| What is a topology? | A topology refers to the layout of the network components: the cabling and position of the nodes. |
| What is bus topology? | The computers and other devices are attached at each end to present reflection of signals |
| What are the advantages of bus topology? | Easy to set up Cheap |
| What are the disadvantages of bus topology? | Problems with the back bone can bring the whole network down Limited distance can be covered Many data collisions slow the network down |
| What is star topology? | Client machines are connected to a central switch or hub which is usually in turn connected to one or more servers |
| What are the advantages of star topology? | Robust Fewer data collisions (faster) |
| What are the disadvantages of star topology? | More expertise needed to maintain Can be expensive to set up |
| What is ring topology? | Data passes through each node, carried in units called tokens. Traffic is one way so prevents collision |
| What the advantages of ring topology? | Very fast (no collisions) |
| What are the disadvantages of ring topology? | Problems with backbone bring the whole network down Data passes through every node making it very vulnerable to malfunction |
