1. Miyezo yosiyanasiyana yogwirira ntchito: Masinthidwe a Layer 2 amagwira ntchito pagawo la ulalo wa data, ndipo masiwichi a Layer 3 amagwira ntchito pa netiweki. Masiwichi a Layer 3 samangokwaniritsa kutumizira mwachangu kwa mapaketi a data, komanso amakwaniritsa magwiridwe antchito abwino kwambiri a netiweki malinga ndi kusiyanasiyana ...

Ma transceivers opangira mafoni a mdziko lathu adakula mwachangu ndi chitukuko chamakampani owunikira. Kuchokera ku analogi kupita ku digito, kenako kuchokera ku digito kupita ku tanthauzo lapamwamba, iwo akupita patsogolo mosalekeza. Pambuyo pazaka zambiri zaukadaulo, iwo ali ndi ...

Ndi chitukuko cha makampani olankhulana komanso kudziwitsa za chuma cha dziko, msika woyendetsedwa ndi ma ring network wakula pang'onopang'ono. Ndiwotsika mtengo, wosinthika kwambiri, wosavuta komanso wosavuta kugwiritsa ntchito. Ukadaulo wa Ethernet ...

Ntchito ya ma transceivers a fiber optic ndikusintha pakati pa ma siginecha owoneka ndi ma sign amagetsi. Chizindikiro cha kuwala chimalowetsedwa kuchokera ku doko la kuwala, ndipo chizindikiro chamagetsi chimachokera ku doko lamagetsi, ndi mosemphanitsa. Ndondomekoyi ili pafupifupi ngati ...

Kodi IEEE 802.3 ndi chiyani? IEEE 802.3 ndi gulu logwira ntchito lomwe linalemba muyeso wa Institute of Electrical and Electronics Engineers (IEEE), womwe umatanthawuza kulamulira kwapakati (MAC) pamagulu onse akuthupi ndi a data a Ethernet waya. Izi nthawi zambiri zimakhala ...

Optical fiber transceiver ndi chipangizo chotsika mtengo komanso chosinthika. Zomwe zimagwiritsidwa ntchito nthawi zambiri ndikusintha ma sign amagetsi mumagulu opotoka kukhala ma siginecha owoneka. Nthawi zambiri amagwiritsidwa ntchito mu zingwe zamkuwa za Ethernet zomwe sizingaphimbidwe ndipo zimayenera kugwiritsa ntchito ulusi wa kuwala kuti ...

Kodi Ring network redundancy ndi chiyani? Netiweki ya mphete imagwiritsa ntchito mphete yosalekeza kuti ilumikizane ndi chipangizo chilichonse. Zimatsimikizira kuti chizindikiro chotumizidwa ndi chipangizo chimodzi chikhoza kuwonedwa ndi zipangizo zina zonse pa mphete. Kuchulukitsa kwa ma netiweki a mphete kumatanthawuza ngati kusinthaku kumathandizira ...

Kodi Network Topology Network topology imatanthawuza mawonekedwe owoneka bwino monga kulumikizidwa kwapa media osiyanasiyana, zingwe zapaintaneti, ndikukambilana mosapita m'mbali kuyanjana kwa malekezero osiyanasiyana pamanetiweki pobwereka ...

STP ndi chiyani? STP (Spanning Tree Protocol) ndi njira yolumikizirana yomwe imagwira ntchito pagawo lachiwiri (data link layer) mu mtundu wa OSI network. Ntchito yake yayikulu ndikuletsa malupu omwe amayamba chifukwa cha maulalo ochulukirapo pama switch. Amagwiritsidwa ntchito kuonetsetsa kuti pali ...

Kodi mphepo yamkuntho yowulutsa ndi chiyani? Mphepo yamkuntho yowulutsa imangotanthauza kuti data yowulutsa ikasefukira pa netiweki ndipo sichingasinthidwe, imakhala ndi kuchuluka kwa bandwidth ya netiweki, zomwe zimapangitsa kuti ntchito zanthawi zonse zisamayende bwino, kapena kufa ziwalo kwathunthu ...
