DNS stands for Domain Name System and its a translation table for IP addresses into a readable domain name. There are various types of DNS records making it possible for the machines to understand what exactly the DNS record represents. Basically, it's a road sign that both tells you the address/direction and what its for. For example, when you see the sign for the highway, it shows the direction and what you can expect in the other end, a highway or a mail server...
