Daim npav network (network adapter, daim npav network, NIC - Daim npav Network sib tshuam) feem ntau hu ua cov khoom tshwj xeeb ntawm lub koos pij tawj uas muab kev sib txuas lus thiab xa cov ntaub ntawv ntawm ob peb lub khoos phis tawj hauv lub network.
Network phaib faib ua:
- kev koom ua ke ntawm motherboard (feem ntau hauv laptop);
- sab nraud, xav kom muaj kev sib txuas nrog lub khoos phis tawm.
Cov npav xaib sab nraud, sib txawv, sib txawv hauv txoj hauv kev lawv tau txuas rau lub khoos phis tawm thiab lub npav los ntawm cov ntaub ntawv no sib raug zoo ntawm lub motherboard thiab lub network card. Niaj hnub no, cov ntawv sib txuas tas li yog daim npav ua ke nrog cov sib txuas khub sib txuas thiab wireless.
Cov yam ntxwv tseem ceeb ntawm daim npav network yog:
- ntsis qhov tob - 8, 16, 32 thiab txawm tias 64 me me;
- cov ntaub ntawv tsheb npav - ISA, EISA, VL-Bus, PCI;
- maub los microcircuit (nti);
- kev txhawb nqa rau cov khoom xaib sib kis nruab nrab - BNC, RJ45, AUI;
- nrawm;
- FullDuplex;
- MAC chaw nyob.
Qhov sib txawv hauv lub interface txiav txim siab qhov sib txawv hauv kev teeb tsa cov npav network, txawm hais tias feem coob ntawm cov khoom siv niaj hnub no txhawb nqa Plug & Play thev naus laus zis.
Cov tsav tsheb uas nquag muaj nrog rau cov kev khiav hauj lwm tso cai rau koj siv tag nrho cov haujlwm yooj yim ntawm lub cim tshiab ntawm cov hloov kho network. Cov tsav tsheb uas muab los ntawm lub chaw tsim khoom ntawm lub npav network muaj ntau yam ntawm cov ntsej muag.
Ntawm daim ntawv tshwj xeeb yog daim npav raws li USB technology, uas ua kom zoo dua thiab siv tau yooj yim. qhov yuav tsum muaj hauv qhov no yog qhov kev txhawb nqa ntawm USB 2.0 version los ntawm lub koos pis tawj ntawm niam.
Kev sib cav ntxiv thaum xaiv qhov network card tuaj yeem yog:
- Txhawb nqa rau adapter siv khoos phis tawm ROM technology, uas muab lub peev xwm khau raj lub computer tsis muaj qhov nyuaj tsav hla lub network;
- kev txhawb nqa los ntawm daim npav ntawm Wake On Lan thev naus laus zis, uas yog lub luag haujlwm rau kev ua haujlwm ntawm tig lub computer hla lub network;
- txheej txheej rau cov vaj huam sib luag nram qab ntawm xaiv qauv npav.
Pom zoo NIC tuam ntxhab yog Intel thiab 3Com. Kuj tseem ceeb yog cov khoom ntawm CNet, LG, Surecom, Allied Telesyn, B-Txuas thiab SMC.
