   • advantages= Cheap to install.
   • disadvantages
     • High chance of castatrophic failure.
     • Lots of collisions.
     • Slows down as more computer are added.

5. Ring Topology

   • Advantages
     • Cheap to install
     • No collisions(fast)
   • Disadvantages
     • High chance of catastrophic failure
     • Difficult to expand

6. Star Topology

   • Advantages
     • Low chance of failure.
     • No collisions
   • Disadvantages
     • Expensive
     • Depends a switch

7. Ip addressing

   • An Ip address is a unique value assigned to every computer on a network ,used to identify it.
