What is the primary role of a web server?

The primary role of a web server is to host and serve web content. This involves handling HTTP requests from clients, such as web browsers, and delivering the requested web pages, images, videos, and other resources. When a user types a URL into their browser, it sends a request to the web server that corresponds to that URL. The server then processes this request, retrieves the necessary files, and sends them back to the client. This interaction is fundamental to how users access information on the internet, making the web server a crucial component of the web infrastructure.

The other choices highlight functions that, while important in their own right, do not specifically encapsulate the primary function of a web server. Storing and managing databases is more aligned with database servers, transferring files between computers pertains to file servers, and connecting multiple networks relates to networking devices like routers. Therefore, the specific role of hosting and serving web content sets web servers apart as essential tools for delivering online experiences.
