Virtualization zoo ib yam li abstraction tab sis nws tsis ib txwm zais cov txheej txheem qis. … Abstraction yog ib qho ntawm cov yam ntxwv tseem ceeb ntawm huab xam uas tso cai rau abstraction ntawm lub cev siv los zais cov ntsiab lus ntawm cov neeg siv khoom. Qhov kev ua haujlwm no tau txhawb nqa los ntawm kev siv tshuab virtualization.
Dab tsi yog virtualization abstraction?
VIRTUALIZATION. ○ Virtualization yog thev naus laus zis uas tso cai rau tsim ib qho abstraction (ib qho virtual version) ntawm cov khoom siv hauv computer, xws li kho vajtse architecture, operating system, cia, network, thiab lwm yam. Nrog rau qhov no abstraction, piv txwv li, ib lub tshuab tuaj yeem ua tau zoo li ntau lub tshuab ua haujlwm ntawm nws tus kheej.
Kev paub daws teeb meem thiab virtualization tau txais txiaj ntsig zoo li cas rau huab xam?
Huab suav siv ib yam dab tsi hu ua virtual abstraction rau ua kom sai sai ntawm cov ntawv thov thiab cov ntaub ntawv kom txo tau tus nqi thiab qhov nyuaj ntawm kev muab cov txheej txheem hauv qab, uas kuj ua haujlwm yooj yim.
Puas yog multiprogramming ua tau yam tsis muaj kev cuam tshuam?
Yog tsis muaj kev cuam tshuam, nws yuav ua tsis tau rau kev siv ntau qhov programming lossis sijhawm sib koom. … Yog tsis muaj timer cuam tshuam, lub sij hawm hlais tsis tuaj yeem tsim los faib CPU ntawm cov haujlwm. Interrupt Synchronization. Kev cuam tshuam lawv tus kheej yuav tsum tau synchronized.
Yuav ua li cas ntau lub cim xeeb faib lossis pub dawb yuav ua yam tsis muaj PCB rov siv dua?
Ntau npaum li cas lub cim xeeb ua haujlwm (faib lossis pub dawb) yuav ua nrog PCB rov siv dua? Qhov siab tshaj plaws ntawm 600 PCBs yuav xav tau, txhua yam yuav raug tso tawm thaum kawg ntawm kev khiav. Tag nrho yog 2600= 1, 200 lub cim xeeb Txij li thaum 100 txheej txheem yuav sib koom ua ke thaum twg los tau, 100 PCBs yuav nyob hauv lub cim xeeb ntawm qhov nruab nrab.
