Which component is typically used to host and respond to web requests on a network?

• A. Web server
• B. Email server
• C. DNS server
• D. FTP server

Answer: (A)

The web server is the component that hosts websites and responds to web requests. It runs on a machine in the network and listens for HTTP or HTTPS requests from clients like browsers. When you type a URL, your browser resolves the domain to an IP, connects to the web server on the appropriate port (typically 80 or 443), and sends a request. The web server then processes that request, retrieves the requested content (whether static files or dynamically generated data), and sends back the HTTP response with the page to display. This is different from the other services: an email server handles mail protocols (SMTP, IMAP/POP3), a DNS server translates domain names to IP addresses, and an FTP server facilitates file transfers.
