Memory umthamo 1 GB - oku kangakanani?

Ngophuhliso zobugcisa computer kukho amagama amatsha nyaka ngamnye. Abantu basoloko ukusebenzisa igama elithi "gigabyte", kodwa akazange aqonde ngokupheleleyo ukubaluleka kwalo mbono, kuba yintoni na ukuphendula umbuzo malunga Ubungakanani benkumbulo ku-1 GB - oku kangakanani.

Yintoni gigabyte?

Phambi kokuba bajongane umbuzo othi "1GB - kakhulu okanye kancinci," kufuneka uqonde kakuhle unit imemori. Xa uninzi bezixhobo zombane esetyenziswa phambili pulses zombane yangoku. Le ndlela ivumela ukuba ukuqhubekekisa ingcaciso eninzi ngexesha elifutshane yaye unemilinganiselo kuphela ezimbini - "Ewe" okanye "Hayi". Le yunithi lincinane ngokuba bit ngokufundisayo.

Ngoncedo ziikhowudi kwikhompyutha ebekwe zonke kuyimfuneko data - umbhalo, imifanekiso, isandi njalo njalo. Ukwandisa ubume processing isantya, isigqibo senziwa ukuba ayichithe yonke umlambo ngokwamaqela - iseti enye ziikhowudi 8 babebizwa byte. Ngophuhliso zobugcisa ezifunekayo ukuze asebenze yonke umthamo omkhulu data, ngenxa yokuba oko yaqala ukubonakala ukwahlulwa entsha ngokwamaqela amakhulu.

Ukuze lula inkqubo wasengqondweni unikwe inombolo ziikhowudi e lilodwa, kwagqitywa ukusebenzisa isimaphambili le SI kwenkqubo leeyunithi. Ngenxa yoko, kukho kilobits, megabytes kunye neminye imilinganiselo ye-Ubungakanani benkumbulo ezakusebenziswa. Kodwa ke, ngokutsho SI enye, ixabiso umba ngamnye kwaba isimaphambili ngohlobo-10 ukusa kwinqanaba elithile. A ulwazi computer, ngenxa mbini yayo, emelwe ngohlobo ezimbini noko. Ngenxa yoku, ukuzimisela ngokuchanekileyo ubukhulu kangako badla ngokujongana ingxabano. Nangona umahluko okhoyo ukuzimisela ngqo inani ziikhowudi, amaxabiso somahluko ukuba consoles kunye umahluko omncinci babambanayo mncinci kakhulu. Ngoko ke, ngokutsho ezi zibalo, ngo-1 ikhilobhayithi ayiqukethanga 1000 bytes, lo gama 2 ¹⁰ - 1024 bytes.

Njani elinye gigabyte?

Isimaphambili "Giga" ukulungiselela inkqubo SI yi okt 1 billion Septemba ^10,. uncamathiselo ekufutshane "Giga" - "Mega", nto leyo 10 ^umphinda-3 ezincinane. Kodwa ezininzi zehlabathi, kuquka eRashiya, inani ngqo le bytes bubonwa ngokusebenzisa deuces kwi isidanga n-th, ngoko ke impendulo yombuzo zazingaphi MB 1 GB ngu-1024.

Ukuqhubeka ngamaxabiso ezincinci, kunokuba phinda ngo-1000 ezinye izibalo ezenziwe usebenzisa ezimbini 10 isidanga. Ngenxa yoko, GB 1 - yi-1024 * 1024 = 1048576 okanye kilobytes 1024 ³ = 1 073 741 824 bytes. Ukuze ufumane inani ziikhowudi e GB 1, ixabiso ifunyenwe kufuneka liphindaphindwe bytes 8, ukuba isimbuku ngaphezulu kwezigidi-gidi.

Ixabiso inkulu Ubungakanani benkumbulo

iiyunithi Mufumi kumetwa inkumbulo sele igqithile elide isimaphambili "Giga" abakumanqanaba eziliqela. Okwangoku, ixabiso inkulu isixa inkcazelo Yottabyte mnye. Xa kuthelekiswa 1GB 10 okanye ¹⁵ amaxesha, ngokutsho inkcazelo Russian, kumaxesha-20 ^{ukuya kuma-50.}

Phakathi Yottabyte gigabyte 4 zicwangciswe More isigqibo ngumthamo, nganye kunciphisa iqondo 10 ezintathu ngokusebenzisa inkqubo SI okanye, kwimeko yokubini, igunya ababini ukuya kwi-10.

Gigabyte - kakhulu okanye kancinci?

Yonke imihla ehlabathini ziveliswa izibalo ezahlukahlukeneyo, ukuze igcine ngumthamo opheleleyo apho 1 GB akwanelanga. Eli xabiso neze efanelekileyo nkqu umsebenzisi omnye - Ngoku umthamo RAM, leyo igcina idata esetyenziswa rhoqo, sele maxa wambi ngaphezulu eli xabiso. Ubungakanani ifilimu kwindawo ubude avareji malunga neyure ethatha ngaphezu nje gigabyte, nto leyo esisizathu sokuba isixa-mali imemori ixabiso ngokwayo omncinane, nangona ukubaluleka kakhulu xa kuqwalaselwa byte yi byte.

Intonga 1 GB - iphinde ibe yinto elidlulileyo, apho kunzima ukufumana. Ngoku, ukuba ukudlulisela ulwazi esebenzisa izixhobo voluminous ngakumbi, kuquka nzima drives yangaphandle, umthamo yayo ukufikelela terabytes ezilishumi, nto leyo amaxesha 1000 gigabytes ngaphezulu.
