Symmetric multiprocessing ( SMP ) yog ib qho kev siv computer uas muaj ob lossis ntau dua processors txuas rau asingle memory thiab operating system (OS). SMP sib txuas ntau cov txheej txheem los ua kom tiav cov txheej txheem nrog kev pab ntawm tus tswv OS, uas tswj hwm kev faib khoom, ua tiav thiab kev tswj hwm.
Ib yam li ntawd, nws tau nug, SMP thiab AMP yog dab tsi?
AMP sawv rau Asymmetric Multi-Processing; SMP txhais tau tias Symmetric Multi-Processing. Cov ntsiab lus no tsis yog pob tshab. Yog li, kuv yuav sim ua kom muaj kev ua haujlwm niaj hnub no.
Tom qab ntawd, lo lus nug yog, koj txhais li cas los ntawm multiprocessor system? Multiprocessor Kev khiav haujlwm Qhov system hais txog kev siv ob lossis ntau qhov chaw ua haujlwm hauv nruab nrab (CPU) hauv ib lub computer qhov system . Cov no ntau CPUs yog hauv kev sib txuas lus sib koom sib koom lub tsheb npav hauv computer, nco thiab lwm yam khoom siv peripheral. Cov no systems yog hu ua tightlycoupled tshuab.
Ib yam li ntawd, tib neeg nug, dab tsi yog txhais los ntawm multiprogramming?
Multiprogramming yog ib daim ntawv rudimentary ntawm parallel ua nyob rau hauv uas ob peb cov kev pab cuam yog khiav nyob rau tib lub sij hawm ntawm ib tug uniprocessor. Txij li thaum muaj tsuas yog ib tug processor, muaj peev xwm tsis muaj tseeb ib txhij ua tiav ntawm cov kev pab cuam sib txawv. Rau tus neeg siv nws zoo nkaus li tias txhua qhov kev zov me nyuam ua haujlwm tib lub sijhawm.
Dab tsi yog qhov txawv ntawm symmetrical thiab asymmetric multiprocessing?
Hauv Symmetric Multiprocessing , processors qhia tib lub cim xeeb. Qhov tseem ceeb Qhov sib txawv ntawm Symmetric thiab Asymmetric Multiprocessing yog in SymmetricMultiprocessing tag nrho cov processor hauv system runtasks hauv OS. Tab sis, hauv Asymmetric Multiprocessing tsuas yog tus tswv processor khiav haujlwm hauv OS.

Lub hom phiaj ntawm hom lus hom lus yog dab tsi?
Hom Lus Specification. Ib Hom Lus Qhia Tshwj Xeeb (CLS) yog ib daim ntawv uas hais tias yuav ua li cas cov khoos phis tawj tuaj yeem hloov mus rau hauv Cov Lus Qhia Nruab Nrab (CIL) code. Thaum ntau hom lus siv tib bytecode, qhov sib txawv ntawm qhov kev pab cuam tuaj yeem sau ua hom lus sib txawv
Dab tsi yog super hom thiab sub hom?
Lub supertype yog ib hom kev sib koom ua ke uas muaj kev sib raug zoo nrog ib lossis ntau hom subtypes. Ib tug subtype yog ib pawg sub-pab pawg ntawm cov koom haum hauv ib lub koom haum uas muaj txiaj ntsig rau lub koom haum thiab uas qhia cov yam ntxwv sib xws lossis kev sib raug zoo sib txawv ntawm lwm pab pawg
Dab tsi yog qhov txawv ntawm Hom C thiab Hom F ntsaws?
Hom F zoo ib yam li C tshwj tsis yog tias nws nyob ib puag ncig thiab muaj qhov sib ntxiv ntawm ob qhov txuas hauv av ntawm sab ntawm lub ntsaws. Hom C plug haum zoo kawg nkaus rau hauv lub qhov (socket) typeF. Lub qhov (socket) yog recessed los ntawm 15 hli, yog li ib feem ntawm cov ntsaws ntsaws tsis tuaj yeem ua rau poob siab
Social engineering yog dab tsi thiab nws lub hom phiaj yog dab tsi?
Social engineering yog lo lus siv rau ntau yam kev ua phem ua phem uas ua tiav los ntawm tib neeg kev sib cuam tshuam. Nws siv kev puas siab puas ntsws los ntxias cov neeg siv kom ua yuam kev kev ruaj ntseg lossis muab cov ntaub ntawv rhiab
Dab tsi yog tus hais lus sau nws lub hom phiaj thiab dab tsi yog yam tseem ceeb uas yuav tsum nco ntsoov txog cov lus hais?
Cov neeg hais lus sau ntawv yog cov ntawv qhia uas tus neeg nthuav qhia siv thaum nthuav qhia qhov kev nthuav qhia. Lawv pab tus neeg nthuav qhia nco txog cov ntsiab lus tseem ceeb thaum muab kev nthuav qhia. Lawv tshwm sim ntawm tus swb thiab tuaj yeem pom tsuas yog los ntawm tus tshaj tawm thiab tsis yog cov neeg tuaj saib
