What's the difference between the client version and the web version?

The client version is C/S and the web version is B/S, with different structures. The client version has certain requirements for the performance of the client, and the upgrade also requires the client to upgrade the client software synchronously, but the network requirements are low; The web version requires higher server performance, and the upgrade is all done by the server. Users only need a browser, but they have higher requirements for the network.
