Cov lus teb luv luv yog yog rau niaj hnub kev ua si . Feem ntau cov neeg ua haujlwm lossis ob txoj xov ntxiv rau qee yam haujlwm. Kuj muaj nodifferentiation ntawm kev ua si thiab lwm yam kev pab cuam. Multi-threading txhais tau hais tias qhov kev zov me nyuam yog sib npaug, lossis nws yuav tsum ua ntau yam kev ywj pheej nyob rau tib lub sijhawm.
Yog li ntawd, multithreading puas txhim kho kev ua si?
Multi threading txhim kho kev ua haujlwm los ntawm kev tso cai rau ntau lub CPUs ua haujlwm ntawm qhov teeb meem tib lub sijhawm; tab sis nws tsuas pab yog tias ob yam muaj tseeb: ntev npaum li CPU ceev yog qhov limiting factor (as opposed to memory, disk, or networkbandwidth) THIAB ntev li ntev tau multithreading tsis qhia ntau yam haujlwm ntxiv (aka
Kuj Paub, threads lossis cores puas zoo dua rau kev ua si? Cores vs Xov Thaum twg Gaming Cores yuav ib txwm tseem ceeb dua thaum kev ua si . Txawm niaj hnub kev ua si tuaj yeem khiav tau yooj yim ntawm aquad- tub ntxhais , 4- xov CPU, nyob ntawm tus processor lub cache thiab moos ceev. Xov yeej siv tau thaum koj tab tom khiav ntau yam haujlwm. Hais tias koj yog kev ua si thiab koj npaj rau streaming.
Ib sab saum toj no, cov kev ua si puas tau txais txiaj ntsig los ntawm ntau cov cores?
Multi-Core CPU Kev ua si Kev ua tau zoo Ntau thiab ntau ua si Tam sim no tuaj yeem tau txais txiaj ntsig zoo ntawm cov tub ntxhais siab / xov suav muaj nrog CPUs niaj hnub, yog li ua rau pom kev ua tau zoo dua nrog cov txheej txheem uas muaj 4 lossis ntau cores.
Vim li cas kev ua si tsis siv ntau lub cores?
Yog vim li cas ua si tsis siv ntau ntawm cores yog vim nws yuav siv sij hawm ntau ntawm cov hauj lwm ntxiv kom tau ntau threads khiav nyob rau hauv parallel flawlessly. Bingo. Qhov ntawd yog vim nws yog lub processor qeeb nrog lub moos qis, tsis yog vim nws muaj tsawg cores.

Dab tsi ntawm cov hauv qab no yog qhov zoo ntawm kev siv cov khoom siv pom kev hauv kev hais lus?
Qhov txiaj ntsig tseem ceeb ntawm kev siv cov khoom siv pom hauv koj cov lus hais yog tias lawv ua kom cov neeg tuaj saib muaj kev txaus siab, hloov kev mloog ntawm tus neeg hais lus, thiab ua rau tus neeg hais lus muaj kev ntseeg siab ntau dua hauv kev nthuav qhia tag nrho
Dab tsi yog qhov txawv ntawm cov neeg siv kev paub thiab kev paub ntawm cov neeg siv khoom?
User Experience (UX) cuam tshuam nrog tib neeg cuam tshuam nrog koj cov khoom thiab cov kev paub uas lawv tau txais los ntawm kev sib cuam tshuam. Customer Experience (CX), incontrast, encompasses tag nrho cov kev sib cuam tshuam ib tug neeg muaj nrog koj hom
Puas txhais tau tias yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas muab cov lus qhia rau kev siv cov khoom?
Kev them nyiaj yog kev sib raug zoo ntawm cov khoom ntawm ib yam khoom thiab lub peev xwm ntawm tus neeg sawv cev uas txiav txim siab seb qhov khoom siv tau li cas
Cov kev pabcuam lossis cov txheej txheem twg uas Secure Copy Protocol vam khom kom ntseeg tau tias kev hloov pauv kev nyab xeeb yog los ntawm cov neeg siv tau tso cai?
Cov kev pabcuam lossis cov txheej txheem twg uas Secure Copy Protocol vam khom kom ntseeg tau tias kev hloov pauv kev nyab xeeb yog los ntawm cov neeg siv tau tso cai? Secure Copy Protocol (SCP) yog siv los luam cov duab IOS kom ruaj ntseg thiab teeb tsa cov ntaub ntawv mus rau SCP server. Txhawm rau ua qhov no, SCP yuav siv SSH kev sib txuas los ntawm cov neeg siv uas tau lees paub los ntawm AAA
