Domain Naming Service(DNS)
It is very difficult to remember a set of numbers (IP address) to connect to the Internet. The Domain Naming Service(DNS) is used to overcome this problem. It maps one particular IP address to a string of characters. For example, www.java2novice.com implies com is the domain name reserved for US commercial sites, java2novice is the name of the company and www is the name of the specific computer, which is java2novice's server.
