Cia peb qhia ua ntej yog dab tsi a CPU thiab yog dab tsi a tub ntxhais , ib qho chaw ua haujlwm hauv nruab nrab CPU , tuaj yeem muaj ntau yam tub ntxhais units, cov cores yog a processor los ntawm nws tus kheej, muaj peev xwm ua tiav ib qho kev pab cuam tab sis nws tus kheej muaj nyob rau hauv ib yam nti.
Tsis tas li ntawd, dab tsi yog txhais los ntawm cov tub ntxhais hauv processor?
A tub ntxhais yog ib feem ntawm a CPU uas tau txais kev qhia thiab ua kev suav, lossis ua, raws li cov lus qhia ntawd. Ib txheej ntawm cov lus qhia tuaj yeem tso cai rau software program ua haujlwm tshwj xeeb. Cov txheej txheem tuaj yeem muaj ib leeg tub ntxhais los yog ntau yam cores.
Tsis tas li ntawd, processor cores ua haujlwm li cas? Ib quad- core processor yog ib lub nti nrog plaub qhov kev ywj pheej hu ua cores uas nyeem thiab ua cov lus qhia hauv nruab nrab (CPU) xws li ntxiv, txav cov ntaub ntawv, thiab ceg. Nyob rau hauv lub chip, txhua tub ntxhais ua hauj lwm nrog rau lwm yam circuits xws li cache, kev tswj nco, thiab input/output (I/O) ports.
Dhau li ntawm no, CPU qhov (socket) thiab core yog dab tsi?
A lub qhov (socket) . yog lub cev lub qhov (socket) . qhov twg thephysical CPU capsules muab tso rau. Ib lub PC ib txwm tsuas muaj ib qho xwb lub qhov (socket) .. Cores yog tus naj npawb ntawm CPU - cores rau CPU tshuaj ntsiav. Tus qauv niaj hnub CPU rau tus qauv PC feem ntau muaj ob lossis plaub cores . Thiab ib co CPUs tuaj yeem khiav ntau dua ib qho xov sib luag rau ib CPU - tub ntxhais.
Dab tsi yog qhov txawv ntawm cov cores thiab cov txheej txheem cov txheej txheem?
Lub cev cores yog tus naj npawb ntawm lub cev cores , tiag hardware Cheebtsam. Logical cores yog tus naj npawb ntawm lub cev cores lub sij hawm tus naj npawb ntawm threads tuaj yeem khiav ntawm txhua tus tub ntxhais los ntawm kev siv hyperthreading. piv txwv li, kuv 4-core processor khiav ob threads ib core, yog li kuv muaj 8 logical processors.

Puas yog ip44 tib yam li ipx4?
Cov lej IP ib txwm muaj ntawm ob tus lej (lawv tuaj yeem muaj cov ntawv txuas ntxiv). e.g. IP44, IP66. e.g. IPX4, IP4X. Tus lej thib ob txhais tau hais tias kev tiv thaiv dej (drippingvertical, dripping slanted, spraying, splashing, jetting, immersion)
Puas yog software engineer thiab software tsim tawm tib yam?
Ib tug software engineer tau koom nrog software tsim kho; Tsis yog txhua tus tsim software, txawm li cas los xij, yog engineers. Kev txhim kho software thiab softwareengineering yog cov ntsiab lus sib cuam tshuam, tab sis lawv tsis txhais tau tib yam nkaus. Software engineering txhais tau hais tias siv cov qauv hauv engineering rau kev tsim software
Puas yog SQL Server thiab mssql tib yam?
SQL Server. SQL Server kuj hu ua MSSQL txhais tau tias Microsoft SQL Server. Nws tau tsim los ntawm Microsoft. SQL Server muaj qhov tshwj xeeb los koom ua ke nrog Visual studio rau cov ntaub ntawv programming
Puas yog Adobe pro tib yam li Adobe DC?
Hloov kho PDFs Txawm li cas los xij, Acrobat Pro DC tso cai rau koj hloov kho cov ntaub ntawv scanned thiab ntxiv cov ntawv hauv cov ntawv thawj font, thiab sib piv ob hom ntawm ib qho PDF. Acrobat Pro DC kuj tseem cia koj hloov PDFs rau cov ntaub ntawv Office, suav nrog Word, Excel, thiab PowerPoint
Puas yog tag nrho cov AC fais fab cables tib yam?
Cov lus teb luv luv: Tsis yog. Qhov no tsis yog hais tias tag nrho cov hlua hluav taws xob tau tsim sib npaug, tab sis kuv tsis tau pom ib lub hwj chim qaum uas nws tsis tuaj yeem tuav qhov raug 15A (US) max tam sim no ntawm lub qhov hluav taws xob
