Sele bekho abahlobo abaliqela, abangaqondakaliyo kwimicimbi yesayensi yekhompyuter, bendibuza umbuzo ofanayo. Abasiqondi isizathu sokuba I-hard drive ine gigs ezincinci kunokubhengezwa.
Xa uthenga i-hard drive, i-pendrive, IMac okanye i-iPod (ngokuqinisekileyo ine-hard disk yayo ngaphakathi) amandla ayo abonakalisiwe kwimpahla yokupakisha. Umzekelo 32GB, 128GB, 320GB, 500GB, 1TB disks, oko kukuthi, "IiGigabytes".
En isiNgesi Byte, ukuba ungabhidaniswa ne "bit", iguqulelwa yi-octet. I-320Gbyte yi-320GigaBytes, ishunqulelwe i-320GB.
Ewe, sathenga iMacBook Air nge-128GB idiski eqinileyo ye-SSD, sayongena ebhokisini, safika ekhaya sayifaka ngaphakathi. Xa sijonga amandla anawo, siyothuka:
Kuyafana nange-hard drive yangaphandle, i-pendrive okanye i-iPod ... I-128GB ingaphezulu nje kwe-121GB. Ukuba ufuna ukukhangela ukuba zingaphi ezivela kwikhompyuter yakho, kufuneka ungene kwifolda "ABANYE" del Launchpad kwaye uqalise isixhobo "Izixhobo zediski", apho kwicala lasekhohlo ungakhetha iidiski ozifunayo kwaye kwikona esezantsi ekunene kwesikrini uza kubona ulwazi.
Ilahleko iyahluka ngokobungakanani obubhengeziweyo hard drive, kodwa kusoloko kukho umahluko. Ukhe waqhathwa? Ewe nohayi.
Lo mahluko ubangelwa izinto ezahlukeneyo. Esona sizathu siphambili kukuba izazinzulu zekhompyuter kunye neeaksi zentengiso abakhulelwa kwimathematika ngendlela efanayo.
Njengoko kubonwe kumfanekiso ongasentla, ubungakanani bediski yonke bubonisa i-121 yeebhiliyoni ezingaqhelekanga: 121.332.826.112, Ukuchaneka. Ngenxa yoko, umntu kufuneka acinge ukuba i-albhamu inazo ngokwenene ezi "gigs". Yiloo nto ke igurus yentengiso inyanzelisa ukuba isithengisele i "128GB" disk. Iyavakala intle kodwa ayiyonyani ngokupheleleyo.
Ingxaki, njengoko sele sibonile, kukuba i-kilobyte enye ayilingani nge-1 byte, kodwa yi-1000 byte. Ngenxa yoko, i-gigabyte enye ayilingani ne-1024 byte, kodwa kwi-1. Ngenxa yoko, ukuba ne "1.000.000.000" yokwenyani, idiski iya kuba zii-1.073.741.824 byte, endaweni ye-128. Ukuthengisa akunakho ukuphindaphindeka nge-134.217.728.000.
Ukuthintela izityholo zobuqhetseba okanye ezimbi, abavelisi kunye nabathengisi bahlala bebonisa ukuba "Ubungakanani boqobo bunokuba buncinci".
Apha, emazantsi e-MacBook Air spec kwiphepha le-Apple.
Ngokuchasene noko sikuxelelwa kulo myalezo, ayifomati yintoni eyenza umahluko, kodwa indlela "yokwenza lula" ukubala. Impikiswano ehlala isetyenziswa kukuba "kulula kumthengi." Ngokwam, ndingathi i-128GB, ebhalwe kakuhle nangokucacileyo kwileyibhile yemveliso, ithengisa ngcono kunenombolo efana ne-121.33GB.
Ukususela namhlanje, "ukuthengiswa kwe-giga" kukhanya kune "gigabyte".

Akuqinisekanga kwaphela, ngabavelisi, ayithengisi, abenza ii-hard drive zobo bungakanani kwaye ayizizo ezokwenyani. Njengoko usitsho, abavelisi bayalela ukuba i-1MB yi-1000KB endaweni ye-1024KB ithi ithiyori.
Ndifuna ukuthi ukuthengisa kwabavelisi (ngoobani abafaka iilebheli kunye nokwenza iibhokisi) kuyirhangqe ukuze umthengi angadideki. Enkosi ngegalelo.
Into efanayo yenzekile kum, umhlobo wayenomsindo kuba ukuba ilaptop ithi idiski yakhe yayine-450 GB endaweni ye-500 nangaphezulu xa wabona ukuba iMacBook Pro yam yayine-499.7 GB, wayecinga ukuba ibiwe de ndicacise uwusebenzile lo mbandela kwaye wazola ngakumbi xa ebona ukuba xa ndisiya eBootCamp endaweni yokucofa u-499.7 ibhalwe kuphela i-457 GB
Inkcazo yenqaku ayilunganga. I-kilobyte ukuba zii-byte ezili-1000 (10 the) ingxaki kukuba isiseko se-10 sisetyenzisiwe, kwaye kuthiwani ukuba zii-1024 byte yi-1 kibibyte, okanye yeyiphi enye eyi-2 ephakanyiswe ukuya kwi-20.
Ndifuna ukubeka u-2 kumandla we-10
Unyanisile kwi-elektroniki yedijithali, inkqubo yedesimali enesiseko se-10 ayisetyenziswanga, oko kukuthi, iseti yamanani asetyenziselwa ukuvelisa zonke ezinye zili-10, ke xa sifuna ukwazi ukuba mangaphi amathuba ahlukeneyo esinokuwenza. ngamanani amathathu ngedesimali iya kuba kukuphakamisa isiseko senkqubo esiyi-3, eyi-10. Kwimeko ye-elektroniki yedijithali, leyo ekubhalelwa kuyo ii-hard drive kunye neenkumbulo zedatha, inkqubo esetyenzisiweyo isisiseko sesibini Ngamanye amagama, ngeli xesha ngamanani amabini, "0" kunye "1", asetyenziselwa ukuvelisa onke amanye amanani. Le nkqubo siyibiza NGOKUBANZI. Ukwazi amathuba akhoyo xa sinamanani ama-3, siphakamisa i-BASE 3 ukuya ku-2, oko kukuthi, amabini aphakanyisiwe ukuya kwisithathu, ngama-8 anokwenzeka. Kwimeko yethu ababini abaphakanyiswe baya kwi-10 yeyona nto inika u-1024, kuba amandla abalwa ngamandla ka-2. Ukuba uyayiqonda, yile nto ndiyenzileyo ukuze ndikwazi ukufikelela kumthamo we-134.217.728.000. Enkosi ngegalelo lakho!
Buff, undenze ukuba ndicinge… 😉.
Ukubala kuchanekile, into endiza kuya kuyo kukuba kuxhomekeke kumlinganiso kwisiseko 2 (i-binary) okanye kwisiseko se-10 (inkqubo yamanye amazwe) i-denomination ye-multiples ye-byte iyahluka. Ingay kibibyte yesiseko 2 kunye ne kilobyte kwisiseko 10. Anditsho ukuba ubalo lwakho belungalunganga, kodwa, ukuba yi-pejiguero, ukuphindaphindwa kwe-byte kwisiseko 2 kufuneka kubizwe ngokwahlukileyo ngokutsho komgangatho we-IEC8000-13 :
«Iyunithi yachazwa yiKhomishini ye-Electrotechnical yeHlabathi (i-IEC) ngoDisemba ka-1998 kwaye yasekwa imigangatho yokugcina i-byte ezili-1024 ngegama lesibizo le-KiB endaweni ye-kB njengoko yayinjalo ngaphambili kwaye yayibiza ngokuba yi-kibibyte, ukuyihlula kwi-kilobyte, kuba Ndanika iimpazamo ezininzi phakathi kwabo. (Umthombo weWikipedia)
Ke ukuba umenzi wehard drive ikunika idatha kwii-kilobytes, inkqubo yokusebenza kwii-kibibytes, kodwa ke ngempazamo bayibiza nge-kilobytes, le nto iphela kukudideka kuninzi lwabathengi.
Enkosi ngokuphendula, kubonakala kum njengesihloko esinomdla kakhulu.
Enkosi ngengcaciso entsha malunga neKibibyte. Abasebenzisi abasifundayo ngoku baya kuba nembono ecace ngakumbi.
Ayisiyiyo kuphela le ngxaki, eyona nto imbi kakhulu kukuba le nkqubo, iinkqubo njlnjl .. ukuba kwidiski eqhelekileyo kufuneka iigigs ezingama-35 kwi-ssd zifuna phantse i-60, zijonge kwaye uya kubona, basithengisele iqula- uthengise isithuthuthu, lumka ngento oyithengayo.
Nceda ungandiphendula ngale ndlela …… ndinencwadi ye-g4 enediski engama-40 GB, kodwa emva kokwenza iifomathi ezininzi kangangeenyanga ezintlanu, ndiyabona ukuba inani le-GB lehlile lide lifikelele kule ngoku, ndinama-5 Ii-GB. Kungenxa yesi sizathu le nto bebecacisile ngaphambili?
Kungenxa yokuba nangona i-40gb yavela ngaphambili, ngoku yehlile kwisikhundla ngaphandle kwento yokuba ngaxa lithile yathi umthamo wayo wawuyi-40bg?
Ngamafutshane, icace gca. xa ndifumene umatshini wam kwaye ndayifomathilela okokuqala yathi umthamo wayo uphela yi-40GB. ngoku emva kweefomathi ezininzi amandla apheleleyo athi ngama-37.14gb's.
Ngaba ikhona into eyenzekayo nge-hard drive yam =?
