To publish on the web, you
have to understand the basis concepts that make up the parts of the web.
Today, you learned three major concepts. First, you learned about a few of the
more useful features of the web for publishing information. Second, you learned
about web browsers and servers and how they intract to deliver web pages.
Third, you learned about what a URL is and why it’s Important to web browsing
and publishing.
WORKSHOP
Each lesson in this book contains a workshop to help you
review the topics you learned the first section of this workshop listed some
common questions about the web. Next, you’ll answer some questions that I’ll
ask you about the web. The answers to the quiz appear in the next section. At
the end of each lesson, you’ll find some exercises that will help you retain
the information you learned about the web.
QUESTION&ANSWER (Q&A)
Q
who runs the web? Who controls all these protocols? Who’s in
charge of all this?
A
No single entity owns
or controls the world wide web. Given the enormous number of independent sites
that supply information to the web, for any single organization to set rules or
guidelines would be impossible. Two groups of organizations, however, have a
great influence over the look and feel and direction of the web itself.
The first is the
world wide web consortium (w3c), based at Massachusetts institute of
technology in the united states and INTRIA in Europe. The w3c is made up of individuals and
organizations interested in supporting and defining the languages and protocols
that make up the web (HTTP, HTML, XHTML, and so on),. It also provides
products(browsers, servers, and so on) that are freely available to anyone who
wants to use them. The w3 consortium is the closest anyone gets to setting the
standards for and enforcing rules about the world wide web. You can visit the
consortium’s home page at http://www.w3.org/.
The second group of organizations that influences the web is
the browser developers themselves, most no ability Microsoft and the Mozilla
foundation. The competition to be the most popular and technically advanced
browser on the web can be fierce. Although both organizations claim to support
and adhere to the guidelines proposed by the w3C, both also include their own
new features in new versions of their software_ features that sometimes
conflict with each other and with the work the w3C is doing.
Things still change pretty rapidly on the web, although not
as rapidly as they did in the height of the so-called browser wars. The popular
browsers are finally converging to support many of the standards defined by the
W3C, so writing to those standards will work most of the time. I’ll talk about
the exceptions throughout this book.
Q
I’ve heard that the
web changes so fast that it’s almost impossible to stay current. Is this book doomed to be out of date the day it’s
published?
A
Although it’s true
that things do change on the web, the vast majority of the information in this
book will serve you well far into the future. HTML and XHTML are as stable now
as they have ever been, and once you learn the core technologies of HTML, CSS,
and JavaScript, you can add on other things at your leisure.
QUICK
1.
What’s a URL?
2.
What’s required to publish documents on the web?
QUIZ ANSWERS
1.
A URL , or uniform resource locator, is an
address that points to a specific document or bit of information on the
internet.
2.
You need access to a web server. Web servers,
which are programs that serve up documents over the web, reply to web browser
requests for files and send the requested pages to many different types of
browsers. They also manage form input and handle database integration.
EXERCISES
1.
Try navigating to each of the different types of
URLs mentioned today (http:, ftp:, and news:), some links you might want to try
are http://www.tywepub.com, ftp://ftp.cdrom.com, and news:comp.
infosystems.www.
2.
Download a different browser than the one you
ordinarily use and try it out for a while. If you’re using internet explorer,
try out Mozilla, nets cape, opera, or even a command-line browser such as lynx
or links. To really see how things have changed and how some users who don’t
upgrade their browser experience the web, download an old browser from
http://browsers .evolt.org/ and try it out.
