C.1 Resource

A resource is almost anything. `It' can range from a person to an HTML file to a computer to a database or presumably eventually to phone numbers, possibly physical hardware. This generality is a very important concept for the World Wide Web. Really the key thing about a resource is that it can be `identified'. See section C.2 URLs, for more details.

C.2 URLs

A URL or `Uniform Resource Locator' are the essence of the World Wide Web. Approximately, they are addresses through which `resources' can be located. The idea is that almost anything can be given some kind of address in a form that a machine can work with. By defining a set of rules, this can then be converted into a URL. A URL has two parts. The first tells us what rules to use and the second tells us what the address is.

C.4 Link

The term link in LinkController is used for a connection between two resources. It's existance really comes from the `class' or piece of type of computer data which is used to store information about `links'. Properties of a link include:

Within the programs, a link is different from a URL in that it is specifically aimed at checking connections, where a URL just specifies what the connection should be if it is working.
