How does the DNS function in internet communication?

• A. It encrypts data for secure transmissions
• B. It translates domain names into IP addresses
• C. It connects users to local networks
• D. It filters unwanted content

Answer: (B)

The Domain Name System (DNS) plays a crucial role in internet communication by translating human-readable domain names, like www.example.com, into machine-readable IP addresses, such as 192.0.2.1. This translation is essential because while people find it easier to remember and use domain names, computers and network devices primarily communicate using numerical IP addresses. When a user types a domain name into their web browser, the DNS acts as a directory, resolving that name to the corresponding IP address, allowing the browser to locate and connect to the appropriate server hosting the website. Thus, this functionality facilitates seamless internet navigation and communication, making it a fundamental component of the overall internet infrastructure.
