Grade Nine Information and Design Technology
FrontPage
HTML
HTML is the language of
web pages.
In order to truly
understand HTML, you need to know a little about browsers,
and in order to understand browsers, you really need to know
a little about how the web works.
The World Wide Web is a
huge collection of computers which are linked together in a
network.
When I say that they're
linked together, I don't necessarily mean physically. What I
mean is that they can communicate with each other. They do
this by sending data to each other.
Data is INFORMATION.
That's all it is. Don't let the technical words scare you
off. I won't be using too many.
Data, or information,
is stored on every computer on the internet, and takes many
forms. Spreadsheets are a form of data, as are Word
documents, images, sound bites, and web pages.
Now, you may have
noticed that on your computer, when you want to open a
document, you sometimes need to use a specific program to do
that. If you want to look at a JPEG image, you open it in
Photoshop. If you want to view a file that ends in .DOC,
you'll use Microsoft Word.
The reason for that is
that inside of a file, things are written very strangely.
Files are usually encoded, and depending on the type of
file, they use different codes. The application you open a
file with, needs to understand the code it was written with.
If I want to communicate with a German, I find someone who
can speak German to translate for me. If I asked someone who
knew Italian, but had no knowledge of German, I would be out
of luck. The German would speak and the Italian translator
would just shrug.
Web pages are encoded
in their own special way too. The encoding process isn't
difficult, and is usually done by hand. The way pages are
encoded is with a MARK-UP language we call HTML. The letters
stand for HyperText
Mark-Up Language.
Remember that web pages are usually used as a means of
conveying data, or information. The data is your message.
This is the meat of the HTML document. Text and content are
most important.
Once you have created a
web page, you store it on a certain type of computer called
a web server. Web servers are computers which are attached
to the Internet, and do basically two things. A web server
stores information documents and sends those documents to
any other computer which requests them.
Here's what really
happens when you surf the web...
you connect to the
Internet with a special type of computer program known as a
browser. The first thing the browser wants to know is where
to go. You type in a url. URL stands for
Uniform Resource
Locator
A url is an address.
This address tells the browser exactly where to find the
page you're looking for.
This is an example of a
URL:
http://www.senri.ed.jp
What happens next is
that your browser writes a quick message to the computer at
that address requesting the page you want. In less than a
second, the request has been delivered. The computer which
has received the request (The Web Server, remember?) grabs
the data for the requested page, and shoots it back to the
requesting computer.
"Hey, send me such and
such page"
"okay, Here ya go!"
So now, you have the
data for that web page on your computer, but it's slightly
encrypted, remember?
The browser takes all
that raw data, and translates it. Then displays it on your
screen. what the browser sees is raw data, which might look
like this:
<img src="http://www.senri.ed.jp/departments/OISTech/OISDT/gr9tech/Logo.jpg">
But what you see is the
browsers interpretation of that data (such as the image
below).
You see, HTML is simply
a way for you to tell your visitor's browser how you want it
to display your data.
OK... during this part
of the course, you will get a chance to learn a little
something about what makes the internet and the world wide
web function. If you were in OIS in grade 8 last year you
should remember how to write some HTML code, this will be
very helpful during this course.
We will be working on
what the IBO calls an MYP Interdisciplinary Project (a long
name for two subjects working together). We will be working
with Mr Shiffman and Mr Sommer in English. This
trimester you will be studying
This
Boy's Life,
the ancient Greek tragedy
Antigone or some other important work. This study will require
you to complete a number of different tasks. In IDT you
will create a website to present the work you do in English.
But, don't worry if you
know absolutely nothing about web pages or HTML, this year
you will be making your website using a piece of software
called Microsoft FrontPage 2003. This is an easy to use
webpage creator. It allows you to write in code if you want
or you can build a page just like using MS Word. The links
on the
Gr 9 Computer Technology page
for will show you everything you'll need to know to make
your own web pages using FrontPage 2003 and HTML code.
Alternatively, you can use Weebly.com, an online web site
builder. |
