Ma PC a Industrialnthawi zambiri amakhala ndi madoko apawiri a LAN (Local Area Network) pazifukwa zingapo: Network Redundancy ndi Kudalirika: M'malo ogulitsa mafakitale, kudalirika kwa maukonde ndi kukhazikika ndikofunikira kwambiri. Pogwiritsa ntchito madoko apawiri a LAN, ma PC amakampani amatha kulumikizana ndi maukonde osiyanasiyana nthawi imodzi kudzera pamanetiweki awiri osiyana kuti apereke zosunga zobwezeretsera.
Ngati maukonde amodzi akulephera, winayo atha kupitiliza kupereka kulumikizana kwa ma netiweki, kuwonetsetsa kulumikizidwa ndi kukhazikika kwa zida zamakampani. Liwiro losamutsa deta ndi kusanja kwa katundu: Ntchito zina zamafakitale zimafunikira kusamutsa kwa data kochulukirapo, monga makina opanga makina kapena kuyang'anira nthawi yeniyeni.
Pogwiritsa ntchito madoko apawiri a LAN, ma PC am'mafakitale amatha kugwiritsa ntchito ma netiweki onsewa kusamutsa deta nthawi imodzi, potero amakweza liwiro losamutsa deta komanso kusamutsa katundu. Izi zimathandiza kuti pakhale kukonzanso bwino kwa deta yochuluka ya nthawi yeniyeni komanso kupititsa patsogolo ntchito za zipangizo zamakampani.
Kudzipatula kwa ma netiweki ndi chitetezo: M'malo ogulitsa, chitetezo ndichofunikira. Pogwiritsa ntchito madoko apawiri a LAN, ma PC ogulitsa mafakitale amatha kukhala paokha polumikiza maukonde osiyanasiyana kumadera osiyanasiyana achitetezo. Izi zimalepheretsa kuwukira kwa ma netiweki kapena pulogalamu yaumbanda kuti isafalikire ndikuwongolera chitetezo cha zida zamafakitale.
Mwachidule, madoko apawiri a LAN amapereka ma netiweki redundancy, kuthamanga kwa data ndi kusamutsa katundu, kudzipatula pa intaneti ndi chitetezo kuti akwaniritse zofunikira pazovuta zama network m'malo ogulitsa.
