Tanthauzo la Nthawi Yofunafuna Hard Drive
Nthawi yofufuza ndi nthawi yomwe imatengera gawo lapadera la makina a hardware kuti apeze chidutswa china cha chidziwitso pa chipangizo chosungirako. Mtengo umenewu umapezeka milliseconds (ms), pomwe mtengo wochepa umawonetsa nthawi yofunafuna mofulumira.
Kodi ndi nthawi yanji yomwe simukufuna nthawi yonse yomwe imatengera kukopera fayilo ku galimoto ina, kulandila deta kuchokera pa intaneti, kuwotcha chinachake ku diski, ndi zina zotero. Ngakhale nthawi yofunira imakhala nayo nthawi yonse yomwe imatenga nthawi Kuti akwaniritse ntchito ngati izi, zimakhala zosasamala poyerekeza ndi zina.
Funani nthawi nthawi zambiri amatchedwa nthawi yowonjezera , koma kwenikweni nthawi yowonjezeramo ikukhala yayitali kuposa nthawi yopeza chifukwa pali nthawi yaying'ono yophatikizapo pakati pa kupeza deta ndikuyipeza.
N'chiyani Chimafuna Kusankha Nthawi?
Nthawi yofunafuna galimoto yolimba ndi nthawi yomwe imatengera msonkhano wa mutu wa hard drive (omwe amawerengera kuwerenga / kulemba deta) kuti akhale ndi dzanja lake lokonzekera (komwe mitu ilipo). deta ikusungidwa) kuti muwerenge / kulemba deta ku gawo lina la disk.
Popeza kusuntha mkono wogwiritsira ntchito ndi ntchito yomwe imatenga nthaŵi kuti ikwaniritse, nthawi yowonjezera ikhoza kukhala pafupi nthawi yomweyo ngati mutu uli kale kale, kapena ndithu ngati mutu ukuyenera kupita kumalo osiyana.
Choncho, nthawi yofufuza ya hard drive imayesedwa ndi nthawi yake yofunafuna nthawi yomwe sikuti magalimoto onse ovuta nthawi zonse amakhala nawo pamsonkhano womwewo. Nthaŵi yofunira kawirikawiri ya magalimoto imakhala yowerengeka poyerekeza ndi nthawi yomwe imatengera kuyang'ana deta pamwamba pa gawo limodzi la nyimbo za hard drive.
Langizo: Onani tsamba 9 la PDFyi kuchokera ku webusaiti ya University of Wisconsin kuti mudziwe zambiri zokhudza masamu pofufuza nthawi yofunira.
Ngakhale kuti nthawi yochuluka yofunafuna ndiyo njira yowonjezera yowunikira phinduli, ikhoza kuchitidwa m'njira zinanso ziwiri: kujambulira ndi kufufuza . Kuwongolera pulogalamu ndi nthawi yomwe imatengera kufufuza deta pakati pa miyeso iwiri yoyandikana, pamene kulira kwazomwe kuli nthawi yomwe imatenga nthawi kuti mufufuze kutalika kwa diski, kuchokera mkatikati mpaka kumtunda.
Zida zina zosungiramo katundu zimakhala ndi zoyendetsa zovuta zomwe zimakhala zochepa kwambiri pamtunda kotero kuti pali zocheperapo, kenako kulola woyendetsa mtunda wamfupi kuti ayende pamsewu. Izi zimatchedwa " short stroking" .
Malembo ovuta awa angakhale osadziwika ndi osokoneza kuti atsatire, koma zonse zomwe mukufunikira kudziwa ndi kuti nthawi yowunikira galimoto yochuluka ndi nthawi yomwe imatengera kuyendetsa kupeza deta yomwe ikuyang'ana, choncho mtengo wochepa imayimira nthawi yofufuza mofulumira kuposa yaikulu.
Fufuzani Zitsanzo za Nthawi Zomwe Zimagwiritsidwa Ntchito
Ambiri mwafuna nthawi ya ma drive oyendetsa akhala akupita pang'onopang'ono pakapita nthawi, ndipo oyamba (IBM 305) ali ndi nthawi yofuna pafupifupi 600 ms. Patatha zaka makumi angapo, anapeza nthawi yofuna HDD kukhala pafupi 25 ms. Ma driving hard drives angakhale ndi nthawi yozungulira 9 ms, zipangizo zamakono 12 ms, ndi ma seva otsiriza okhala ndi 4 ms nthawi yofunafuna.
Ma drive ovuta olimba (SSDs) alibe magawo osunthira ngati ma drive oyendetsa, kotero nthawi zawo zofuna zimayesedwa mosiyana, ndi SSD ambiri ali ndi nthawi yofuna pakati pa 0.08 ndi 0.16 ms.
Zina za hardware, monga diski disk drive ndi floppy disk drive , kukhala ndi mutu waukulu kuposa hard drive ndipo kotero pang'onopang'ono kufunafuna nthawi. Mwachitsanzo, ma DVD ndi ma CD amakhala ndi nthawi yofunira pakati pa 65 ms ndi 75 ms, yomwe ndi yocheperapo kusiyana ndi ya ma drive ovuta.
Kodi Kufunafuna Nthawi Ndikofunika Kwambiri?
Ndikofunika kuzindikira kuti ngakhale nthawi yofuna imakhala yofunikira pozindikira nthawi yonse ya makompyuta kapena chipangizo china, palinso zigawo zina zomwe zimagwira ntchito mofanana ndi zofanana.
Kotero ngati mukuyang'ana kuti mupeze galimoto yatsopano yofulumizitsa kompyuta yanu, kapena kuyerekezera zipangizo zingapo kuti muone kuti ndi yiti yomwe ikufulumira kwambiri, kumbukirani kuganizira zinthu zina monga dongosolo lakumbuyo , CPU , mafayilo , ndi mapulogalamu omwe akugwira ntchito chipangizochi.
Mwachitsanzo, nthawi yonse yomwe imatengera kuchita monga kukopera kanema kuchokera pa intaneti, ilibe nthawi yochuluka yochitira ndi nthawi yowunikira. Ngakhale ziri zoona kuti nthawi yosunga fayilo ku diski imakhala yeniyeni pa nthawi yofunira, popeza kuti galimoto yovuta siigwira ntchito panthawi yomweyo, pamtundu woterewu pamene mukutsitsa mafayilo, liwiro lonse limakhudzidwa ndi mawonekedwe a makanema.
Lingaliro lomwelo likugwiranso ntchito pazinthu zina zomwe mukuchita monga kutembenuza mafayilo , kudula DVD ku hard drive, ndi ntchito zofanana.
Kodi Mungawongolere Nthawi Yowonjezera ya HDD & # 39; s?
Ngakhale simungathe kuchita chilichonse kuti muthamangitse katundu wa hard drive kuti muwonjezere nthawi yake yofunafuna, palinso zinthu zomwe mungachite kuti mukhale ndi ntchito yabwino. Izi ndi chifukwa chakuti nthawi yodzifunira yokhayo siyi yokhayo yomwe imapanga ntchito.
Chitsanzo chimodzi ndi kuchepetsa kugawanika pogwiritsira ntchito chida cha ufulu cha defrag . Ngati zidutswa za fayilo zimafalikira zonse za hard drive muzipinda zosiyana, zidzatenga nthawi yochuluka kuti galimoto yowononga ikhale yosakaniza. Kuponderezedwa kwa galimoto kungagwirizanitse maofesi amenewa kuti apititse patsogolo nthawi yofikira.
Musanapunthwitse, mungaganize kuchotsa mafayilo osagwiritsidwa ntchito monga tsamba losatsegulira, kuchotsa Recycle Bin, kapena kusungitsa deta yomwe sagwiritsire ntchito ntchitoyo, mwina ndi chida chosungira chomasulidwa kapena utumiki wachinsinsi . Mwanjira imeneyo, galimoto yovuta sichiyenera kufotokoza deta yonse nthawi iliyonse yomwe imafunika kuwerenga kapena kulemba chinachake pa diski.
