5. What is Domain Naming System and how is it different from IP addressing system?
Ans: Every computer connected to the Internet should have a unique address. The ICANN has designed a system to provide a unique address to each computer in the form of numbers or characters. The character based addressing system is known as Domain name, whereas the number based addressing system is known as IP address. Domain names are easier to remember that IP addresses since a name has a strong correlation with the website. The Domain Name System (DNS) serves as a directory for the web by locating and addressing devices in a worldwide network.
