3.1. one station fails, the entire net- work fails. The most common topologies are presented below, along with information where position the surge protective devices each case. Ring networks are used e. At its end, the bus must have anechoic closure. Typical applications include 10BaseT and 100BaseT, but also Gbit applications.1 Topologies In information technology, devices communicate with one another electrically via cables that can ar- ranged various configurations; these configurations are called “topologies”. Token Ring applications.g. IT terminals Surge protective devices Bus topology Star topology In the star topology, every workstation supplied a separate cable from central star point (HUB or Switch). Typical applications are 10Base2, 10Base5 and ma- chine controllers such Profibus and telecommunic- ation systems such ISDN.3.
