A URL is an
address for a WWW site. Just as every
home has a number, street, city, state address, every WWW page has a
URL. The URL is what you use to locate
a particular site when you're on the Web.
The URL provides information that tells your computer (client) exactly
where to go (server).

|
|
The format is:
|
|
|
|
protocol://server
& domain/directory/file & extension.
So, the URL that's on this slide tells the client to go to the
med-libwww server at the boston university (which is an educational
institution) domain. The directory is
called "library", and within that directory, is a page or file
called home. The html tag indicates
that this file was written in the html language (as opposed to a gif
(graphics) or other kind of file.)

At this point,
does anyone have any questions or comments about the history and background
of the Internet & WWW?
