Star structure means that all workstations are connected into a network in star mode. The network has a central node, and other nodes (workstations and servers) are directly connected to the central node. This structure is centered on the central node, so it is also called a centralized network. It has the following characteristics: simple structure, easy to manage; Simple control, easy to build network; Network delay time is small, transmission error is low. But the disadvantages are also obvious: high cost, low reliability and poor resource sharing capacity.
The main advantages of star topology are:
1. Simple structure and easy management and maintenance;
2. Flexible reconfiguration;
3. Convenient fault detection and isolation;
4. Simple control and convenient network construction;
5. Low network delay time and low transmission error;
The main disadvantages of star topology include:
1. High cost and low reliability;
