Memory vanokwanisa 1 GB - ndiwo sei?

With kukura zvigadzirwa kombiyuta pane mashoko matsva ose gore. Kazhinji vanhu vanoshandisa shoko "gigabyte", asi haana kunyatsonzwisisa kukosha pfungwa iyi, nokuti chii haagoni kupindura mubvunzo pamusoro uwandu ndangariro 1 GB - ndiwo sei.

Chii chinonzi gigabyte?

Tisati kubata mubvunzo "1GB - zvizhinji kana zvishoma," unofanira kunzwisisa musimboti kuyeuka chimwe. In vakawanda dzinoshandiswa processing zvemagetsi iyezvino pulses zvemagetsi. Nzira iyi inobvumira kuti ribude zvakawanda munguva pfupi uye ane tsika mbiri chete - "Hongu" kana "Kwete". Ichi chikwata pasipasi inonzi anodzidzisa wedzeredzei.

Achibatsirwa matomu kombiyuta wakaiswa zvose zvakafanira Data - chinyorwa, mifananidzo, inzwi uye zvichingodaro. Kuwedzera nokukurumidza kupomba kubudiswa, chisarudzo chakaitwa kuti aputse rukova rose muzvikwata - imwe iine 8 matomu dzainzi byte. With kukura zvigadzirwa vaifanira kushanda vose guru Vhoriyamu data, nokuti chii akatanga kuonekwa nokupesana itsva mumapoka makuru.

Kurerutsa muitiro kunzwisisa rakapihwa nhamba matomu unokosha, kwakasarudzwa kushandisa chivakashure of SI ezvinhu dzakabatana. Somugumisiro, pane kilobits, megabytes uye dzimwe tsika uwandu ndangariro. Asi, maererano chete SI, kukosha neimwe chinhu aiva chivakashure muchimiro 10 kusvika. A ruzivo kombiyuta, nokuda kwayo duality, aimiririra muchimiro maviri zvishoma. Nokuda kwaizvozvi, kutsunga yakarurama vaduku zvikuru vanowanzotambura atarisana kusawirirana. Pasinei huripo kusiyana chaiyo kutsunga nhamba matomu, tsika yacho kusiyana nokuda inonyaradza ine musiyano muduku vasingakoshi. Saka, maererano Masvomhu izvi, muna 1 kilobyte asina mabhati 1,000 BYTES, apo 2 ¹⁰ - 1024 bytes.

Sei imwe gigabyte?

The chivakashure "giga" nokuti ari SI maitiro ari September ^10, kureva 1 bhiriyoni. Pedyo kutyira "giga" - "Mega", inova 10 ³ nguva duku. Asi akawanda munyika, kusanganisira Russia, nhamba chaiyo bytes kunotemwa nokushandisa deuces vari N-fung dhigirii, saka mhinduro yomubvunzo wokuti sei MB zhinji 1 GB ndiye 1024.

Kuramba nemararamiro diki, pane kuwedzera 1000 mimwe Masvomhu dzinoitwa kushandisa maviri 10 dhigirii. Saka, GB 1 - ndiko 1024 * 1024 = 1048576 kana kilobytes 1024 ³ = 1 073 741 824 bytes. Kuti tiwane nhamba matomu GB 1, mutengo vakawana inofanira kane 8 BYTES, une dzinosvika zvishoma anopfuura bhiriyoni.

Kunokosha zvikuru uwandu ndangariro

Mutongi kuyerwa vamapoka ndangariro kare Munopfuura chivakashure "giga" dzakasiyana siyana. Panguva iyoyo, kunokosha zvikuru uwandu mashoko ndomumwe Yottabyte. Tichienzanisa 1GB ndiyo 10 kana ¹⁵ nguva, maererano Russian tsananguro, muna 20 ^{kusvika ka50.}

Pakati Yottabyte gigabyte uye 4 vari akaronga More kuziva vhoriyamu, chimwe nechimwe kunoderedza dhigirii 10s kupinda matatu achishandisa SI nehurongwa kana, mune binary nyaya, mumwe simba maviri 10.

Gigabyte - chaizvo kana zvishoma?

zuva ose munyika anobudiswa Masvomhu siyana, kuti achengetere zvachose vhoriyamu izvo 1 GB hakuna kukwana. ukoshi ino haisi vakakodzera kunyange mumwe User - Zvino RAM vhoriyamu, iro rinochengeta aiwanzotaura data, kare dzimwe nguva kupfuura kukosha ichi. Kukura firimu iri neavhareji ya inenge awa anotora chete pamusoro gigabyte, ndokusaka chitsama ndangariro mutengo pachayo yakanga zviduku, pasinei guru kukosha kana tichifunga byte kubudikidza byte.

Rutanda 1 GB - zviri zvakare chinhu chekare, chiri nyore kuwana. Zvino, uchatamisa mashoko kushandisa voluminous mano, kusanganisira zvokunze dzakaoma Zvifambiso, bhuku zvinogona kusvika terabytes gumi, riri zvakawanda gigabytes 1000 nguva.
