Week 27 - Internet - Hypertext, HTTP, HTML, Link
HTTP & HTML:
HTTP is short for HYPER TEXT TRANSFER PROTOCAL.
HTML is short for HYPER TEXT MARKUP LANGUAGE.
Once again the computer geeks have tried to make the simple seem complicated. This time they did a really good job. But it's not
that hard. Remember that HYPERTEXT? When you clik on HYPERTEXT you are activating it to TRANSFER data using the special
PROTOCAL (or procedure) to link the hypertext to it's destination--thus HYPER TEXT TRANSFER PROTOCAL OR HTTP.
You will almost always see 'HTTP' in URLs such as 'http://www.whatever.com'. Notice at the top of this screen on your WEB
BROWSER that it says 'http://www.schoollife.net/schools/stphilipneri....'.
This means that the website is accessed (and has been written) through the PROTOCOL which uses HYPERTEXT. HTML (HYPER
TEXT MARKUP LANGUAGE) is the computer language (consisting of 'hidden codes:) which is used to actually write a website. In
the old days (like 2 or 3 years ago) a webmaster needed to learn this somewhat complicated
computer 'language' in order to make a website work. In HTML this page of our website would look like:
-HTML-HEAD-TITLE>Continued From Previous Page--TITLE>
Not exactly like that because if I had entered perfect HTML then the information would have shown up as it does on the webpage.
Anyway...
It is not necessry now a days to know HTML in order to create a website. Literally anyone who can type can create and publish a
webpage because sofware is available usually free) which makes this almost as easy as word processing. Netscape Page
Composer is one of many of these.
LINK
A colored word or words (called hypertext) on a webpage that LINKS you with another page or site. You know when you've hit a
LINK because the pointer (or curser) turns into a hand. If you click your mouse, you will leave the page you are currently on and
move to another page to which the page was LINKED. To return to the previous page, you can click on the 'Back' button at the top
left corner of the WEB BROWSER.
You would not be on this page of our website if you had not clicked on the LINK that is titled 'The Word...', either on our homepage
or at the top of each page. In fact, almost every page of our website is headed with the Viking and the list of our LINKS.
HYPERTEXT
When surfing the web there are often all sorts of distractions--advertisements, 'free' offers, blinking images, false error messages,
annoying 'pop-up' windows, etc. It is sometimes difficult for new users to understand what information is important in a website and
what is just fluff. That's why it is important to know about and be able to find the website hypertext amid all of this other stuff.
Hypertext is colored text which, when clicked on, brings the user to another page (or 'screen'). Hypertext is sometimes called
'links' because that's what it does--it links one page to another. Not only is hypertext colored it is also often underlined (you can set
up your browser to always underline hypertext). You'll know when you've landed on hypertext because your mouse pointer will turn
into a hand whenever you pass it over hypertext.
Internet graphics are becoming increasingly sophisticated which allows hypertext to be hidden in images. So how do you know
where the hypertext is? It's really quite simple:
Hypertext may be
1. colored text
2. underlined colored text
3. a graphic image BUT
IF YOUR MOUSE POINTER TURNS INTO A HAND then you know that you have hit a hypertext link. If you click on hypertext you will
be directed to another page.
It's easy to remember the term because we all know the word HYPERACTIVE and understand it to mean EXTRA ACTIVE which is
exactly what hypertext is--EXTRA ACTIVE TEXT which allows us to move around the Internet. Or 'extra active' graphics which do
to same.
