2024 Tus sau: Lynn Donovan | [email protected]. Kawg hloov kho: 2023-12-15 23:47
Local Area Network
Hauv qhov no, hom network twg feem ntau pom nyob hauv tsev?
Ethernet
Tsis tas li ntawd, 4 hom network yog dab tsi? Lub computer network feem ntau yog ntawm plaub hom:
- LAN (Local Area Network)
- PAN (Tus Kheej Network Network)
- MAN (Metropolitan Area Network)
- WAN (Wide Area Network)
Hais txog qhov no, dab tsi yog 5 hom kev sib txuas hauv computer feem ntau?
Muaj ntau hom computer networks , cov hom hom ntawm cheeb tsam tes hauj lwm suav nrog cov tsib : LAN - Local Area Network , WAN - Dav dav Network , WLAN - Wireless Local Area Network , MAN - Cheeb Tsam Thaj Chaw Network thiab CAN - Campus Area Network.
2 hom LAN networks yog dab tsi?
Hom Computer Network: LAN, MAN thiab WAN
- Local Area Network (LAN) Hauv cheeb tsam network yog ib pawg ntawm cov khoos phis tawj txuas nrog ib leeg hauv ib qho chaw me me xws li tsev kawm ntawv, tsev kho mob, chav tsev thiab lwm yam.
- Metropolitan Area Network (MAN) MAN network npog thaj tsam loj dua los ntawm kev sib txuas LANs mus rau lub network loj ntawm cov khoos phis tawj.
- Wide area network (WAN)

Dab tsi yog hom sib txawv ntawm kev sib txuas hauv internet ua haujlwm li cas?
Kev sib txawv ntawm kev sib txuas / internetworkingdevices Repeater: Kuj hu ua regenerator, nws yog ib qho khoom siv hluav taws xob uas ua haujlwm tsuas yog ntawm lub cev txheej. Txuas hniav: Cov no ua haujlwm ob qho tib si hauv lub cev thiab cov ntaub ntawv txuas ntawm LANs ntawm tib hom. Routers: Lawv relay pob ntawv ntawm ntau qhov sib txuas sib txuas (piv txwv li LANs ntawm ntau hom). Rooj vag:
Dab tsi yog tag nrho cov kab kev sib txuas lus uas xav tau rau kev sib txuas tag nrho rau taw tes network ntawm tsib lub khoos phis tawj rau lub khoos phis tawj?
Tus naj npawb ntawm cov kab sib txuas lus uas yuav tsum tau muaj rau kev sib txuas tag nrho ntawm qhov taw tes rau-taw tes ntawm yim lub khoos phis tawj yog nees nkaum yim. Ib tug tag nrho txuas cuaj lub computer network yuav tsum tau peb caug rau kab. Ib tug tag nrho txuas kaum lub computer network yuav tsum tau plaub caug tsib kab
Dab tsi yog qhov sib txawv ntawm kev sib txuas lus taw qhia thiab kev sib txuas tsis raug cai?
Qhov txawv: Kev sib txuas lus taw qhia thiab kev sib txuas tsis muaj kev sib txuas Kev sib txuas lus taw qhia kev sib txuas ua rau muaj kev sib txuas thiab xyuas seb cov lus puas tau txais lossis tsis tau thiab xa rov qab yog tias muaj qhov yuam kev tshwm sim, thaum qhov kev pabcuam tsis sib txuas tsis tau lees tias xa xov
Dab tsi yog qhov txawv ntawm kev sib raug zoo unary kev sib raug zoo binary thiab kev sib raug zoo ternary?
Kev sib raug zoo tsis sib xws yog thaum ob tus neeg koom hauv kev sib raug zoo yog tib lub koom haum. Piv txwv li: Cov ncauj lus yuav yog qhov yuav tsum tau ua ua ntej rau lwm yam kev kawm. Kev sib raug zoo ternary yog thaum peb lub koom haum koom nrog kev sib raug zoo
Dab tsi yog qhov sib txawv tseem ceeb ntawm kev sib txuas lus tsis sib xws thiab kev sib txuas lus taw qhia?
1. Hauv kev sib txuas lus tsis muaj kev sib txuas lus tsis tas yuav tsim kev sib txuas ntawm qhov chaw (sender) thiab qhov chaw (receiver). Tab sis nyob rau hauv kev sib txuas-taw qhia kev sib txuas lus kev sib txuas lus yuav tsum tau tsim ua ntej hloov cov ntaub ntawv
