Every computer connected to the Internet is identified by a unique four-part string, known as

  • A.IP address
  • B.Host name
  • C.Domain name
  • D.None of the above

Answer: A

The string is the IP address.

Every device on the Internet has an Internet Protocol address. In IPv4 it is written as four numbers from 0 to 255 separated by dots, such as 192.168.1.1, which is the four-part string the question describes.

A domain name such as tpsc.tripura.gov.in and a host name are human-readable labels. The Domain Name System translates them into IP addresses, so they are not the numeric identifier itself.
