| Unique Visitor |
A real visitor to a web site.
Web servers record the IP addresses of each visitor, and this is used to determine the number of real people who have visited a web site.
If for example, someone visits twenty pages within a web site, the server will count only one unique visitor (because the page accesses are all associated with the same IP address) but twenty page accesses. |
| URL |

The beginning of the address indicates the type of resource - e.g. http: for web pages, ftp: for file transfers, telnet: for computer login sessions or mailto: for e-mail addresses. Uniform Resource Locator, an HTTP address used by the World Wide Web to specify a certain site. This is the unique identifier, or address, of a web page on the internet.

Many of them cover professional subjects and societies and are rich sources of business information; others are junk and contain little but mindless drivel. |
