1. There are 4 main network topoligies

   • The mesh topogy can withstand high traffic and if one node fails there is always another route the data can go,however cabling costs are high and alot of wiring is needed
   • Ring
     • prevents data collisions , if one node goes down the whole network goes down
   • Bus
     • Bus network, it is cost effective and quick to set to set up because of the simplicity of the network data collisions
   • • Star
   • Mesh
   • In a star network there is a fast network speed and it is possible to add more computers on the network, extra hardware is required and a switch hub manager may need to be hired

2. Lan- Local area network, where the networks are close to each other for example a school network

3. Wan- Wide are network. the computer systems are far from each other for example the internet
