Njani oku kuba ngohlobo umbandela, umzekelo, iincwadi efanayo? Ngapha koko, ubukhulu iincwadi okwangoku ngokucacileyo zimele. Makhe sizame ukwenza izibalo kwaye uphendule lo mbuzo. Oku kucingwa ukuba kwiphepha lokubhaliweyo iqulethe abalinganiswa 2500. Ngoko ke, incwadi kwiphepha 400 iqulethe 1 megabytes lwe data. Koko ubukhulu ilayibrari omnye gigabyte kuya kufuneka ziqulathe iincwadi 1024. Phinda ubungakanani aziwayo, sifumana iincwadi ezingaphezulu kwezigidi. Thelekisa, ingxowa-mali yeyona idumileyo kweli lizwe uLenin Library malunga nezigidi ezingama-50 iikopi. Iyonke, siye phantse 22 ezinjalo amathala iqokelelwe petabyte mnye.

Cisco Sistems Statistics usinika ithuba lokuba bajonge kula manani, yaye mihle. Iziza e-mail kwezithuthi ze Web bungama-260 PB ngosuku, ngexesha xa ingqondo yomntu ungagcina PB 1 kuphela bonke ubomi phantsi kweemeko ezifanelekileyo.

Kusenza sicinge ukuba benze ntoni na ezi omkhulu kolwazi njengoko kusetyenzwa, kwaye isebenza njani ukushiya izizukulwana zexesha elizayo memory endilisekileyo yale ubudala revolution computer.
