Qhov Tseem Ceeb Qhov txawv - Multithreading vs Multitasking

Multithreading thiab Multitasking zoo sib xws tab sis lawv yog ob lub ntsiab lus sib txawv. Lub computer ua ntau yam haujlwm ib txhij. Multithreading thiab Multitasking ob leeg cuam tshuam rau kev ua haujlwm hauv computer. Qhov tseem ceeb sib txawv ntawm multithreading thiab multitasking yog tias nyob rau hauv multithreading, ntau threads yog executing nyob rau hauv ib tug txheej txheem concurrently thiab, nyob rau hauv multitasking, ntau txheej txheem yog khiav concurrently. Kab lus no tham txog qhov sib txawv ntawm multithreading thiab multitasking.

Dab tsi yog Multithreading?

Ib lub khoos phis tawj ua haujlwm ntau ib txhij. Ib txoj haujlwm tuaj yeem paub tias yog txheej txheem. Nws yog ib qho program hauv kev ua tiav. Tsim cov txheej txheem rau txhua txoj haujlwm tsis zoo. Nws tuaj yeem siv ntau yam khoom siv. Txhawm rau zam qhov ntawd, cov txheej txheem tuaj yeem muab faib ua ntau yam txheej txheem thiab cov dej num tuaj yeem ua tiav siv cov txheej txheem ua haujlwm. Ib txheej txheej txheem yog ib chav tsev ntawm txheej txheem. Lub tsev ntawd hu ua xov. Hauv multithreading, tus txheej txheem tau muab faib ua ntau cov xov thiab cov xov no tau ua tiav tib lub sijhawm.

Muaj ob hom kev siv xov tooj hu ua, ib daim ntawv thov threaded thiab ntau daim ntawv thov. Thaum muaj ib tug xov nyob rau hauv ib tug txheej txheem, uas yog hu ua ib threaded thiab thaum ntau threads khiav nyob rau hauv tus txheej txheem, nws yog hu ua multithreaded daim ntawv thov. Multithreading yog qhov muaj txiaj ntsig los ua haujlwm ntau yam haujlwm tib lub sijhawm. Cov piv txwv hauv qab no qhia txog txheej txheem multithreaded. T1, T2, T3 yog threads.

Xov tseem tuaj yeem faib ua ob hom. Lawv yog cov neeg siv xov thiab Kernel xov. Lub Kernel tsis txhawb cov neeg siv xov. Kernel threads tau txais kev txhawb nqa thiab tswj hwm los ntawm kernel. Muaj peb hom Multithreading. Muaj lub npe hu ua Many-To-One model, One-To-One model, and Many-To-Nyob model. Cov duab hauv qab no qhia txog cov qauv threading. 'U' txhais tau hais tias tus neeg siv xov thiab 'K' qhia txog cov xov xov.

Muaj-rau-ib tus qauv

Nyob rau hauv Ntau-rau-Ib tus qauv, ntau tus neeg siv cov xov yog mapped rau hauv ib leeg xov.

ib-rau-ib tus qauv

Nyob rau hauv ib tug mus rau ib tug qauv, txhua tus neeg siv xov yog mapped rau ib tug nyias kernel xov.

Ntau-rau-ntau tus qauv

Nyob hauv ntau tus qauv, multiplexes ntau tus neeg siv-theem xov rau me me los yog sib npaug ntawm cov xov xov.

Multithreading muab ntau yam zoo. Cov xov muaj txiaj ntsig zoo hauv kev sib txuas lus sib txuas. Lawv kuj txhim kho kev teb. Nws tsis yog tsim nyog los faib cov peev txheej rau txhua txoj xov sib cais yog li, siv cov xov yog kev lag luam. Yog tias ib txoj xov tsis ua haujlwm, qhov ntawd yuav tsis cuam tshuam rau tag nrho cov txheej txheem. Cov xov yog lub teeb yuag thiab siv qhov tsawg kawg nkaus ntawm cov peev txheej piv nrog cov txheej txheem.

Dab tsi yog Multitasking?

Lub khoos phis tawj tuaj yeem ua haujlwm sib txawv tib lub sijhawm. Piv txwv li, browser, Word application, PowerPoint daim ntawv thov, lub tshuab xam zauv txhua tus tuaj yeem khiav tib lub sijhawm. Yog li, lub khoos phis tawj tau ua ntau yam haujlwm lossis ntau yam txheej txheem tib lub sijhawm. Nws yog hu ua Multitasking. Txawm hais tias lub khoos phis tawj tuaj yeem ua tau ntau yam haujlwm tib lub sijhawm, nws muaj cov haujlwm tshwj xeeb uas tuaj yeem ua tiav ib zaug.

Khiav ntau cov txheej txheem yuav txo qis kev suav nrawm vim nws xav tau kev pab ntxiv. Multitasking ua kom cov khoom tsim tau ntau dua vim tias ntau qhov kev pabcuam tau ua haujlwm ib txhij. Nws kuj yog ib qho yooj yim rau cov neeg siv kom pom qhov hloov tshiab tam sim.

Dab tsi yog qhov zoo sib xws ntawm Multithreading thiab Multitasking?

Ob txoj hauv kev tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub cev

Qhov txawv ntawm Multithreading thiab Multitasking yog dab tsi?

Multithreading vs Multitasking

Multithreading yog los ua ntau cov xov hauv ib txheej txheem ib txhij. Multitasking yog khiav ntau cov txheej txheem ntawm lub computer ib txhij.
Kev ua tiav
Nyob hauv Multithreading, CPU hloov ntawm ntau cov xov hauv tib txoj kev. Nyob rau hauv Multitasking, CPU hloov ntawm ntau cov txheej txheem los ua kom tiav qhov kev ua tiav.
Kev sib qhia
Nyob rau hauv Multithreading, cov peev txheej tau muab faib rau ntau cov xov hauv ib txheej txheem. Nyob hauv Multitasking, cov peev txheej tau muab faib ua ntau yam txheej txheem.
Kev nyuaj siab
Multithreading yog lub teeb-yim thiab yooj yim los tsim. Multitasking yog qhov hnyav hnyav thiab tsim kom nyuaj dua.

Summary – Multithreading vs Multitasking

Multithreading thiab Multiprocessing ua cov xov thiab cov txheej txheem tib lub sijhawm. Qhov txawv ntawm Multithreading thiab Multitasking yog hais tias nyob rau hauv multithreading, ntau threads nyob rau hauv ib tug txheej txheem yog executing concurrently thiab nyob rau hauv multitasking, ntau txheej txheem yog khiav concurrently. Txawm hais tias cov ntsiab lus zoo sib xws, lawv yog cov ntsiab lus sib txawv. Txawm li cas los xij, ob qho no yog cov ntsiab lus tseem ceeb hauv Computer Science.
