Can anyone explain HOW and WHY the devices on the image ( PC,Routers,Hubs and Servers) are connected with each other in that way and with those kind of cables ? I have an assignment to similarly connect three cities with the simulator but at first I must understand this given example network . I'll appreciate anyone who can help me and explain this network in detail ( especially the cables that are used to connect the devices ) . I apologise if I made any grammatical or vocabulary errors . I'm waiting for any helpful replies :)
