用于修飾或說明其中具有多個數據終端的一種通信網絡。 Pertaining to a communications network having several data terminals.
歐姆電阻單位，一段導體兩端的電位差為伏特時產生一安培電流，那么這段導體的電阻就等于歐姆 A unit of electrical resistance equal to that of a conductor in which a current of one ampere is produced by a potential of one volt across its terminals.
說明包含或支持（通常理解為在同一地點而不是由通信鏈路連接）多個終端的設施等。 Including or supporting more than one terminal(usually understood to beat the same location rather than joined by communications links).
