Awoodda Memory 1 GB - taasi waa immisa?

Iyadoo horumarinta technology computer waxaa jira heshiis cusub sannad kasta. Dadku waxay inta badan ereyga "gigabyte" isticmaalaan, laakiin ma aysan si buuxda u fahmaan muhiimadda ay leedahay in fikrad this, sababta oo ah waxa aan ka jawaabi karin su'aal ah oo ku saabsan qadarka xusuusta 1 GB - taasi waa sida ay u badan.

Waa maxay gigabyte ah?

Ka hor inta aan la su'aasha ah ee ka qaban "1GB - badan ama wax yar," Waa in aad fahmi nuxurka cutubkan xasuusta. In inta badan ee qalabka elektarooniga ah loo isticmaalo by baaraandegidda karsado hadda korontada. Habkani wuxuu kuu ogolaanayaa inaad si loo farsameeyo macluumaad badan oo waqti gaaban oo uu leeyahay oo kaliya labo qiyamka - "Haa" ama "Maya". Cutubkan waxa ugu yar waxa loo yaqaan yara wargelin ah.

Iyada oo taageero ka gelinno computer ka dhigay oo dhan loo baahan yahay xog - qoraal, sawir, dhawaaqa iyo wixii la mid ah. Si loo kordhiyo processing xawaaraha garaaca wadnaha, go'aanka waxaa loo sameeyey inay burburto durdur oo dhan kooxo - hal xidhmo oo 8 gelinno ayaa lagu magacaabay byte. Iyadoo horumarinta technology loo baahan yahay in la dhan mugga weyn ee xogta ka shaqeeyaan, sababtoo ah waxa ay bilaabeen inay u muuqdaan qeybinta cusub kooxo waaweyn.

Si loo fududeeyo habka ka mid ah fahamka tiro Siiyey gelinno magnitude, waxaa la go'aamiyay in la isticmaalo horgalaha nidaamka SI ee unugyada. Sidaas darteed, waxaa kilobits, megabytes iyo qiyamka kale ee qadarka xasuusta. Laakiin, sida ay hal SI ah, qiimaha factor kasta horgale ee foomka of 10 ilaa xad. macluumaad computer A, sababta oo ah duality, wakiil qaab laba xoogaa. Taas darteed, go'aanka saxa ah ee magnitude yar waxaa inta badan wajahay khilaaf. In kasta oo ay kala duwan ee hadda jira in go'aanka saxda ah ee tirada jajabka, qiyamka kala duwan ee consoles'ka la farqi yar waa qiimo lahayn. Sayidka, sidaas waxa muujiyay xisaabo kuwan, in 1 kilobyte aan ku jira 1,000 bytes, halka 2 ¹⁰ - 1024 bytes.

Sidee mid gigabyte?

Horgalaha "Giga" ee nidaamka SI ah waa September ^10, ie 1 billion. lifaaqa u dhaw "Giga" - "ahee", taas oo ah 10 ³ jeer ka yar. Laakiin inta badan dunida, oo ay ku jiraan Russia, tirada dhabta ah ee bytes waxaa lagu go'aamiyaa iyadoo la isticmaalayo deuces in degree n-th ah, sidaas jawaabta su'aasha ah ee sida badan MB 1 GB waa 1024.

Sii qiimaha yar, halkii ay ka tarmo by 1000 xisaabaha dheeraad ah la sameeyey iyadoo la isticmaalayo laba 10 degree. Sayidka, GB 1 - waa 1024 * 1024 = 1048576 ama kilobayt 1024 ³ = 1 073 741 824 bytes. Si aad u hesho tirada jajabka ee GB 1, qiimaha helay waa loo laablaabi by 8 bytes, isagoo guud ahaan wax yar ka badan bilyan ah.

Qiimaha ugu weyn ee lacagta ah ee xasuusta

halbeegyada wax lagu cabbiro Qaadirka xusuusta ayaa muddo dheer dhaafay Horgalaha "Giga" ku saabsan heerarka kala duwan. Waqtigan xaadirka ah, qiimaha ugu weyn ee lacagta macluumaadka waa mid ka mid Yottabyte. Marka la barbar dhigo 1GB waa 10 ama ¹⁵ jeer, sida ay qabto qeexidda Ruush, in 20 ^{ilaa 50} jeer.

Inta u dhaxaysa Yottabyte gigabyte iyo 4 waxaa lagu abaabulaa More go'aaminta mugga, mid kasta taas oo yaraynaysa heerka 10s saddex adigoo isticmaalaya nidaamka SI ama, kiiska binary, awood ah laba ilaa 10.

Ki gigabyte - badan ama yar?

Maalin kasta oo adduunka ah ayaa la soo saaray xisaabaha kala duwan, in ay ku kaydiso mugga guud ee taas 1 GB kuma filna. Qiimaha Tani waa dhif ku haboon xitaa hal user - Hadda mugga RAM, oo kaydiya xogta si joogto ah loo isticmaalo, hore u at jeer ka badnaan qiimaha this. size ee filimka in muddo celcelis ahaan ku saabsan saacad ka qaadataa in ka badan gigabyte ah, taas oo ah sababta qadarka xasuusta qiimaha laftiisa ayaa ahaa mid yar, inkastoo muhiimadda weyn markii la tixgelinayo byte by byte.

Ul of 1 GB - waxay sidoo kale waa wax la soo dhaafay, kuwaas oo ay adag tahay in la helo. Haddaba, si ay u gudbiyaan macluumaad la isticmaalayo qalab dheeraad ah oo la asaasay, oo ay ku jiraan drives adag dibadda, mugga oo ay gaari karaan toban terabytes, kaas oo 1000 jeer ka badan gigabytes.
