What are the commonly used topologies in local area networks?

The commonly used topologies in local area networks are bus, star and ring. LAN can realize file management, application software sharing, printer sharing and other functions. The LAN can effectively protect data security and ensure the normal and stable operation of the LAN network.

Star structure

In this structure of the network, workstations are connected in a star shape. Each node device in the network is centered on the central node and connected to the center through connecting lines. Nodes are connected, and if a workstation needs to transmit data, it must first pass through the central node.

Since in this structure of the network system, the central node is the control center, and the communication between any two nodes only takes two steps at most, so the transmission speed is fast, the network configuration is simple, and the network construction is Easy and convenient to control and manage.

However, this kind of network system has low network reliability and poor network sharing capabilities. Once the central node fails, the entire network will be paralyzed.
