Qhov txawv nruab nrab ntawm Logical thiab qhov chaw nyob yog tias Logical chaw nyob yog generated by CPU nyob rau hauv foundations ntawm ib tug program. Ntawm qhov tod tes, lub qhov chaw nyob yog ib qhov chaw uas muaj nyob rau hauv lub memoryunit. Cov txheej txheem tag nrho logical chaw nyob tsim los ntawm CPU fora program hu ua Logical Chaw Nyob Qhov chaw.
Hauv qhov no, qhov chaw nyob thiab qhov chaw nyob hauv lub cev yog dab tsi?
Logical thiab Lub cev chaw nyob hauv OperatingSystem . Logical Chaw Nyob yog tsim los ntawm CPU thaum aprogram tab tom khiav. Cov cuab yeej kho vajtse hu ua Memory-ManagementUnit yog siv rau kev kos duab chaw nyob logical rau nws sib xws qhov chaw nyob . Chaw nyob ntawm lub cev qhia a lub cev qhov chaw ntawm cov ntaub ntawv xav tau hauv amemory.
Qhov chaw nyob lub cev txhais li cas? A qhov chaw nyob yog ib tug binarynumber nyob rau hauv daim ntawv ntawm logical siab thiab qis xeev ntawm ib chaw nyob busthat sib raug rau ib lub xovtooj ntawm qhov chaw khaws cia (tseem hu ua lub cim xeeb tseem ceeb), lossis rau ib qho kev sau npe hauv lub cim xeeb-mappedI / O (input / output) ntaus ntawv.
Ib yam li ntawd, koj ua li cas thiaj nrhiav tau qhov chaw nyob ntawm qhov chaw nyob ntawm lub cev?
Txhawm rau xam qhov chaw nyob ntawm lub cev:
- saib tus lej ntawm nplooj ntawv hauv nplooj ntawv thiab tau txais tus lej.
- los tsim qhov chaw nyob, ncej = 17 khoom; offset = 12 ntsis; ces 512 = 29. 1m = 220 => 0 - (229-1) yog lub cim xeeb yog 512 k, ces qhov chaw nyob yog 29 khoom.
Qhov chaw nyob logical yog dab tsi?
Logical chaw nyob yog set logicaladdresses uas tsim los ntawm ib qho kev pab cuam. Lub cev chaw nyob yog chaw nyob uas pom los ntawm lub cim xeeb thiab siv nkag mus rau lub cim xeeb. Virtual chaw nyob yog mapped nrog lub cev chaw nyob los ntawm kev tswj hwm lub cim xeeb.

Qhov txawv ntawm qhov chaw nyob thiab qhov chaw nyob yog dab tsi?
Qee zaum, 'txoj kev chaw nyob' hais txog koj lub cev qhov chaw nyob ntawm qib zoo dua hauv nroog. Piv txwv li, '1313Mockingbird Lane', tsis muaj lub nroog lub npe txuas nrog. Tab sis yog, feem ntau nws tsuas yog ib daim ntawv rov qab kom paub qhov txawv ntawm qhov chaw xa ntawv (thaum chiv keeb) thiab tam sim no e-mail chaw nyob, chaw nyob hauv web, IPaddress, thiab lwm yam
Dab tsi yog qhov sib txawv ntawm lub thawv thiab lub thawv ntawv thiab lub thawv ntawv yog dab tsi?
Ib lub thawv thiab cov ntawv nplawm (qee zaum hu ua boxplot) yog ib daim duab uas nthuav tawm cov ntaub ntawv los ntawm tsib lub ntsiab lus. Nyob rau hauv ib lub thawv thiab whisker zajlus: qhov kawg ntawm lub thawv yog lub sab sauv thiab sab quartiles, yog li lub thawv spans lub interquartile ntau yam. qhov nruab nrab yog cim los ntawm ib txoj kab ntsug hauv lub thawv
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
Dab tsi yog qhov chaw nyob thiab lub cev nyob hauv OS?
Qhov sib txawv yooj yim ntawm Logical thiab lub cev chaw nyob yog qhov chaw nyob Logical yog tsim los ntawm CPU hauv kev xav ntawm ib qho kev pab cuam. Ntawm qhov tod tes, qhov chaw nyob ntawm lub cev yog qhov chaw nyob uas muaj nyob hauv lub cim xeeb. Cov txheej txheem ntawm txhua qhov chaw nyob uas tsim los ntawm CPU rau ib qho kev pab cuam hu ua Logical Address Space
Qhov txawv ntawm qhov chaw nyob sib txuas lus thiab qhov chaw nyob ruaj khov yog dab tsi?
Qhov chaw nyob xa ntawv yog chaw nyob sib txuas lus piv txwv li qhov koj nyob tam sim no. & chaw nyob Apermanent yog ntawm koj cov ntaub ntawv yog sau rau ntawm koj daim ntawv pov thawj hnub yug & daim npav pov npav. Qhov chaw nyob ruaj khov & kev sau ntawv yuav zoo ib yam lossis txawv ntawm cov ntaub ntawv siv tau
