Horumarinta guud iyo adeegsiga tignoolajiyada shabakada, horumarinta furayaasha ayaa sidoo kale soo maray isbedel weyn.Dabeecadaha ugu horreeya waxay ka soo baxeen beddelaadyo aad u fudud oo waxay noqdeen lakabka 2 furayaasha, ka dibna lakabka 2 waxay beddeleen lakabka 3.Haddaba, waa maxay aLakabka 3 beddelka?

Lakabka 3 wareegyadadhab ahaantii waa Lakab 2 tignoolajiyada beddelka + Lakabka 3 tignoolajiyada gudbinta.Macnuhu maaha inay jiraan "saddex lakab" oo furayaasha ah.Alakabka 3 bedelwaa bedel leh qaar ka mid ah hawlaha router.Ujeedada ugu muhiimsan eeLakabka 3 beddelkawaa in la fududeeyo isweydaarsiga xogta gudaha LAN weyn.Hawsha habaynta ee ay leedahay waxa kale oo ay bixisaa adeegyo ujeedadan, waxaana la marin karaa hal mar oo la soo gudbin karaa dhowr jeer.

Tignoolajiyada beddelka ee dareenka dhaqameed waxay ku shaqeysaa lakabka labaad ee moodeelka caadiga ah ee shabakadda OSI — lakabka isku xirka xogta, halka tignoolajiyada beddelka saddex lakab ay dhammaystirto gudbinta xawaaraha sare ee xirmooyinka xogta lakabka saddexaad ee qaabka shabakadda.Xidhiidhada wakhtiyada ah sida gudbinta baakidhka xogta si dhakhso ah ayaa loo dhamaystiraa qalab, laakiin adeegyada sida hagaajinta macluumaadka, dayactirka miiska dajinta, xisaabinta dariiqa, iyo xaqiijinta marinka waxaa dhamaystira software.Ma ogaan karto oo kaliya shaqada marinka shabakada, laakiin sidoo kale waxay hubisaa waxqabadka shabakada ugu fiican ee xaaladaha shabakadaha kala duwan.
