URL stands for "Uniform Resource Locator". It is a draft standard for
specifying an object on the Internet, such as a file or newsgroup.
URLs look like this: (file: and ftp: URLs are synonymous.)
The first part of the URL, before the colon, specifies the access
method. The part of the URL after the colon is interpreted specific to
the access method. In general, two slashes after the colon indicate a
machine name (machine:port is also valid).
When you are told to "check out this URL", what to do next depends on
your browser; please check the help for your particular browser. For
the line-mode browser at CERN, which you will quite possibly use first
via telnet, the command to try a URL is "GO URL" (substitute the
actual URL of course). In Lynx you just select the "GO" link on the
first page you see; in graphical browsers, there's usually an "Open
URL" option in the menus.
