Network Topology - arrangement of internet where device supposed to be two type of network topology: 1. Logical - how device appear to be connected to each other example; packet tracer. 2. Physical- actual interconnection with wire and cables(actual connected). point-to-point:  two device directly connected together figure 1(point to point topologies) example; can be PC and PC, PC to switch + sending information is faster + no traffic - cannot connect more device - the cable broke will affect the others. BUS use (1 backbone) 1 cable connected to several devices (it can be PC, Printer, laptop)   figure 2(BUS topology) +not expensive because only use one cable +easy to install another device -if one PC is broke it will affect others, because of using 1 cable. -there will be traffic if many hosts want to send information at the same time. STAR it uses a switch, hub or a router in the middle to connect to any device   ...
