Software classification:
1, classified by application structure
The structure is divided into C/S structure (client/server structure) and B/S structure (browser and server structure), both of which support remote applications at present. CS is applied under poor network conditions, while BS is applied under good network conditions. In the past, the biggest problem of CS was maintenance, but at present, similar manufacturers solve this problem through automatic updating, so there is little difference in this respect.
