Peb cov khoom siv twg yog cov khoom siv nruab nrab hauv lub network? (Xaiv peb.)
- router .
- server.
- hloov.
- chaw ua haujlwm.
- network tshuab luam ntawv.
- wireless access point. Kev piav qhia: Cov khoom siv nruab nrab hauv a network muab network kev sib txuas mus rau qhov kawg khoom siv thiab xa cov neeg siv cov ntaub ntawv pob khoom thaum lub sijhawm sib txuas lus cov ntaub ntawv.
Kuj paub, dab tsi yog cov khoom siv nruab nrab hauv Packet Tracer?
Cov khoom siv nruab nrab (1.3.1.3) Cov khoom siv muab kev sib txuas thiab ua haujlwm tom qab ntawm qhov xwm txheej kom ntseeg tau tias cov ntaub ntawv ntws thoob plaws lub network. Cov khoom siv nruab nrab txuas tus tswv tsev rau lub network thiab tuaj yeem txuas ntau lub network rau ib tus neeg los tsim ib lub network.
Tsis tas li ntawd, qhov kev pabcuam twg yuav daws cov npe sau npe rau tus IP chaw nyob? Hauv TCP / IP raws tu qauv, txoj kev uas feem ntau siv rau daws server npe rau network chaw nyob tus Lub Npe System ( DNS ), ib tug Internetdirectory kev pabcuam tsim ob qho tib si los tso cai rau cov thawj coj hauv cheeb tsam los tsim thiab tswj cov ntaub ntawv uas daws server npe rau IP chaw nyob thiab ua kom cov ntaub ntawv no muaj
Ib yam li ntawd, cov cuab yeej siv wireless twg siv ntawm cov xov tooj ntse kom xa cov ntaub ntawv mus rau lwm lub cuab yeej nyob ze ze ze?
NFC lub Nyob ze Field Communication yog a ntse txoj kev sib koom cov ntaub ntawv nruab nrab ntawm ob smartphones . Nws a luv luv wireless kev sib txuas lus tshuab uas tso cai rau hluav taws xob khoom siv sib txuas lus nrog txhua tus lwm yam.
Dab tsi yog tus yam ntxwv ntawm kev sib koom ua ke network?
nws xa cov ntaub ntawv, suab, thiab video dua tib yam network infrastructure. Lub tuam txhab tab tom xav seb puas yuav siv cov neeg siv khoom / server lossis cov phooj ywg-rau-peer network.
