Multithreaded applications yog cov uas siv lub tswv yim ntawm Concurrency piv txwv li lawv muaj peev xwm ua tau ntau tshaj li ib txoj hauj lwm nyob rau hauv parallel. Ib qho piv txwv yooj yim yuav yog aword-cov ntaub ntawv uas, spell-check, teb rau keyboard, formatting thiab lwm yam tshwm sim nyob rau tib lub sij hawm los yogConcurrently.
Ib yam li ntawd, tib neeg nug, dab tsi yog qee qhov kev siv ntau threaded?
Qee cov ntawv thov multithreaded yuav yog:
- Web Browsers - Ib lub web browser tuaj yeem rub tawm ib tus lej ntawm cov ntaub ntawv thiab nplooj ntawv web (ntau tabs) tib lub sijhawm thiab tseem cia koj mus txuas ntxiv mus.
- Web Servers - Ib lub web servers ua haujlwm txhua qhov kev thov nrog cov xov tshiab.
Tsis tas li ntawd, dab tsi yog multi threaded ib puag ncig? Hauv computer architecture, multithreading yog qhov muaj peev xwm ntawm lub hauv paus ua haujlwm (CPU) (lossis ib qho tseem ceeb hauv a ntau -core processor) muab ntau threads ofexecution concurrently, txhawb los ntawm lub operating system.
Tom qab ntawd, lo lus nug yog, dab tsi yog ib txoj haujlwm multi threaded?
Ntau - threaded programs khiav zoo dua thiab siv cov peev txheej tsawg dua li ib qhov kev pab cuam uas tsim ntau cov txheej txheem kom ua tiav tib txoj haujlwm. Threads qhia thoob ntiaj teb cov ntaub ntawv thiab lwm yam kev pabcuam, tab sis txhua txoj xov muaj nws tus kheej lub tshuab ua haujlwm thiab pawg rau cov ntaub ntawv uas nyob hauv zos rau txhua qhov haujlwm hauv qhov kev pab cuam.
Puas yog PHP ib leeg threaded?
2 Teb. Cov ib threaded xwm ntawm PHP txhais tau tias PHP tsis muaj ib qho built-in txhawb rau spawning tshiab threads thaum sau ntawv. Txawm li cas los xij, qhov no tsis tau txhais hais tias koj tsis tuaj yeem muaj ob qhov kev ua tiav ntawm tib daim ntawv ib txhij. Hauv kev teeb tsa ntau tshaj plaws, koj lub vev xaib tau txais kev pabcuam los ntawm Apache
Pom zoo:
Dab tsi ntawm cov hauv qab no yog hais txog cov txheej txheem ntawm tus kheej muaj cov kev pabcuam uas sib txuas lus los tsim ib daim ntawv thov software ua haujlwm?
Ib qho kev pabcuam-oriented architecture yog teeb tsa cov kev pabcuam tus kheej uas sib txuas lus nrog ib leeg los tsim ib daim ntawv thov software ua haujlwm. Nyob rau hauv ib tug ntau-tiered network: kev ua hauj lwm ntawm tag nrho cov network yog sib npaug ntawm ntau theem ntawm servers
Thaum cov lus tau hla tawm cov ntaub ntawv kuaj xyuas feem ntau nthuav tawm cov ntawv sau thawj nrog kev pab ntawm dab tsi?
Infrared luminescence yog siv rau: Qhia tawm cov ntawv sau uas tau muab tshem tawm THIAB kuaj pom yog tias ob tus lej sib txawv tau siv rau hauv kev sau ntawv. Cov kws tshuaj xyuas cov ntaub ntawv feem ntau nthuav tawm cov ntawv sau thawj ntawm cov lus uas tau hla nrog kev pab ntawm: Infrared tawg
Dab tsi VM Series koj yuav tsum xav txog yog tias koj xav tau cov ntawv thov host uas xav tau kev ua haujlwm siab IO rau cov ntaub ntawv tsis tu ncua?
Teb: VM series uas koj yuav tsum yog xav txog yog tias koj xav tau txais cov ntawv thov uas xav tau kev ua haujlwm siab rau cov ntaub ntawv tsis tu ncua yog VMware workstation, Oracle VM virtual box lossis Microsoft Azure suav. Cov khoom siv no muaj qhov yooj yim tshaj plaws ntawm kev ua haujlwm hosting
Dab tsi yog cov khoom tsim nyog los tsim cov ntawv thov Web?
Cov khoom siv hauv web-based applications. Txhua qhov web-based database applications muaj peb yam tseem ceeb: Ib lub web browser (lossis tus neeg siv), lub web application server, thiab database server
Txoj hauv kev zoo tshaj plaws rau daim ntawv thov upload cov ntaub ntawv loj hauv s3 yog dab tsi?
Cov ntaub ntawv loj tshaj plaws uas tuaj yeem muab tso rau hauv Amazon S3 thoob hauv ib qho kev ua haujlwm PUT yog 5 GB. Yog tias koj xav upload cov khoom loj (> 5 GB), koj yuav txiav txim siab siv multipart upload API, uas tso cai rau upload cov khoom ntawm 5 MB mus txog 5 TB
