Nyob rau niaj hnub no lub hnub nyoog digital, Ethernet keyboards ua lub luag haujlwm tseem ceeb hauv kev tsim thiab tswj kev sib txuas tsis sib haum xeeb. Kev nkag siab txog lawv cov yam ntxwv thiab cov txiaj ntsig yog qhov tseem ceeb, tshwj xeeb tshaj yog rau cov tib neeg uas xav ua kom zoo dua kev ua haujlwm hauv network. Tsab ntawv xov xwm no yog npaj los muab cov lus qhia dav dav ntawm Ethernet keyboards thiab yuav ua li cas lawv tuaj yeem txhim kho kev ntseeg tau ntawm lub network. Ib qho Ethernet hloov yog ib lub cuab yeej uas txuas ntau yam khoom siv, xws li khoos phis tawj, servers, thiab tshuab luam ntawv, mus rau thaj chaw hauv cheeb tsam network (LAN) lossis thaj chaw dav dav (WAN). Nws ua raws li lub hauv paus hub uas ua rau muaj kev sib txuas lus ntawm cov cuab yeej no los ntawm kev xa cov ntaub ntawv mus rau qhov chaw tsim nyog.

Ib qho kev hloov pauv PoE ua raws li kev hloov pauv, thiab tau kawg kuj tuaj yeem siv los ua qhov hloov pauv tsis tu ncua. Txawm li cas los xij, thaum siv los ua kev hloov pauv dav dav, tus nqi ntawm PoE hloov tsis tau ua kom tiav, thiab cov haujlwm muaj zog ntawm PoE hloov pauv yog nkim. Yog li ntawd, muaj cov xwm txheej uas tsis tas yuav muab DC lub zog rau cov cuab yeej txuas nrog thiab tsuas yog xav tau xa cov ntaub ntawv. , Nws raug nquahu kom xaiv qhov hloov pauv tsis tu ncua, thiab yog tias koj xav tau tsis yog cov ntaub ntawv xa mus nkaus xwb tab sis kuj tseem siv hluav taws xob, nws yog qhov zoo dua los xaiv PoE hloov. Yog tias koj xav tig qhov hloov pauv zoo tib yam rau hauv PoE hloov, yog tias koj ncaj qha sib sau cov hloov pauv mus rau hauv PoE hloov, lub zog hluav taws xob thiab cov ntaub ntawv xa mus tsis tuaj yeem ua tiav tib lub sijhawm.

PoE hloov yog hom tshiab ntawm ntau qhov kev hloov pauv. Vim muaj ntau daim ntawv thov ntawm PoE keyboards, tib neeg muaj qee qhov kev nkag siab ntawm PoE keyboards. Txawm li cas los xij, ntau tus neeg xav tias PoE keyboards tuaj yeem tsim lub zog ntawm lawv tus kheej, uas tsis muaj tseeb. Lub hwj chim hloov PoE feem ntau yog hais txog PoE hloov pauv uas muab lub zog rau lwm yam khoom siv los ntawm lub network cable yam tsis tau poob cov ntaub ntawv xa mus. Yog li siv PoE hloov pauv li cas? PoE hloov yog qhov hloov pauv nrog PoE kev ua haujlwm uas tuaj yeem txuas nrog qhov hloov pauv tsis tu ncua.
