Hi,
Could you please clarify your questions with more details? Like if it is related to any MS product or something else?
Per internet searching, client-server model/architecture, is a distributed application framework dividing tasks between servers and clients, which either reside in the same system or communicate through a computer network or the Internet.
The client relies on sending a request to another program in order to access a service made available by a server. The server runs one or more programs that share resources with and distribute work among clients.
Hope this helps and please help to accept as Answer if the response is useful.
Thanks,
Jenny
