A name helps classify an idea or object and creates a label under which similar ideas or objects can be placed. Names, once adopted in general use, aid communication by implying a longer description to a short label.
Names are important to the Internet as well.
It is names which allow us to identify places and people within that electronic environment. Internet names are so important that many companies now identify themselves as much by their internet name as their corporate logo. Obviously, on the Internet, there's a lot in a name. Such a name actually identifies a computer network associated with an organization. For example, unt.edu is part of all the addresses used within the University of North Texas' Internet network.
