Network Topology

Network topology refers to the physical or logical connection between various nodes in a computer network, including computers, servers, routers, switches and other equipment. It describes the layout and interconnection between various nodes in the network. , as well as the data transmission path in the network. Common network topologies include "star topology", "bus topology", "ring topology", "tree topology" and "mesh topology".

Network topology refers to the physical or logical connection between various nodes in a computer network (including computers, servers, routers, switches, etc.). It describes the layout and interconnection between various nodes in the network, as well as the transmission path of data in the network.

Common network topologies include:

1. Star topology: All nodes are directly connected to a central device (such as a switch, hub), forming a star structure . If the central device fails, it will affect the operation of the entire network.

2. Bus topology: All nodes are connected to a backbone (bus), forming a linear structure. Data is transferred over the bus. If the bus fails, the entire network will be disrupted.

3. Ring topology: All nodes are connected together in a ring order to form a closed loop. Data is transmitted on the ring. Ring topology is relatively rarely used because if a node fails, the entire network will be affected.

4. Tree topology: Nodes are organized hierarchically to form a tree structure. There is a root node, branches connect to child nodes, and child nodes can further connect to other child nodes. Tree topology can provide good scalability and redundancy.

5. Mesh topology: Nodes are connected to each other through multiple connections to form a mesh structure. Mesh topology offers a high degree of redundancy and reliability, but is more expensive.

In addition, there are some hybrid topologies, such as star bus topology, star ring topology, etc., which are combinations of the above basic topologies.

Different network topologies are suitable for different scenarios and needs. Choosing a suitable topology can improve the performance, reliability and manageability of the network.
