Network Topologies Bus Topology  Star Topology 

Transmission Medium Twisted pair  Coaxial cable 

Bus Topology Back Bone  Taps  Nodes  Terminator  Repeater 

Bus Topology Layout

Advantages Cheap  Easy to maintain  Easy to add new nodes  Great for small networks  Less usage of cable 

Disadvantages Obsolete Method  Crash of Backbone crashes whole network  Lack of Dedicated Lines  Limited No. of Nodes 

Star Topology Hub or Switch  Medium  LAN Card 

Star Topology layout

Advantages Ease of configure  Easy to maintain  Less Expensive 

Disadvantages Failure of Hub means failure of Network  Extensive cabling than Bus Topology 

LAN configuration in Star Map out the network  Determine the Optimum cable lengths  Determine the Optimum place for Hub  Connect each computer to Hub using cable  Lights on Hub and LAN Card means the connection is OK. 
