Kodi KBs angati mu MB kapena GB? Dziwani kuti kompyuta yanu ili ndi ndalama zingati.
Ngati mumasokonezeka ndi momwe makompyuta anu amasungira ndi kusungirako, ndipo mukudodometsedwa ndi KBs, MBs, ndi GB, sizosadabwitsa. Pali ziphwando zambiri polemba, ndipo nthawi zina zimasokoneza manambala omwe akugwirizanako nawo.
Pali njira ziwiri zofotokozera malo osungirako komanso kukumbukira kompyuta yanu. Ichi ndifotokozera mosavuta zomwe zikuchitika, koma ngati simukufuna masamu kumbuyo kwa yankho lanu, mukhoza kudumpha molunjika mpaka kumapeto.
Kumvetsetsa Binary vs. Numimal Numbers
Choyamba, phunziro lachidule la masamu. Timachita masamu athu a tsiku ndi tsiku mu dongosolo la decimal. Dipatimenti ya decimal imakhala ndi majhumi khumi (0-9) omwe timagwiritsa ntchito kufotokoza manambala athu onse. Makompyuta, chifukwa cha zovuta zawo zonse, amatha kukhala ndi mawolo awiri okha, 0 ndi 1 omwe amaimira zigawo za magetsi.
Izi zimatchulidwa ngati ndondomeko yamabina, ndipo zingwe za zeros ndi zina zimagwiritsidwa ntchito kufotokozera ziwerengero. Mwachitsanzo, kuti mufike ku nambala ya decimal 4 mu binary mungathe kuwerenga monga: 00,01,10,11. Ngati mukufuna kupita pamwamba kuposa izo, mukusowa ma chiwerengero.
Kodi Bits ndi Zolemba Zotani?
Pang'ono ndi pang'ono kakang'ono kosungirako pa kompyuta. Tangoganizani pang'ono kali ngati babu. Yoyamba iliyonse imatha kapena imachoka, choncho ikhoza kukhala imodzi mwazinthu ziwiri (0 kapena 1).
Chiwonongeko ndi chingwe cha mipiringidzo eyiti (mababu asanu ndi atatu mzere). Kawirikawiri ndi gawo lochepa kwambiri la deta limene lingagwiritsidwe ntchito pa kompyuta yanu. Momwemo, malo osungirako nthawi zonse amayesedwa mwa bytes osati mabito. Mtengo wamtengo wapatali kwambiri umene ungaimiridwe ndi ojambula ndi 2 8 (2 x 2 x 2 x 2 x 2 x 2 x2 x2) kapena 256.
Kuti mudziwe zambiri pa nambala yachinyamata, kuphatikizapo momwe mungawasinthire mpaka madimita, chonde onani malo omwe ali ndi zowonjezera pansipa.
Kilobyte (KB) muzinthu zowonongeka ndi 1024 bytes (2 10 ). Chizindikiro cha "kilo" chimatanthauza chikwi; Komabe, mu kilobyte (1024) yochepa kwambiri ndi yaikulu kwambiri kuposa decimal definition (1,000). Apa ndi pamene zinthu zimayamba kusokoneza!
Megabyte mu binary ndi 1,048,576 (byteste) 20 . Mu decimal ndi 1,000,000 bytes (10 6 ).
Gigabyte ndi 2 30 (1,073,741,824) bytes kapena 10 9 (1 biliyoni bytes). Panthawi imeneyi, kusiyana pakati pa kanema ndi kanthini kumakhala kofunika kwambiri.
Kotero Ndili Ndi Chikumbu Chotani Ndili Ndili Ndili?
Chifukwa chachikulu chimene anthu amasokonezeka ndi chakuti nthawi zina opanga amapereka chidziwitso mu decimal ndipo nthawizina amapereka izo muzowona.
Ma drive ovuta, magalimoto oyendetsa, ndi zipangizo zina zosungirako nthawi zambiri amafotokozedwa mu decimal kuti zikhale zosavuta (makamaka pamene akugulitsa kwa wogula). Kumbukumbu (monga RAM) ndi maofesi nthawi zambiri zimapereka zoyenera.
Popeza 1GB mu binary ndi yaikulu kuposa 1GB mu decimal, tonsefe nthawi zambiri timasokonezeka chifukwa cha malo omwe tikupeza / kugwiritsa ntchito. Ndipo choipa kwambiri, kompyutala yanu ikhoza kunena kuti ili ndi 80GB hard drive, koma njira yanu yogwiritsira ntchito (yomwe imalemba mu binary!) Idzakuuzani kuti ndizochepa (pafupifupi 7-8 GB).
Njira yosavuta yothetsera vutoli ndi kungonyalanyaza momwe mungathere. Mukagula chipangizo chosungirako, kumbukirani kuti mukuchepa pang'ono kuposa momwe mumaganizira ndikukonzekera. Kwenikweni, ngati muli ndi GB 100 mu maofesi kuti musunge kapena mapulogalamu, mufunika hard drive ndi malo okwana 110 GB.
