Correct Answer - Option 2 : DNS

The correct answer is DNS.

  • The Domain Name System is a hierarchical and decentralized naming system for computers, services, or other resources connected to the Internet or a private network.
  • It associates various information with domain names assigned to each of the participating entities. 
  • The Domain Network System (DNS) protocol helps Internet users and network devices discover websites using human-readable hostnames, instead of numeric IP addresses.
  • The Domain Name System translates human-readable domain names (for example, www.amazon.com) to machine-readable IP addresses (for example, 192.0. 2.44).

Types of Protocols:

  • Transmission Control Protocol (TCP)
  • Internet Protocol (IP)
  • User Datagram Protocol (UDP)
  • Post office Protocol (POP)
  • Simple mail transport Protocol (SMTP)
  • File Transfer Protocol (FTP)
  • HyperText Transfer Protocol (HTTP)
