Entirna: University campus-a building hrang hrang khawpui khat chhunga awmte thlunzawmna ang hi a ni. Kum 1980 leh 1990 inkar vel khan fiber optics (hrui kal tlanga eng hmanga data thawnna) a rawn lar chhoh khan a rawn piang a. Cable TV company-te hi MAN hmang hmasatu leh ti hmasawntu ber an ni.
4. WAN: Wide Area Network (Ram Huapa Inkalpawhna)
WAN hi network zinga lian ber leh zau ber a ni a, ram pakhat emaw, khawmualpui (continents) hrang hrang emaw a thlunzawm thei a ni. Hmun hla tak taka awmte thlunzawmtu network lian a ni. Entirna: Internet-a khawvel pumpui kan inthlunzawmna hi WAN entirna langsar ber a ni. Kum 1960 tawp lam khan ARPANET (United States Department of Defense) ten bul an țan a. Tunlai khawvelah chuan Cisco Systems hi he lama hmahruaitu leh networking hmanrua siamtu lian ber a ni.
