ko kana ari gumi nemaviri byte iri 10 kibibyte, kana chii chakafanana 1024 chakasimudzwa kusvika makumi maviri.
Ini ndaida kuisa 2 kusimba re10
Muri kutaura chokwadi kuti mune zvemagetsi zvemagetsi, iyo decimal system iyo ine base 10 haina kushandiswa, ndiko kuti, seti yenhamba dzinoshandiswa kuburitsa dzimwe dzese dziri gumi, saka kana tichida kuziva kuti mangani mikana yakasiyana yatinogona kuburitsa. nemitatu manhamba mune desimali yaisimudza hwaro hwegadziriro kusvika pa10, inova gumi. Panyaya yemagetsi emagetsi, inova iyo hwaro hwekunyora dhata pane madhiraivha akaoma uye ndangariro, iyo sisitimu yakashandiswa ndeye base mbiri. nguva ino manhamba maviri, "3" uye "10" ayo anoshandiswa kugadzira mamwe manhamba ese. Isu tinobva tadaidza system iyi BINARY. Kuti tizive mikana iriko kana tiine manhamba matatu, tinosimudza BASE 0 kusvika ku1, ndiko kuti, maviri akasimudzwa kusvika matatu, zvinova zvisere zvingaita. Mukati medu vaviri vakakwidziridzwa kusvika gumi ndizvo chaizvo zvinopa 3, nekuti kugona kwacho kunoverengerwa nemasimba e3. Kana iwe uchizviziva, izvi ndizvo zvandakaita kuti ndikwanise kusvika panosvika 2. Ndatenda nekuisa kwako!
Buff, wakandiita ndinofanira kufunga… 😉.
Kuverenga kwakarurama, zvandiri kuenda ndezvekuti zvichienderana nesiyero iri mu base 2 (binary) kana mu base 10 (nyika dzepasi rese) dhinominesheni rezvakawanda zvepabeti zvinosiyana. Chingave kibibyte chebase 2 uye kilobyte yebase 10. Handisi kuti kuverenga kwako kwanga kusiri iko, asi, uri pejiguero, kuwanda kwebheti iri base 2 kunofanira kudaidzwa zvakasiyana zvichienderana nezvinotaurwa neIEC8000-13 standard:
«Chikwata chakatsanangurwa neInternational Electrotechnical Commission (IEC) muna Zvita 1998 ndokusimbisa mwero wekuchengetera gumi nemakumi mana nematanhatu nemazita ezita reKiB pachinzvimbo cheKB sezvazvaimboita uye voidaidza kuti kibibyte, kusiyanisa ne kilobyte, sezvo iri Ini ndazopa zvikanganiso zvakawanda pakati pavo. " (Wikipedia sosi)
Saka kana mugadziri wedhisiki rakaomarara akakupa iyo data mumakirobyte, iyo sisitimu inoshanda mumabibibyte, asi vozokanganisa zvakare kuidana kuti kilobyte, chinhu chinopera mukuvhiringidzika kune vazhinji vatengi.
Kutenda nekupindura, ndinoiona iri nyaya inonakidza kwazvo.
Kutenda nekujekeswa kutsva nezve Kibibyte. Vashandisi vanotiverenga vava nezano rakajeka kwazvo.
Havasi ivo chete vane dambudziko iri, chakanyanya kushata ndechekuti iyo system, zvirongwa nezvimwe ... kuti mune yakajairwa dhisiki inoda makumi matatu nemashanu gigabyte muSD inoda vangangoita makumi matanhatu, vatarise uye iwe uchaona, vatotengesa isu tsime- yatengesa mudhudhudhu, chenjera zvaunotenga.
Ndokumbirawo mundipindure iyi …… ndine bhuku rebhuku g4 rine 40 GB disk, asi mushure mekuita fomati dzinoverengeka kwemwedzi mishanu, ndinoona kuti huwandu hweGG hwadzikira kusvika kune iyo izvozvi, ndine 5 GB's. Ichi ndicho chikonzero nei vakatsanangura pakutanga?
Nekuti kunyangwe 40gb yakaonekwa kare, ikozvino yadonha musimba kunyangwe pane imwe nguva ichiti kugona kwayo kwaive 40bg?
muchidimbu, zvakanyatsojeka. pandakawana muchina wangu ndikaufometha kekutanga, yakati huwandu hwayo hwese hwaive 40gb's. ikozvino mushure mekuverengera kwakati wandei huwandu hwenongedzo inotaura kuti ndeye 37.14gb.
pane chimwe chinhu chiri kuitika neangu hard drive =?
