What are the common network topologies?

Common network topologies include: 1. Star topology; 2. Bus topology; 3. Ring topology; 4. Tree topology; 5. Mesh topology; 6. Hybrid Topology. Among them, the mesh topology is the most widely used and is not affected by bottleneck problems and failure problems.

Six common topologies in computer networks:

(Learning video sharing: Programming video)

Star topology

The star structure is a center with multiple sub-nodes. It has a simple structure, convenient connection, relatively easy management and maintenance, and strong scalability. The network delay time is small and the transmission error is low. There is no problem with the center, and there is no problem with the general network. If the center fails, the network will have problems. At the same time, the sharing capability is poor and the communication line utilization is not high.

Bus topology

Bus topology All devices are connected to a connection medium. The bus structure requires a small number of cables and short cable lengths, making wiring and maintenance easy. Multiple nodes share a transmission channel, and the channel utilization rate is high. But not looking for diagnostic faults.

Ring topology network

A ring topology network is a closed ring formed by nodes. Fewer workstations, saving equipment. Of course, this will cause problems with one node and cause network problems, and it will be difficult to diagnose faults.

Tree topology

The tree topology evolved from the bus topology. It is shaped like an inverted tree, with the root at the top and branches below the root. Each branch can be With sub-branches, the root of the tree receives the data sent by each site, and then broadcasts it to the entire network. Easy to expand and easy to diagnose errors, but demanding on roots.

Mesh topology

is the most widely used. Its advantage is that it is not affected by bottleneck problems and failure problems. If there is a problem with the line one day, other lines can be used, but it is too complicated and costly. .

Hybrid topology

is to use two or more of the above together. For example, the star bus type, star ring type, etc. are mostly used.
