Raws li lawv cov yam ntxwv architectural, LAN keyboards kuj categorized ua peb hom: khib-mounted, tsau-configuration nrog expansion slots, thiab tsau-configuration tsis expansion slots. Khib-mounted keyboards yog qhov qhib-raws li cov keyboards uas muaj peev xwm ua tau zoo, txhawb nqa ntau hom network xws li Ethernet, Fast Ethernet, Gigabit Ethernet, ATM, Token Ring, thiab FDDI, tab sis lawv kim dua. Ntau lub siab -kawg switches siv lub khib-mounted qauv. Tsau-txheej hloov pauv nrog cov qhov nthuav dav muaj cov chaw ruaj khov thiab ob peb qhov txuas ntxiv. Cov keyboards no txhawb cov hom chaw nres nkoj ruaj khov thiab tuaj yeem nthuav dav los txhawb lwm hom network. Lawv tus nqi yog nruab nrab. Tsau- teeb tsa kev hloov pauv yam tsis muaj qhov nthuav dav txhawb nqa ib hom network nkaus xwb (feem ntau Ethernet) thiab tsim nyog rau LANs hauv kev lag luam me lossis chaw ua haujlwm ib puag ncig. Lawv yog cov pheej yig tshaj thiab siv dav tshaj plaws.
Raws li OSI xya- txheej txheej network qauv, cov keyboards kuj tseem tuaj yeem muab faib ua Txheej Txheej 2 hloov, Txheej 3 hloov, Txheej 4 hloov, thiab lwm yam, mus txog Txheej 7 hloov. Txheej 2 keyboards, uas ua haujlwm raws li MAC chaw nyob, feem ntau yog siv rau hauv kev nkag mus rau hauv lub network thiab cov txheej txheem sib sau ua ke. Txheej 3 keyboards, uas pauv cov ntaub ntawv raws li IP chaw nyob thiab cov txheej txheem, feem ntau yog siv nyob rau hauv cov txheej txheem tseem ceeb ntawm lub network, thiab rau qhov tsawg dua hauv txheej txheej. Qee qhov Layer 3 keyboards kuj muaj Layer 4 switching peev xwm, tso cai rau lawv los txiav txim qhov chaw nres nkoj raws li cov ntaub ntawv chaw nres nkoj raws tu qauv ntawm cov ntaub ntawv ncej. Hloov ntawm Txheej 4 thiab saum toj no yog hu ua cov ntsiab lus - qhib cov keyboards thiab feem ntau yog siv hauv Internet cov chaw zov me nyuam.
