Since it is difficult to memorise IP addresses, so for convenience the alphanumeric address is used for naming
          the websites. When we type the alphanumeric address in the address bar of the web browser, then, the DNS
          translates it into an IP address and requests the web server to locate the specified file on its site.
        Some common Top-Level Domains are as follows:

           • IP (Internet Protocol) Address: It is a unique logical address of a device that helps identify a device at the
          time of sending and receiving data in a Network. It is made up of numbers or characters. Remembering these
          numeric values to access a specific website is a difficult task, so these numbers are given sensible textual names
          called web addresses.
