What is a web server?

• A. Delivers internet content to users on the internet
• B. Manages email routing
• C. Stores user passwords in a database
• D. Provides DNS resolution

Answer: (A)

A web server is software (often running on a computer) that serves web pages and other content to users over the internet by handling HTTP/HTTPS requests. When you type a URL or click a link, your browser asks the server for the requested resource; the server then sends back the appropriate content, such as HTML, images, or scripts, so your browser can render the page. This delivering of internet content to users on the internet is exactly what a web server does.

Other options describe different kinds of servers or storage tasks: managing email routing is handled by a mail server, storing user passwords in a database is a data-storage task (typically part of an application’s backend, not the web server’s primary role), and providing DNS resolution is done by a DNS server.
