PB - kangakanani ulwazi?

Ukuze uthole bezibona olunembile ngaphandle abantu emhlabeni necebo uhlelo nesilinganiso. Safunda indlela yokukala isisindo, speed, ubude, kanye nezinye izici. Ukuthuthukiswa lobuchwepheshe be-computer kuye kwaholela ukuba sicabangele nolwazi. Manje inombolo yakhe lase likhule kakhulu kangangokuba i nesilinganiso ivolumu kuyadingeka iyunithi efana petabyte. Kungakanani kuba, futhi sizozama ukuqonda.

PB - kangakanani lokhu?

Ukuze siphendule lo mbuzo ake nje uchaze ukuthi sikhuluma inani Imininingwane kusetshenzwe noma agcinwe. Kakhulu esetshenziswa esikhathini sethu isibe iyunithi gigabytes.

Usayizi kwisitoreji semidiya ngokomzimba ezifana flash oshayelayo nama-hard drive lwamakhompyutha wabonisa kulezi amayunithi. Ngakho-ke, umbuzo ilungile ngabe ufunde kanje: "Petabyte, yindlela gigabytes eziningi idatha?". Bangamaphesenti kunalokho enkulu yalo GB 1048576 noma 1024 TB (terabytes).

Ulwazi ivolumu ngokomzimba

Lesi sibalo okuholela gigabytes Yiqiniso, iyamangalisa ngisho unika ukumelwa ezinye izinsiza ezibonwayo, kodwa noma kunjalo ubukeka ngendlela yazo esabalele. Yileyo indlela kubantu akwenzayo kudingeka okuthile ukuqhathanisa, ukuqonda kanye nokwethula ongaboni. Ngokulinganayo, ke singasho sithi inani Imininingwane kufakwe PB.

Kanjani lokhu kungaba ngesimo indaba, isibonelo, izincwadi ezifanayo? Phela, ubukhulu amabhuku njengamanje ngokucacile amelela. Ake sizame ukwenza izibalo kanye ukuphendula lo mbuzo. Kuthathwa ngokuthi ikhasi mbhalo uqukethe izinhlamvu 2500. Ngakho, encwadini Amakhasi 400 iqukethe 1 wamamegabhayithi idatha. Khona-ke omunye igigabhaythi usayizi umtapo uzodinga aqukethe amabhuku 1024. Ukuphindaphinda nenani ezaziwayo, sithola izincwadi ezingaphezu kwezigidi eziyinkulungwane. Ukuze uqhathanise, lesi sikhwama futhi elalidume kunawo wonke kuleli zwe Lenin Library amakhophi ayizigidi ezingaba ngu-50. Ubude, sinalo cishe 22 imitapo enjalo eqoqwe kwelinye petabyte.

Singakanani ngeke phezu kulezo zindawo ezazihlala ama isikhala? isitoreji endaweni ye-Library of 8.5 ha. Amabili nambili izakhiwo ezinjalo hlala endaweni 187 amahektha umhlaba. Kuyinto ifaniswe ubukhulu of Monaco, okuyinto ethatha amahektha 202 kuphela.

Inani ukwaziswa okukuyi-Internet

Manje, lapho siveza lokho futhi kungakanani petabyte ulwazi imali esilinganisekayo ngokomzimba, singenza kakade ukucabanga afanayo kuzocutshungulwa inethiwekhi Imininingwane Inthanethi.

Cisco Sistems Izibalo kusinikeza ithuba ukubheka lezi zinombolo, futhi umxhwele. Inani le-imeyili traffic futhi Web sites kuyinto 260 PB ngosuku, ngesikhathi lapho ubuchopho bomuntu ingagcina PB 1 kuphela konke ukuphila ngaphansi kwezimo ezifanele.

It lisenza sicabange ngayo lokho okufanele ukwenze lokhu kugeleza omkhulu lwazi njengoba kusetshenzwe, futhi kanjani ukusebenzisa ukushiya izizukulwane ezizayo memory ehloniphekile walonyaka inguquko ikhompyutha.
