Nyob hauv lub ntiaj teb ntawm cov khoos phis tawj, kev sib txuas lus yog kev xyaum ntawm kev sib txuas ob lossis ntau lub khoos phis tawj ua ke rau lub hom phiaj ntawm kev sib qhia cov ntaub ntawv. Cov tes hauj lwm yog tsim los ntawm kev sib txuas ntawm lub khoos phis tawj kho vajtse thiab khoos phis tawj software. Qee qhov kev piav qhia ntawm kev sib tham pom nyob rau hauv cov phau ntawv thiab cov lus qhia yog cov kev txawj ntse, tsim los rau cov tub ntxhais kawm thiab cov kws tshaj lij, thaum lwm tus tau npaj ntau dua rau hauv tsev thiab kev lag luam siv computer network. Nov yog qhov ceev, yooj yim saib ntawm cov ntsiab lus tseem ceeb ntawm kev sib tham.
Type of Computer Networks
Networks tuaj yeem faib ua ntau txoj hauv kev. Ib txoj hauv kev txhais cov hom network raws li thaj chaw uas nws nthuav. Xwb, cov tes hauj lwm kuj tuaj yeem raug cais raws li topology lossis ntawm hom kev cai uas lawv txhawb.
Hom khoom siv Network: Lub Kho vajtse
Lub tsev thaiv ntawm lub tsev computer network suav nrog adapters, routers, thiab / lossis cov ntsiab lus nkag. Wired (thiab hybrid wired / wireless) kev sib txuas kuj tseem cuam tshuam nrog cables ntawm ntau hom. Thaum kawg, cov tuam txhab lag luam loj loj, tshwj xeeb, feem ntau ntiav lwm cov cuab yeej siv siab heev rau kev sib txuas lus tshwj xeeb.
Ethernet
Ethernet yog lub cev thiab cov ntaub ntawv txuas txheej txheej txheej txheem rau cov chaw hauv cheeb tsam. Cov tsev, tsev kawm ntawv, thiab chaw ua haujlwm thoob ntiaj teb feem ntau siv Ethernet-tus qauv cables thiab adapters rau network tus kheej lub computer.
Wireless Local Area Networking (WLAN)
Wi-Fi yog qhov nrov tshaj plaws kev sib txuas lus wireless raws tu qauv rau cov chaw hauv cheeb tsam. Cov tsev ntiag tug thiab kev lag luam network thiab pej xeem hotspots siv Wi-Fi los txuas cov khoos phis tawj thiab lwm yam khoom siv wireless rau ib leeg thiab Is Taws Nem. Bluetooth yog lwm txoj kev cai wireless uas feem ntau siv hauv cov xov tooj ntawm tes thiab lub khoos phis tawj rau kev sib txuas lus luv luv.
Internet Service
Cov thev naus laus zis siv los txuas rau hauv is taws nem txawv dua li cov siv los txuas cov khoom siv hauv cheeb tsam hauv zos. Cov neeg siv cov kab (DSL), cable modems, thiab fiber ntau muab cov kev pabcuam hauv internet ruaj khov, thaum WiMax thiab LTE kuj txhawb kev sib txuas ntawm tes. Hauv thaj chaw thaj chaw uas cov kev xaiv siab ceev no tsis muaj, cov neeg siv khoom raug yuam kom siv cov kev pabcuam qub qub, satellite, lossis tseem hu xovtooj hauv internet xwb.
TCP/IP thiab lwm yam kev cai hauv Internet
TCP/IP yog thawj lub network raws tu qauv ntawm internet. Lub ntsiab lus yog hais txog Kev Sib Txuas Lus Tswjhwm thiab Internet raws tu qauv, ob lub ntsiab lus uas tus qauv ua raws. Ib tsev neeg muaj feem cuam tshuam ntawm cov txheej txheem tsim nyob rau sab saum toj ntawm TCP / IP tso cai rau web browsers, email, thiab ntau lwm daim ntawv thov sib txuas lus thoob plaws ntiaj teb. Cov ntawv thov thiab cov khoos phis tawj siv TCP / IP txheeb xyuas ib leeg nrog qhov chaw nyob IP, uas yog cov lej uas feem ntau zoo li … (ie, 192.168.0.51).
Network Routing, Switching, thiab Bridging
Feem ntau lub khoos phis tawj sib txuas lus ncaj qha los ntawm qhov chaw mus rau qhov chaw siv khoom siv siv ib qho ntawm peb txoj kev: routing, switching, thiab bridging. Routers siv qee cov ntaub ntawv chaw nyob hauv network uas muaj nyob hauv cov lus xa lawv ua ntej mus rau lawv qhov chaw nyob (feem ntau ntawm lwm lub routers). Cov keyboards siv ntau yam thev naus laus zis zoo ib yam li routers tab sis feem ntau txhawb nqa hauv cheeb tsam network nkaus xwb. Kev sib txuas tso cai rau cov lus ntws ntawm ob hom kev sib txuas ntawm lub cev.
