The correct answer is: A. 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 domain names into numerical IP addresses, the Domain Name System makes it possible for humans to remember the names of websites and other computer services without the need to remember the numerical addresses that computers use to identify each other.
The Domain Name System is a distributed database, which means that it is not stored in one place. Instead, it is stored on a network of computers called name servers. When you type a domain name into your web browser, your computer sends a request to a name server. The name server looks up the IP address for the domain name and sends it back to your computer. Your computer then uses the IP address to connect to the website.
The Domain Name System is a critical part of the Internet. It allows people to access websites and other online resources by using easy-to-remember names instead of numerical IP addresses.
The other options are incorrect because:
- B. Divided Name System is not a real term.
- C. Distributed Name System is a real term, but it is not the same as the Domain Name System. A distributed name system is a type of name system that is distributed across multiple computers.
- D. Dynamic Name System is a real term, but it is not the same as the Domain Name System. A dynamic name system is a type of name system that allows the IP address of a resource to change over time.
