Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	True
B	False
C	Either A or B
D	None of the above

Explanation:

Detailed explanation-1: -DNS lets users connect to websites using domain names instead of IP addresses.

Detailed explanation-2: -The DNS server returns the IP address, and the browser connects to the webpage that then appears on your screen. End users are unaware of the background tasks required to make the system work. If the DNS server is unavailable, the browser has no way of acquiring the website’s IP address, so it returns an error.

Detailed explanation-3: -Another method for bypassing DNS is to use the hosts file on your local computer. The hosts file contains domain name to IP address mappings. These mappings mimic the function of a DNS server, and allow you to “trick” your computer into associating a domain name with a particular IP address.
