Umthamo wememori 1 GB - lena kangakanani?

With ukuthuthukiswa ubuchwepheshe bama-computer kukhona imibandela emisha njalo ngonyaka. Abantu bavame ukusebenzisa igama elithi "igigabhaythi", kodwa wayengaqondi ngokugcwele ukubaluleka lo mqondo, ngoba lokho kungaba ukuphendula umbuzo mayelana nenani inkumbulo 1 GB hhayi - lena kangakanani.

Uyini igigabhaythi?

Ngaphambi esibhekana ngayo umbuzo "1GB - okuningi noma okuncane," kumelwe baqonde okushiwo imemori iyunithi. Ngo iningi kumadivayisi we-elekthronikhi asetshenziswa kucutshungulwa pulses kagesi lamanje. Le ndlela ikuvumela ukucubungula ulwazi oluningi ngesikhathi esifushane futhi has amanani amabili kuphela - "Yebo" noma "Cha". Le yunithi ubuncane ibizwa kancane ulwazi.

Ngosizo izingcezu in ikhompyutha usethe wonke kunesidingo idatha - umbhalo, izithombe, umsindo nokunye. Ukwandisa isivinini ishayela ukucutshungulwa, kwenziwa isinqumo ukuzobhidliza lonke ekusakazeni ngemacembu - isethi eyodwa 8 izingcezu nabizelwa ibhayithi. With ukuthuthukiswa ubuchwepheshe ezidingekayo ukusebenza zonke yenqwaba idatha, ngoba lokho kwaqala ukuvela division amasha amaqembu amakhudlwana.

Ukuze lula inqubo ukuqonda inani elithile izingcezu in ezidlula, kwanqunywa ukuba zisebenzisa isiqalo we SI simiso amayunithi. Ngenxa yalokho, lapho kilobits, wamamegabhayithi nezinye namagugu inani lememori. Kodwa, ngokusho SI olulodwa, ukubaluleka isici ngasinye kwaba Isiqalo ngesimo 10 ngezinga elithile. A Imininingwane ikhompyutha, ngenxa webumbacambili yayo, amelwe ngendlela ezimbili kancane. Ngenxa yalokhu, isinqumo olunembile ezidlula nenkanyiso encane babhekana ukungavumelani. Naphezu umehluko ekhona ekutholweni esiqondile inani izingcezu, amagugu ngokwehluka for aduduze nge umehluko elincane abangelutho. Ngakho, ngokuvumelana nalezi izibalo, ku-1 kilobyte olungekho amabhayithi 1,000, kuyilapho 2 ¹⁰ - 1024 bytes.

Indlela eyodwa igigabhaythi?

Isiqalo esithi "Giga" ngoba uhlelo SI kuyinto Septhemba ^10, okusho 1 bhiliyoni. okunamathiselwe eliseduze "Giga" - "Mega", okuyinto 10 ezincane izikhathi ^3. Kodwa eziningi zomhlaba, kuhlanganise naseRussia, inani eliqondile amabhayithi kunqunywa usebenzisa Deuces ngezinga n-th, ngakho impendulo yombuzo bangaki MB 1 GB ngu-1024.

Eqhubeka amagugu ezincane, esikhundleni yanda ngezinkulungwane 1000 izibalo okwengeziwe zenziwa usebenzisa degree ezimbili 10. Ngakho, GB 1 - kuyinto 1024 * 1024 = 1048576 noma amakhilobhayithi 1024 ³ = 1 073 741 824 bytes. Ukuze uthole inombolo izingcezu in GB 1, ukubaluleka etholwe kufuneka iphindaphindwe 8 amabhayithi, kokuba ingqikithi kancane angaphezu kwezigidi eziyinkulungwane.

Inani kunazozonke inani lememori

Sekuyisikhathi eside uMbusi amayunithi memory wawudlula Isiqalo "Giga" emazingeni eziningana. Okwamanje, obuyigugu kakhulu inani Imininingwane ingenye Yottabyte. Kuqhathaniswa 1GB 10 noma ¹⁵ izikhathi, ngokuvumelana definition isiRashiya, ezikhathini 20 ^{kuya 50.}

Phakathi Yottabyte igigabhaythi futhi 4 ahlelwe Okuningi sokunquma ivolumu, ngamunye okuyinto kunciphisa izinga 10s ku ezintathu ngokusebenzisa uhlelo SI noma, esimweni kanambambili, amandla ezimbili kuya ku-10.

Gigabyte - okuningi noma okuncane?

Nsuku zonke emhlabeni akhiqizwa izibalo ahlukahlukene, ukugcina umthamo isamba okuyinto 1 GB akwanele. Lokhu value neze ofanele ngisho umsebenzisi oyedwa - Manje-RAM ivolumu, okuyinto ugcina idatha asetshenziswa njalo, kakade ngezinye izikhathi idlule kwaleli nani. Usayizi ifilimu i ubude isilinganiso cishe ihora kuthatha nje phezu igigabhaythi, yingakho inani lememori ukubaluleka ngokwayo lalilincane, naphezu ezibaluleke kakhulu lapho sicabanga ibhayithi ngu Byte.

Induku ka-1 GB - liphinde into yesikhathi esidlule, okuyinto okunzima ukuzithola. Manje, ukuze uthumele ulwazi besebenzisa Amadivayisi voluminous ngaphezulu, kuhlanganise wangaphandle hard ngemoto, ivolumu ongafinyelela terabytes eziyishumi, okuyinto gigabytes Ezikhathini 1000.
