Yini inqubo encane kakhulu yomlayezo?

Ngemuva, ekubaleni, amabithi yizakhiwo eziyisisekelo zokwenza isenzo. Ngokwamlando, amabithi ayisishiyagalombili aqondiswa kubhayithi, okuyinto yinqubo encane kakhulu yomlayezo noma imemori.

Yini inqubo encane kakhulu nasekukhuleni kwe-data?

Yini usayizi omkhulu wedatha?

“Idatha enkulu” yisipiliyoni esihlobene nokwamandla okubalwa nokugcinwa kwamandla okuthengiswa — ngakho ngo-1999, igigabhayithi elilodwa (1 GB) bekulokhu kubhekwa njenge-data enkulu. Namuhla, kungaba izipetabhayithi (1,024 ama-terabyte) noma ama-exabyte (1,024 amapetabyte) yomlayezo, okuhlanganisa amabhiliyoni noma nezinkulungwane zezingane ezimiliyoni zabantu.

Yini ukulinganisela kwedatha enkulu?

Ngenkathi idatha yezakhiwo ezijwayelekile iqondiswa ngosayizi wokwaziyo njenge-megabytes, ama-gigabytes kanye ne-terabytes, idatha enkulu igcinwa kuma-petabytes ne-zettabytes.

Ukulungiswa kwedatha kuhlolwa kanjani?

Ukulungiswa kwekhompyutha nokukhumbula kuvakasha ngokuningi kuhlolwa ngama-megabyte (MB) nama-gigabyte (GB). Incwadi ephakathi ngesikhathi eside inesiqophelo sika-1 MB lwemibhalo. 1 MB yile-1,024 kilobyte, noma 1,048,576 (1024×1024) amabyte, hhayi amayunithi ayisigidi. Njalo, 1 GB yile-1,024 MB, noma 1,073,741,824 (1024x1024x1024) amabyte.

Ingabe yini eyayibizwa ngesigaba se-byte?

Ekukhumbuleni nokuthuthukiseni izinto ezilandelana, inibble yile-4 amakhulu amadigitali noma isigaba se-8-bit byte. Uma kubhekwa i-byte, kungenzeka kube yile-4 amakhulu okuqala noma okugcina, yilokho okwenza inibble ibizwe ngesigaba se-byte.

Yiziphi izinhlobo ezintathu zokugcina?

Kusho ukuthini 1 GB yedatha?

Yini i-GB? I-GB (gigabyte) yindlela yokuhlola ukuthi unawo amadatha angakanani kwidivayisi yezinto zokuthutha. 1GB yile-1,000MB (megabyte). Inani le-GBs olinawo kwi-SIM yakho likunika ukuthi unawo amadatha angakanani wezibhakabhaka ngamunye.

Amagigabyte angaphi angadatha?

Igigabyte yindlela ethize yokuhlolwa kwedatha okulingana namayunithi ayizigidi zedatha. Igama le-gigabyte lizetshenziswa kakhulu ukuchaza inani lezinto ezilondoloziwe noma ukwakheka kwedivayisi yokugcina. Isibonelo, i-HDD inganikeza amagigabyte angu-500 wekhawunta elikhulu kodwa okwamanje igcina amagigabyte angu-200 wedatha.
