What is a topology?
The arrangement of computers in a network.
Examples of topologies
Star
Pro: If one system breaks, it does not effect the network
Con: it is dependent of the central computer, and wiring is expensive.
Ring
Pros: Easy to access/transmit data. Doesn't require server and works better than a star.
Cons: One malfunctioning node can stop the whole network. It is slower than Ethernet too. Moving, adding, and changing devices can be straining.
Bus
Pros: If one node fails, the others are not affected. Simple and easy to set up.
Cons: If the cable malfunctions, the network goes down. Cables and number of nodes are limited.
Hierarchial
Cons: If one node fails, the others fail as well
Pros: Data can be easily shared as all nodes are interconnected to one another.
