What is the network topology? What kinds are common?

Network topology refers to the physical layout of various devices interconnected by transmission media, that is, how computers and other devices in the network are connected.

Common network topologies mainly include star structure, ring structure, bus structure, distributed structure and tree structure.

Extended data:

1, star network topology

The star network topology is characterized by control center and centralized control, and each site is connected with the central station through point-to-point links.

2. Ring topology

Ring topology is that all stations are connected into a closed ring through communication media, and all nodes are connected into a network through repeaters, which are connected end to end. The communication mode of ring network is that one station sends information, and other stations on the network can receive it completely.

3. Bus topology

The bus topology is that all stations in the network share a bidirectional data channel.

4. Tree structure

The tree structure is an extension of the bus structure, and the transmission medium is an unclosed branch cable. It is mainly used in the hierarchical structure composed of multiple networks, and its characteristics are roughly the same as those of the bus-type network.
