Tej Yam Koj Yuav Tsum Paub Txog Tsev Network
Lub network tau los ua ib qho tseem ceeb ntawm peb lub neej niaj hnub. Yog tias koj muaj lub computer hauv tsev, kuv paub tseeb tias koj tsis paub nrog lub tsev network. Hauv yav dhau los, tsuas muaj ib txoj kev rau kev sib koom tes hauv tsev network-wired network. Txawm li cas los xij, qhov pace ntawm kev siv technology network yeej tsis qeeb qeeb, thiab tam sim no, muaj wireless network, uas ua rau nws yooj yim dua tau txais kev nkag mus rau lub network. Raws li peb nyob hauv wired network lossis wireless network ib puag ncig txhua hnub, nws yog qhov tsim nyog rau peb paub txog lub network, tshwj xeeb yog hauv tsev network. Tsab xov xwm no yuav qhia txog qee txoj kev paub txog wired network thiab wireless network.
Hauv wired network, muaj ob qho tseem ceeb tshaj plaws, ib qho yog router thiab ib qho yog network txuas.
Peb paub hais tias tus router yog tsim los nrog ob peb lub chaw nres nkoj ntawm sab xub ntiag los yog sab nraud ntawm lub tsev, xws li ib lub WAN network (chaw sib kis network), plaub LAN (zos cheeb tsam network) thiab ib qhov chaw nres nkoj nkag. Kuj, muaj qee qhov LED teeb rau tso saib ntaus xwm txheej. Tag nrho WAN chaw nres nkoj thiab LAN ports yog RJ45 interface, yog li ib kawg ntawm cov kab txuas network tau muab txuas rau lawv. Tab sis rau lwm qhov kawg ntawm network cable, muaj ib qho txawv ntawm WAN chaw nres nkoj thiab LAN chaw nres nkoj. Rau qhov chaw nres nkoj WAN, lwm qhov kawg ntawm lub network cable txuas rau hauv Internet qhov chaw, xws li cov chaw pabcuam broadband; thaum lub sij hawm rau qhov chaw nres nkoj ntawm LAN, lwm qhov kawg ntawm lub network cable txuas rau hauv lub RJ45 chaw nres nkoj ntawm Ethernet-npaj txawb, zoo li lub computer. Lub sij hawm koj ntsaws lub cuab yeej rau hauv lub router, koj muaj koj tus kheej lub wired network.
Raws li kev xaiv ntawm network cable siv rau kev txuas, xws li cat5e cable lossis cat6 cable yuav tsum tau. Qhov tseeb network cabling tus qauv tam sim no siv yog cat6 cable, uas yog tsim los ua kom ceev thiab ntau txhim khu kev qha cat5e cable. Ob ntawm lawv txhawb cov ntaub ntawv ceev ntawm 10Mb / s, 100Mb / s thiab 1000Mb / s, thaum cat6 cable tau mus cuag 10Gb / s. Kuj, cat5e cable thiab cat6 cable yuav siv tau los ntawm kev sib hloov, Rau feem ntau hauv tsev pab, dab cat5 cable tau los pab yog ntau tshaj li txaus. Tab sis yog tias koj xav txog cov ntawv pov thawj yav tom ntej, cat6 cable yog ib qho kev xaiv zoo rau ntxiv rau nws cov nqi siab.
Rau wireless network, li tsis siv network txuas mus rau lub router. Xwb, lawv siv xov tooj cua sib txuas lus hu ua Wi-Fi (Wireless Fidelity). Qhov no yog qhov sib txawv ntawm qhov sib txawv ntawm qhov wireless network thiab wired network. Cov siv siv nyob rau hauv wireless network tsis tas yuav muaj ports, tsuas yog antennas, uas yog qee zaum muab zais hauv cov cuab yeej nws tus kheej. Yuav kom tsim ib qho chaw rau Wi-nkaus, yuav tsum muaj qhov point point (AP).
Ib qho chaw nkag tau yog ib qho tseem ceeb ntawm lub xov tooj cua uas yog txoj kev qhia Wi-nkaus rau Wi-nkaus cov neeg siv xa mus. Feem ntau, txhua lub wireless network belongs rau ib qho chaw nkag. Piv txwv, thaum koj dai ib ncig ntawm qee lub khw muag khoom, koj tuaj yeem pom ntau lub tes hauj lwm ntxiv rau ntawm koj lub xov tooj qhov screen thiab txhua tus ntawm lawv yog ib qho chaw nkag. Kev xa mus rau hauv tsev wireless network, koj tuaj yeem yuav ib qho chaw nkag mus rau nyias thiab txuas mus rau lub router. Tam sim no nyob rau hauv lub lag luam, ib hom wireless router yog muaj, uas yog ib txwm router nrog ib tus taw tes built-in. Qhov no ua rau koj lub wireless network tsev yooj yim dua.
Hauv ib lub tsev nyob hauv tsev, feem ntau yog ob qho tib si wired thiab wireless, thiab tag nrho lawv sib tham. Tsim kom muaj kev ruaj khov hauv tsev, nws yog ib qho tseem ceeb uas yuav tau xaiv cov kev taw qhia kom zoo, network txuas thiab qhov chaw nkag. Txawm hais tias FOCC tsis muab cov router, lawv muaj kev sib txuas zoo network thiab kev nkag mus rau qhov wireless.
