Computing Topology Revision
Cards in this deck (10)
- 1What is a topology?A topology refers to the layout of the network components: the cabling and position of the nodes.
- 2What is bus topology?The computers and other devices are attached at each end to present reflection of signals
- 3What are the advantages of bus topology?Easy to set up
Cheap - 4What 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 - 5What is star topology?Client machines are connected to a central switch or hub which is usually in turn connected to one or more servers
- 6What are the advantages of star topology?Robust
Fewer data collisions (faster) - 7What are the disadvantages of star topology?More expertise needed to maintain
Can be expensive to set up - 8What is ring topology?Data passes through each node, carried in units called tokens. Traffic is one way so prevents collision
- 9What the advantages of ring topology?Very fast (no collisions)
- 10What 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
