The World Wide Web and HTTP-based pages predominantly use which architecture?

• A. Client-Server Architecture
• B. Client-based Architecture
• C. Middleware
• D. Software as a Service

Answer: (A)

The World Wide Web and HTTP-based pages primarily rely on a client-server model: a user’s browser acts as the client that requests resources (like HTML, images, or APIs) from a server that hosts those resources and processes the requests. The server responds with the needed content, which the browser then renders. This setup is why HTTP works as a request–response protocol between clients and servers, even though modern web apps often run more logic in the browser; the fundamental architecture is still a split between clients and servers delivering and handling resources. The other options don’t describe this structure: client-based architecture implies most work happens on the client with little centralized resource hosting; middleware is just a supportive layer between clients and back-end services; and Software as a Service is a delivery model, not the architectural pattern of the web itself.
