Study Notes
Star Topology
- Computers are connected to a central hub.
- Advantages: easy to add new nodes, central node facilitates network monitoring.
- Disadvantages: Hub failure affects entire network.
Bus Topology
- All computers and devices are connected to a single cable.
- Linear bus topology is a specific type with two endpoints.
- Advantages: simple installation, saves cable resources, node failure does not usually affect the network.
- Disadvantages: Bus fault impacts entire network, low security due to broadcasting.
Ring Topology
- Each computer is connected to two other computers, forming a closed loop.
- Advantages: saves cable resources.
- Disadvantages: Difficult to add new nodes, requires ring interruption for new node installation.
Tree Topology
- Uses a hierarchical structure with a root node, and other nodes branching from it.
- Advantages: multiple star networks can be combined easily, facilitating expansion.
- Disadvantages: Fault on a higher-level node is more severe.
Mesh Topology
- All nodes are connected to each other directly, forming a point-to-point connection.
Partial Mesh Topology
- Some systems have full mesh connections, while others connect to only two or three devices.
- Advantages: Lower cost compared to full mesh.
- Disadvantages: Lower reliability compared to full mesh.
Full Mesh Topology
- Every node is directly connected to every other node.
- Advantages: High reliability and high communication efficiency.
- Disadvantages: High cost due to many physical ports and cables, difficult to expand.
