What role does a web server play?

• A. It hosts websites and delivers web pages to users' browsers
• B. It protects networks from cyber threats
• C. It creates security protocols for data transmission
• D. It stores backup files for online users

Answer: (A)

A web server's primary function is to host websites and deliver web pages to users' browsers. When you access a website, your browser sends a request to the web server, which then processes that request and responds by sending the appropriate web page back to the browser. This central role in the web experience makes web servers essential for providing content to users over the internet.

Other options, while related to internet technology, do not describe the primary function of a web server. For instance, protecting networks from cyber threats typically refers to the role of firewalls or security devices rather than a web server. Similarly, creating security protocols for data transmission involves concepts like SSL/TLS, which are related to encrypting data rather than directly relating to the hosting functions of a web server. Lastly, storing backup files is generally managed by dedicated storage solutions or services, rather than being a specific role of a web server, which focuses on content delivery rather than backup functionalities.
