- Types of network available (continued)
- Ring topology
- Also a peer-to-peer networm because there is no server
- All computers are arranged in a circle
- Data sent by one computer passes around the ring until it reaches the correct computer
- Advantages
- Network is not dependent on a central computer
- Each computer has the same access as the others
- Disadvantages
- If there is a break in the connection the whole network fails
- Faults are difficult to locate
- Impossible to keep the network running whilst equipment is added or removed
- Also a peer-to-peer networm because there is no server
- Bus topology
- All devices connected to the network are connected to a common shared cable called the backbone.
- Advantages
- Cost-effective due to small amount of cable needed
- Simple cable runs makes it easy to install
- Easy to add extra devices to the network
- Disadvantages
- If more than 12 devices are connected, the performance of the network is degraded
- If there is a break in the backbone cable, then the network cannot be used
- Star topology
- Uses a central connection point to connect all devices on the network together
- Advantages
- Fault tolerant
- Load tolerant
- Easy to add extra computers
- Disadvantages
- Higher cost
- Dependence on the central hub, switch or router
- Ring topology
