- Network Topologies, Protocols and Layers
- Topology
- Ring Network
- Each device is connected to two other devices.
- Each packet of data on the network travels in one direction.
- It can transfer data quickly, even if there is a lot of devices because there is no data collisions
- if the main cable or any device fails, then the whole network will fail
- Bus Network
- All devices are connected are joined to one cable
- Easy to install and is cheap to
- Every device on the network sees all of the data on the network, which is a security risk
- Easy to install and is cheap to
- At the end of each cable is a terminator to prevent the signal being reflected
- All devices are connected are joined to one cable
- Easy to install and is cheap to
- Every device on the network sees all of the data on the network, which is a security risk
- Easy to install and is cheap to
- If the main cable fails, the network goes down
- When more devices are connected it loses performance
- All devices are connected are joined to one cable
- All devices are connected are joined to one cable
- Star Network
- Each device has its own cable that connects to a hub
- It is very reliable and it is high performing as no data collisions can occur
- It is expensive as it uses lots of cables
- Extra hardware is required which adds to cost
- If the Hub fails, the whole network goes down
- Extra hardware is required which adds to cost
- It is expensive as it uses lots of cables
- It is very reliable and it is high performing as no data collisions can occur
- Each device has its own cable that connects to a hub
