Tshua

Cia peb siv qee lub sijhawm tham txog network.

Txhua tus neeg feem coob paub txog lub network hauv tsev yog tias koj xav tau ib qho, thiab koj xav kom nws ua haujlwm. Ntawm Gleeson's Home Entertainment thiab Automation, peb ib txwm siv zog los qhia peb cov neeg siv khoom, thiab lub hli dhau los peb tau tham txog qhov tseem ceeb ntawm lub tsev network tuaj yeem ua tau. Lub hlis no, peb yuav los saib qee qhov kev daws teeb meem hauv tsev nrov thiab sib tham txog cov txiaj ntsig ntawm txhua tus. Thaum kawg, koj yuav tsis tsuas paub me ntsis ntxiv txog kev sib txuas lus, tab sis koj yuav muaj peev xwm txiav txim siab seb qhov twg yog qhov zoo rau koj lub tsev.

Tsev thiab kev sib koom tes

Peb yuav piav qhia luv luv txog qhov sib txawv network yog dab tsi, lawv yog dab tsi rau thiab nyob rau hauv dab tsi lawv siv.

nrog cov kab mob

Thaum nws los txog hauv tsev tes hauj lwm, muaj ob yam tseem ceeb: Wired thiab wireless. Qhov no yog hais txog cov khoom siv uas nkag tau rau hauv Internet txuas rau koj LAN. Nyob rau hauv cov ntaub ntawv ntawm ib tug wired network, nws feem ntau tuaj rau koj lub tsev los ntawm lub cable kab thiab ces txuas mus rau ib tug modem thiab / los yog router. Los ntawm qhov ntawd, cov khoom siv thoob plaws hauv tsev txuas ntawm Ethernet cable mus rau modem ntawm Ethernet hloov.

Hom kev sib txuas no feem ntau tshwm sim hauv kev tsim kho tshiab, qhov uas nws yooj yim los khiav lub cable thoob plaws hauv tsev. Qhov zoo ntawm kev sib txuas hauv tsev yog qhov pom tseeb: wired tes hauj lwm yeej ib txwm yuav nrawm dua thiab txhim khu kev ntseeg ntau dua li cov tes hauj lwm wireless. Wired networks muaj ntau bandwidth thiab tsis cuam tshuam los ntawm ntau yam thiab cuam tshuam xws li wireless. Qhov tsuas yog lub fwj dej tiag tiag yog koj lub router hom / ceev thiab internet ceev uas koj them rau.

Tau kawg, wired tes hauj lwm kuj muaj lawv cov kev txwv, uas yog vim li cas wireless networks (Wi-Fi) thiaj li nrov.

Wireless

Nrog lub wireless network, koj tuaj yeem nkag mus rau Is Taws Nem yam tsis tau txuas nrog cable. Ib qho piv txwv zoo tshaj ntawm qhov no yog siv koj lub ntsiav tshuaj lossis lub xov tooj ntawm tes thaum taug kev ncig koj lub tsev. Thiab thaum hardwiring yog qhov zoo dua rau cov khoom siv zoo li qub xws li koj cov khoom khib nyiab lossis TV, tom qab lub tsev tsim, tej zaum yuav muaj qhov chaw uas nws tsis tuaj yeem khiav cov xov hlau tshiab. Qhov no yog qhov uas cov cuab yeej siv wireless ci ntsa iab: lub peev xwm nthuav dav dav hauv Is Taws Nem thoob plaws hauv tsev thiab sab nraum zoov nrog cov xaim tshiab me me thiab tsis muaj cov khoom siv txuas nrog.

Cov teeb meem tseem ceeb ntawm cov tes hauj lwm wireless yog ceev thiab kev ntseeg tau. Cov teeb liab Wi-Fi tuaj yeem cuam tshuam los ntawm lwm yam khoom siv hluav taws xob - txawm tias koj lub tub yees - thiab yog tias koj nyob ze koj cov neeg nyob ze, koj lub network Wi-Fi tuaj yeem sib tshooj nrog lawv thiab ua rau txhua tus neeg qeeb. Nyob ntawm seb koj lub tsev loj npaum li cas, koj yuav xav tau ntau lub ntsiab lus nkag mus kom ntseeg tau tias muaj kev pab cuam thoob plaws hauv koj lub tsev. Txoj cai dav dav ntawm tus ntiv tes xoo yog kom muaj ib qho chaw nkag wireless rau txhua 1.500 square feet, thiab koj kuj yuav tsum nco ntsoov suav nrog lub tiaj nraum qaum tsev yog tias koj xav nkag mus rau sab nraum zoov. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias feem ntau cov ntsiab lus nkag wireless (WAPS) xav tau lub zog thiab tej zaum yuav xav tau kev sib txuas ethernet rau lub ntsiab router, uas txhais tau hais tias kev sib txuas wireless tsis yog wireless tiag.

Cov Lus Qhia Ntxiv: Yog tias koj tau pom cov lej txawv txawv thiab cov ntawv zoo li 802.11ac, nws yuav tsum ua nrog tus qauv wireless koj lub router siv. 802.11ac yog nrawm dua li 802.11n qub, yog li khaws cia hauv siab thiab.

Thaum xub thawj, kev sib tham hauv tsev yuav zoo li nyuaj heev, tab sis nws tsis yog qhov nyuaj thaum koj nkag siab lub ntsiab lus siab. Tsis tas li, koj tsis yog tib tus uas yuav tsum daws koj lub network hauv tsev.

LAN, WLAN, MAN, WAN, PAN: paub hom kev sib txuas tseem ceeb

Hauv cov ntsiab lus ntawm cov ntaub ntawv thev naus laus zis, lub network yog tsim los ntawm ntau lub processors uas sib cuam tshuam thiab sib qhia cov peev txheej rau ib leeg. Ua ntej, cov tes hauj lwm no muaj nyob rau hauv cov chaw ua haujlwm (hauv cheeb tsam network), tab sis dhau sij hawm qhov xav tau los sib pauv cov ntaub ntawv ntawm cov txheej txheem ua haujlwm tau nce, uas tau nce mus rau lwm hom kev tes hauj lwm. Nkag siab tias qee yam ntawm cov khoos phis tawj tseem ceeb txhais li cas.

LAN – Local Area Network

Cov cheeb tsam hauv cheeb tsam sib cuam tshuam cov khoos phis tawj hauv tib qhov chaw lub cev. Qhov no tuaj yeem tshwm sim hauv ib lub tuam txhab, tsev kawm lossis koj lub tsev, tso cai rau kev sib qhia cov ntaub ntawv thiab cov peev txheej ntawm cov khoom siv uas koom nrog.

MAN – Metropolitan Network

Cia peb xav txog, piv txwv li, tias ib lub tuam txhab muaj ob lub chaw ua haujlwm hauv tib lub nroog thiab xav kom cov khoos phis tawj txuas nrog. Rau qhov no yog Lub Nroog Thaj Chaw Network, lossis Metropolitan Network, uas txuas ntau lub Zos Hauv Cheeb Tsam hauv ib lub vojvoog ntawm ob peb kaum mais.

WAN – Wide Area Network

Wide Area Network mus ntxiv me ntsis tshaj tus txiv neej thiab tuaj yeem npog thaj tsam loj dua, xws li lub teb chaws lossis txawm tias yog ib lub teb chaws.

WLAN – Wireless Local Area Network

Rau cov neeg uas xav ua yam tsis muaj cables, WLAN, lossis wireless hauv cheeb tsam network, tej zaum yuav yog ib qho kev xaiv. Hom kev sib txuas no txuas rau Is Taws Nem thiab tau siv dav hauv ob qho tib si hauv tsev thiab chaw lag luam, nrog rau hauv cov chaw pej xeem.

WMAN - Wireless Metropolitan Network

Nws yog lub wireless version ntawm MAN, nrog ntau yam ntawm kaum kilometers, thiab tso cai rau kev sib txuas ntawm chaw ua hauj lwm tes hauj lwm ntawm tib lub tuam txhab los yog tsev kawm ntawv cov tsev kawm ntawv.

WWAN - Wireless Wide Area Network

Nrog rau kev ncav cuag ntau dua, WWAN, lossis wireless network dav dav, mus txog ntau qhov chaw hauv ntiaj teb. Yog li ntawd, WWAN yog qhov yooj yim dua rau lub suab nrov.

SAN – Cia Chaw Network

SANs, lossis Storage Area Networks, yog siv rau kev sib txuas lus ntawm ib lub server thiab lwm lub khoos phis tawj, thiab tsuas yog txwv rau qhov ntawd.

PAN – Personal Area Network

PAN-hom tes hauj lwm, lossis kev sib txuas ntawm tus kheej hauv cheeb tsam, yog siv rau cov khoom siv los sib txuas lus nyob ib puag ncig ncaj ncees. Ib qho piv txwv ntawm qhov no yog Bluetooth thiab UWB tes hauj lwm.
