- 1Line/Bus networksData is sent to and from the server, along a line of cables
All terminals are connected using a central line - 2Cons - Bus Networks With lots of signals the system slows down. If central cable fails, so does the whole systemPros - Bus Networks
Cheap - 3Ring Networks Similiar to bus,but connected in a ringData flows in one direction ONLY
- 4Pros of Ring Network Cheap Fast - because data flows in one directionCons of Ring Networks
-With a lot of users the system becomes slow.
Failure of the ring brings down the whole network down.
-Data flows in one direction ONLY - 5How many network topologies are there? Name them!There are FIVE network topologies:
Star
Mesh
Tree
Ring
Bus - 6Wireless networks can be thought of a type of star network without cables.-Give access to a central computer
-Often used when there are a large number of workstations that need connecting
-Each worksation is connected to the central computer (either mainframe or server) - 7Pros of star network -Performance on part of the network isnt affected by others -Easy to add more workstationsCons of star network
Failure in the central computer will mean failure to the whole network
Uses alot of cabling if a wired.
