Study Notes
Network Topology
- Network Topology is the configuration or layout of a network.
- It defines the paths between any two points in a network.
- It influences network performance, particularly availability, speed, and traffic congestion.
Basic Topology
- Mesh Topology
- Provides multiple paths between end nodes.
- Failure of an intermediate node may slow down network traffic but will not stop it as long as alternative paths exist.
- All nodes are connected to each other.
- Bus Topology
- All devices are connected to a single cable called a bus.
- Data is transmitted in both directions.
- Relatively inexpensive to implement since fewer cables are required.
- Star Topology
- All devices are connected to a central device (e.g. hub or switch).
- Data is passed through the central device.
- Easy to add or remove devices.
- Ring Topology
- Devices are connected in a closed loop.
- Data travels in one direction around the ring.
- Offers high bandwidth and fault tolerance.
