Ib tus ntawm yog ib qho khoom siv lub cev hauv lub network ntawm lwm yam cuab yeej uas tuaj yeem xa, tau txais, lossis xa cov ntaub ntawv. Ib lub computer tus kheej yog cov node ntau tshaj plaws. hu ua computer node or internet node.

Modem, keyboards, hubs, txuas hniav, servers, thiab cov tshuab luam ntawv kuj yog cov nodes, zoo li lwm yam khoom siv uas txuas dhau Wi-Fi lossis Ethernet. Piv txwv li, lub network txuas peb lub khoos phis tawj thiab ib lub tshuab luam ntawv, nrog rau ob lub wireless ntxiv, muaj rau tag nrho cov nodes.

Nodes hauv lub computer network yuav tsum muaj qee hom kev qhia, xws li IP chaw nyob lossis MAC chaw nyob, rau lwm cov khoom siv hauv network kom paub txog lawv. Ib lub node yam tsis muaj cov ntaub ntawv no, lossis ib qho uas offline, tsis ua haujlwm raws li cov node.

Network Node Ua li cas?

Network nodes yog cov khoom siv lub cev uas ua rau lub network. Lawv feem ntau suav nrog txhua yam khoom siv uas ob leeg tau txais thiab tom qab ntawd sib txuas lus cov ntaub ntawv. Tab sis lawv yuav tau txais thiab khaws cov ntaub ntawv, xa cov ntaub ntawv mus rau lwm qhov, lossis tsim thiab xa cov ntaub ntawv hloov pauv.

Piv txwv li, lub khoos phis tawj ntawm lub koos pij tawj yuav rov qab tau cov ntaub ntawv online lossis xa email, tab sis nws tseem tuaj yeem tshaj tawm cov yeeb yaj kiab thiab rub tawm lwm cov ntaub ntawv. Lub tshuab luam ntawv network tuaj yeem tau txais cov ntawv thov los ntawm lwm cov khoom siv hauv lub network, thaum lub tshuab luam ntawv tuaj yeem xa cov duab rov qab mus rau lub computer. Lub router txiav txim siab seb cov ntaub ntawv twg mus rau cov khoom siv twg uas thov cov ntaub ntawv rub tawm hauv lub kaw lus, tab sis nws tseem tuaj yeem xa cov lus thov tawm mus rau pej xeem hauv internet.

Lwm Hom Nodes

Nyob hauv fiber ntau cable TV network, cov nodes yog cov tsev lossis cov lag luam uas txuas rau tib lub fiber ntau optic receiver.

Ib qho piv txwv ntawm ib lub node yog ib qho khoom siv uas muab kev pabcuam ntse hauv lub xovtooj ntawm tes, zoo li lub chaw nres tsheb hauv paus (BSC) lossis Gateway GPRS Support Node (GGSN). Hauv lwm lo lus, lub xov tooj ntawm tes yog dab tsi muab cov software tswj qab cov khoom siv, zoo li cov qauv nrog cov kav hlau txais xov uas xa cov teeb liab mus rau tag nrho cov khoom siv hauv lub network.

Ib tus supernode yog ib qho ntawm cov neeg sib koom ua ke uas ua haujlwm tsis yog ntawm ib txwm muaj tab sis kuj yog tus neeg rau zaub mov npe thiab cov cuab yeej uas xa cov ntaub ntawv rau lwm tus neeg siv hauv P2P system. Vim li no, supernodes xav tau CPU thiab bandwidth ntau dua li cov nodes li niaj zaus.

Dab tsi yog qhov teeb meem End-Node?

Lo lus "qhov teeb meem ntawm qhov kawg" yog hais txog kev pheej hmoo kev nyab xeeb uas tuaj nrog cov neeg siv txuas lawv lub khoos phis tawj lossis lwm yam khoom siv rau lub network rhiab, xws li lub cev (xws li tom haujlwm) lossis dhau huab (los ntawm txhua qhov chaw), thaum nyob ntawm Tib lub sijhawm uas siv tib lub cuab yeej ua haujlwm tsis muaj kev nyab xeeb.

Qee yam piv txwv suav nrog tus neeg siv kawg uas siv lawv lub laptop ua haujlwm hauv tsev tab sis tom qab ntawd kuaj xyuas lawv email ntawm lub network tsis muaj kev nyab xeeb xws li tom khw kas fes lossis tus neeg siv uas txuas lawv lub computer lossis xov tooj rau lub tuam txhab Wi-Fi network.

Ib qho kev pheej hmoo tseem ceeb tshaj plaws rau lub tuam txhab lag luam yog cov khoom siv tsis zoo uas ib tus neeg siv hauv lub network ntawd. Qhov teeb meem yog qhov tseeb zoo nkauj: sib xyaw lub network uas tsis muaj kev ruaj ntseg thiab kev lag luam network uas yuav muaj cov ntaub ntawv rhiab.

Tus neeg siv kawg lub cuab yeej yuav raug malware-nrog rau tej yam xws li keyloggers lossis cov kev pabcuam hloov ntaub ntawv uas rho tawm cov ntaub ntawv rhiab lossis txav malware mus rau lub network ntiag tug thaum nws nkag mus.

VPNs thiab ob qhov kev lees paub tseeb tuaj yeem pab kho qhov teeb meem no. Yog li tuaj yeem tshwj xeeb bootable tus neeg siv software uas tuaj yeem siv cov kev pabcuam tshwj xeeb rau cov chaw taws teeb.

Txawm li cas los xij, lwm txoj hauv kev yog qhia cov neeg siv yuav ua li cas txhawm rau tiv thaiv lawv cov khoom kom raug. Cov khoos phis tawj tus kheej tuaj yeem siv qhov program tiv thaiv kab mob kom lawv cov ntaub ntawv tiv thaiv los ntawm malware, thiab cov xov tooj smartphones tuaj yeem siv cov app antimalware zoo sib xws los ntes cov kab mob thiab lwm yam kev hem thawj ua ntej lawv ua rau muaj kev phom sij.

Lwm Node Meanings

"Node" kuj piav qhia txog cov ntaub ntawv hauv computer hauv cov ntaub ntawv ntoo. Zoo li tsob ntoo tiag tiag uas cov ceg tuav lawv cov nplooj, cov folders hauv cov qauv ntaub ntawv muaj cov ntaub ntawv. Cov ntaub ntawv hu ua nplooj los yog nplooj nplooj.

Lo lus "node" kuj tshwm sim hauv node.js, uas yog JavaScript runtime ib puag ncig uas ua rau server-sab JavaScript code. Lub "js" tsis yog hais txog JS cov ntaub ntawv txuas ntxiv siv nrog JavaScript cov ntaub ntawv; nws tsuas yog lub npe ntawm lub cuab yeej xwb.
