Domain Name - DNS

A domain name is a unique name that is used to identify and locate computers on a network (including the internet), it can be used for websites and/or email addresses. For instance this website's domain name is www.helpwithpcs.com.

All machines connected to the internet have their own IP Address, domain names are just an easier way to access a certain machine, for instance if you had to remember IP Addresses instead of domain names it would be cumbersome.

DNS - Domain Name Server

When you type a domain name into your browser the name is looked up on what is called a domain name server, this server (or servers) points the browser to the IP Address of the machine that is listed under that domain name.
