Ntau hom kev sib txuas lus / internetworkingdevices
- Repeater: Kuj hu ua regenerator, nws yog hluav taws xob ntaus ntawv 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 tib yam hom .
- Routers: Lawv relay pob ntawv ntawm ntau qhov sib cuam tshuam tes hauj lwm (i.e. LANs of txawv hom ).
- Rooj vag:
Yog li ntawd, dab tsi yog qhov sib txawv ntawm cov khoom siv hauv internet siv hauv lub network?
Hom khoom siv network
- Hub.
- Hloov.
- Router.
- Choj.
- Rooj vag.
- Modem.
- Repeater.
- Access Point.
Ib yam li ntawd, plaub lub tshuab ua haujlwm hauv internet yog dab tsi? 4.2 INTERNETWORKING Devices Lub computer network tuaj yeem tsim los ntawm kev siv ntau lub network khoom siv xws li cables, Network InterfaceCards (NICs), Modems, Repeaters, Hubs, Choj, Hloov, thiab Gateways. Cov hauv qab no yog ntau yam cov khoom siv hauv internet uas yog siv los tsim LAN/WAN.
Tsis tas li ntawd, kev sib txuas lus thiab kev siv internet ua haujlwm yog dab tsi?
Ib siv internet ua haujlwm yog ib lo lus siv dav rau txhua yam khoom siv hauv tes hauj lwm uas txuas txawv network peev txheej. Ntsiab khoom siv uas suav nrog a network yog routers, txuas hniav, repeaters thiab rooj vag. Tag nrho khoom siv muaj cais nruab qhov nta, per network xav tau thiab scenarios.
Dab tsi yog hub thiab nws hom?
Muaj peb yam yooj yim hom ntawm hubs . Passive Hub : Qhov no hom ntawm tsis amplify lossis boostthe teeb liab. Nws tsis manipulate los yog saib cov tsheb uas crossesit. Lub passive hub tsis xav tau hluav taws xob ua haujlwm. Active Hub : Nws amplifies lub teeb liab tuaj ua ntej dhau nws mus rau lwm qhov chaw nres nkoj.

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
Dab tsi yog qhov sib txawv ntawm cov keyboards hauv kev sib txuas lus?
Hom Network Switches LAN Hloov lossis Active Hub. Kuj tseem hu ua localareanetwork lossis Ethernet hloov, cov cuab yeej no siv los txuas cov ntsiab lus ntawm lub tuam txhab sab hauv LAN. Unmanaged Network Switches. Managed Hloov. Routers
