WWW
The web encompasses a symmetric universal readership concept.
Anyone can publish anywhere on the web
without particularly sophisticated software and
and anyone can read anything on the web
with a single browser.
It is comprised of a few technologies or standards:
- html
- hypertext markup language
- URL
- Uniform Resource Locator
- http
- hypertext transfer protocol
Html is a simple standard language for describing
documents on the web. By using this language as
the base of web publishing -- all browsers and
other web tools can read everything on the web.
One of the key features of html is the specification
of URLs which are pointers to other web resources
-- in the simplest case other html documents.
URLs provide a standard way of addressing or
describing the location of where something is on the Internet.
http is an internet protocol which specifies who
client applications, for example browsers, can
access html documents and other objects anywhere
on the Internet.
httpd's are the server daemons that accept http requests
and respond by sending the specified objects to the requesting program.
Http allows a client to specify the object formats
(e.g. gif, jpeg, tiff, etc.)
it understands.
The httpd will then try to find the representation of an object
within the list provided by the requesting client.
