        •Bus topology 
  This type of network was widely used in the 1980’s 
  In this configuration every computer (node) shares 
  the networks total bus capacities. 
  In this configuration adding more computers will 
  reduce the access speed on the network. 
  Each computer communicates to other computers 
  on the network independently this is referred to as  
       PEER-TO-PEER networking 
 How a Bus Peer to Peer 
       •Network Works
 All computers on a network have a distinct 
  address just like your house does
 a message would be send from one 
  computer with the address of another 
  computer attached to the message
 The message is broadcasted  to all the 
  computers on the network until the 
  addressed PC accepts the message  
        •How it worked
  The type of wires used for Bus Networks in the 80’s 
  were called Thicknet and Thinnet
  A Thicknet cable (very large about 1 inch in 
  diameter  usually yellow was hung around a room)
  Thinnet cables were connected to the PC’s NIC 
  and a Transceiver. The Transceiver was tapped 
  into the Thicknet cable 
  To stop the message from bouncing back and 
  forward down the wire (known as signal bounce) 
  both ends of the network are terminated with 50Ω 
  resistors 
         •Problems
 One of the main problems with this type of 
  network is that it is not very fault tolerant, a 
  break or defect in the bus would affect the 
  whole network 
        •Ring Topology 
  In Ring topology each node is connected to the 
   two nearest nodes so the entire network forms a 
   circle 
  Data only travels in one direction on a Ring 
   network
