Hauv Kwv Tij Chaw nyob Hom, Qhov Program Counter (PC) yog tus sau npe implicitly. Yog li, cov chaw nyob zoo yog tsim los ntawm kev ntxiv cov lus qhia tom ntej chaw nyob mus rau chaw nyob teb. Vim li no, Qhov Chaw Nyob Zoo = 302 + 400 = 702.
Ntxiv rau qhov no, koj yuav suav li cas qhov chaw nyob thiab chaw nyob ntawm lub cev?
Txhawm rau xam qhov chaw nyob ntawm lub cev:
- saib tus lej nplooj ntawv hauv nplooj ntawv thiab tau txais tus lej ncej.
- los tsim qhov chaw nyob, ncej = 17 khoom; offset = 12 ntsis; ces 512 = 29. 1m = 220 => 0 - (229-1) yog lub ntsiab nco yog 512 k, ces qhov chaw nyob yog 29 khoom.
xam qhov chaw nyob ntawm lub cev li cas? Yog li ntawd, Chaw nyob ntawm lub cev = Base Chaw nyob + Offset. Piv txwv li cov ntaub ntawv ntu tuav lub Base Aaddress li 1000h thiab cov ntaub ntawv koj xav tau tam sim no nyob rau hauv 0020h qhov chaw nco (Offset) ntawm Cov Ntaub Ntawv Ntu. Cov xam ntawm qhov tseeb chaw nyob yog ua raws li nram no. Yog li qhov tseeb chaw nyob yog 10020h.
Kuj nug, qhov chaw nyob zoo ntawm lub hauv paus sau npe suav li cas?
Base register chaw nyob hom: Base register chaw nyob hom yog siv los siv inter segment hloov chaw tswj. Nyob hauv hom no chaw nyob zoo yog tau los ntawm kev ntxiv base register nqi rau chaw nyob teb tus nqi. UA = Base sau npe + Chaw nyob teb tus nqi. PC = Base sau npe + Tus nqi txheeb ze.
Qhov chaw nyob zoo hauv microprocessor yog dab tsi?
Chaw Nyob zoo los yog Offset Chaw nyob : Qhov offset rau lub cim xeeb operand yog hu ua operand's chaw nyob zoo los yog EA. Nws yog tus lej 16 uas tsis tau muab teev tseg uas qhia txog qhov kev ua haujlwm qhov deb hauv bytes los ntawm qhov pib ntawm ntu uas nws nyob. Hauv 8086 peb muaj cov ntawv sau npe thiab cov ntawv sau npe.

Qhov chaw nyob IP twg raug muab ua qhov chaw nyob ntiag tug?
Tus IPv4 chaw nyob RFC1918 lub npe IP chaw nyob ntau Tus lej ntawm qhov chaw nyob 24-ntsis thaiv 10.0.0.0 - 10.255.255.255 16777216 20-ntsis thaiv 172.16.0.0 - 172.31.255.255 block 104.65.6 2018.25.65
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
Qhov chaw nyob ntawm lub cev thiab qhov chaw nyob qhov chaw nyob yog dab tsi?
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 fora program hu ua Logical Address Space
Koj tuaj yeem txheeb xyuas lub chaw tsim daim npav network li cas los ntawm nws qhov chaw nyob MAC?
Koj tuaj yeem txheeb xyuas lub chaw tsim daim npav network li cas los ntawm nws qhov chaw nyob MAC? koj txheeb xyuas lub network Card Chaw tsim khoom los ntawm saib thawj rau tus lej ntawm MAC chaw nyob
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
