Network topology refers to the arrangement of different elements (links, nodes, etc.) in a computer network. Below are the main types of network topologies:
- All devices share a single central cable (backbone).
- Data travels in both directions but can collide.
- Failure of the backbone affects the whole network.
- Easy to install.
- Requires less cable.
- Difficult to troubleshoot.
- Performance degrades with heavy traffic.
- All devices connect to a central hub or switch.
- The hub manages network communication.
- Easy to install and manage.
- Failure of one device does not affect others.
- Failure of the hub affects the whole network.
- Requires more cable than bus topology.
- Devices are connected in a circular manner.
- Data travels in one direction (unidirectional) or both (bidirectional).
- Reduces data collisions.
- Good for high-speed networks.
- Failure of one node can break the network.
- Difficult to troubleshoot.
- Every device is connected to every other device.
- Provides multiple paths for data transmission.
- High redundancy and reliability.
- Failure of one node does not affect the entire network.
- Expensive due to a large number of connections.
- Complex to set up and maintain.
- A combination of bus and star topologies.
- Devices are connected in a hierarchical manner.
- Scalable and easy to expand.
- Fault isolation is easier.
- Failure of the main backbone can affect the network.
- Requires more cable.
- A combination of two or more different topologies.
- Used in large networks where different requirements exist.
- Flexible and scalable.
- Efficient performance.
- Complex design and high cost.
- Requires advanced network management.
