LAN yog qhov nrov tshaj plaws uas peb siv niaj hnub no.LAN yog dab tsi?
Local Area Network (LAN) yog hais txog ib pawg ntawm cov khoos phis tawj sib txuas los ntawm ntau lub khoos phis tawj hauv ib cheeb tsam uas siv cov channel tshaj tawm.Qhov ntau muaj nyob rau hauv cheeb tsam no, cov khoom siv ntau dua tuaj yeem sib txuas lus.Thiab tsuas yog LAN ntawm lub kaw lus tuaj yeem sib txuas lus.Piv txwv li, cov khoom siv khoos phis tawj hauv LAN ntawm tib lub hloov pauv tuaj yeem sib cuam tshuam los ntawm MAC chaw nyob.
LAN muaj ntau yam ntxwv, ua rau nws yog ib qho tseem ceeb:
Feature 1: Qhov kev sib txuas ntawm LAN yog qhov tsawg heev, thiab nws tsuas yog txuas nrog hauv ib cheeb tsam uas muaj kev ywj pheej, xws li lub tsev lossis ib pawg hauv nruab nrab.Nws tuaj yeem nkag siab tias cov chav hauv tib lub tsev tuaj yeem txuas rau ib leeg los ntawm elevator.
Feature 2: Qhov nruab nrab kis tau tus mob (twisted khub, coaxial cable) tshwj xeeb nteg yog siv rau kev sib tham, thiab cov ntaub ntawv kis tau tus mob yog siab nyob rau hauv ntau ntawm 10Mb/s rau 10Gb/s.Piv txwv li, nyob rau hauv ib qho kev ywj pheej, seb puas yuav taug kev mus rau cov chav sib txawv lossis mus txog cov chav sib txawv ntawm lub elevator yog siv.Nws muaj feem xyuam rau kev kho vajtse tsim ntawm lub network interface siv.
Feature 3: Kev sib txuas lus luv luv, qis me ntsis yuam kev tus nqi, thiab kev ntseeg siab.
Feature 4: Tag nrho cov chaw nres tsheb sib npaug thiab sib faib cov kab sib kis.
Feature 5: Nws siv kev tswj kev sib faib thiab kev sib txuas lus tshaj tawm, thiab nws tuaj yeem siv tau rau ob qho tib si tshaj tawm thiab multicast.
Cov khoom tseem ceeb uas ua rau LAN yog nws lub network topology, nws cov xov xwm sib kis, thiab nws txoj hauv kev los tswj kev nkag mus rau hauv xov xwm.
Cov saum toj no yog cov lus piav qhia txog kev nkag siab ua ntej ntawm LAN coj los ntawm Shenzhen HDV Phoelectron Technology Co., Ltd., cov chaw tsim khoom ntawm cov khoom siv kho qhov muag.
