Answer:
Client-Server Model
Step-by-step explanation:
The Client-Server model structure divides tasks between clients, which are the the requesters of services, and servers, which are the providers of services or resources.
Information or data, is usually stored securely in the backend or server machine. Users then access these information by communicating with the server over a computer network.
Example is when a user requests a webpage using a website's address. The server gets the request from the client and finds the page in the database residing in the backend, then serves it up to the user when found.
