The correct answer is: D. Domain Name System
A domain name system (DNS) is a hierarchical naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participants. Most prominently, it translates easily memorized domain names to the numerical IP addresses needed for locating computer services and devices with the underlying network protocols. By translating a human-friendly name to a numerical IP address, the DNS service makes it possible for Internet users to locate web pages and other resources by name.
The DNS system is a distributed database, which means that it is not stored in one central location. Instead, it is stored on a number of different servers around the world. This makes it more reliable and scalable than a centralized system.
When a user enters a domain name into their web browser, the browser sends a request to a DNS server. The DNS server then looks up the IP address associated with the domain name and returns it to the browser. The browser then uses the IP address to connect to the web server.
The DNS system is an essential part of the Internet. It allows users to access web pages and other resources by name, rather than by IP address. This makes it easier for users to remember and use the Internet.
The following are the other options and their explanations:
- A. Distributed Name System: This is not the correct answer because the DNS system is not a distributed name system. It is a hierarchical naming system.
- B. Data Name System: This is not the correct answer because the DNS system is not a data name system. It is a domain name system.
- C. Dynamic Name System: This is not the correct answer because the DNS system is not a dynamic name system. It is a hierarchical naming system.
- E. None of the above: This is not the correct answer because the DNS system is a domain name system.
