HTML
What is HTML?
HTML is the "mother tongue" of your browser.
To make a long story short, HTML was invented in 1990 by a scientist called Tim Berners-Lee. The purpose was to make it easier for scientists at different universities to gain access to each other's research documents. The project became a bigger success than Tim Berners-Lee had ever imagined. By inventing HTML he laid the foundation for the web as we know it today.
HTML is a language, which makes it possible to present information (e.g. scientific research) on the Internet. What you see when you view a page on the Internet is your browser's interpretation of HTML. To see the HTML code of a page on the Internet, simply click "View" in the top menu of your browser and choose "Source".
What can I use HTML for?
If you want to make websites, there is no way around HTML. Even if you're using a program to create websites, such as Dreamweaver, a basic knowledge of HTML can make life a lot simpler and your website a lot better. The good news is that HTML is easy to learn and use. In just two lessons from now you will have learned how to make your first website.
HTML is used to make websites. It is as simple as that!
Okay, but what does H-T-M-L stand for?
HTML is an abbreviation of "HyperText Mark-up Language" - which is already more than you need to know at this stage. However, for the sake of good order, let us explain in greater detail.
• Hyper is the opposite of linear. In the good old days - when a mouse was something the cat chased - computer programs ran linearly: when the program had executed one action it went to the next line and after that, the next line and so on. But HTML is different - you can go wherever you want and whenever you want. For example, it is not necessary to visit MSN.com before you visit HTML.net.
• Text is self-explanatory.
• Mark-up is what you do with the text. You are marking up the text the same way you do in a text editing program with headings, bullets and bold text and so on.
• Language is what HTML is. It uses many English words.
In this tutorial you will learn so-called XHTML (Extensible Hyper Text Mark-up Language) which, in short, is a new and more well-structured way of writing HTML.

Convergence in Technology
Technological convergence is the tendency for different technological systems to evolve towards performing similar tasks.
Convergence can refer to previously separate technologies such as voice (and telephony features), data (and productivity applications), and video that now share resources and interact with each other, synergistically creating new efficiencies.
Today, we are surrounded by a multi-level convergent media world where all modes of communication and information are continually reforming to adapt to the enduring demands of technologies, "changing the way we create, consume, learn and interact with each other"
Convergence in this instance is defined as the interlinking of computing and other information technologies, media content, and communication networks that have arisen as the result of the evolution and popularization of the Internet as well as the activities, products and services that have emerged in the digital media space.
Many experts view this as simply being the tip of the iceberg, as all facets of institutional activity and social life such as business, government, art, journalism, health, and education are increasingly being carried out in these digital media spaces across a growing network of information and communication technology devices.
Also included in this topic is the basis of computer networks, wherein many different operating systems are able to communicate via different protocols. This could be a prelude to artificial intelligence networks on the Internet eventually leading to a powerful superintelligenc via a technological singularity.
The rise of digital communication in the late 20th century made it possible for media organizations (or individuals) to deliver text, audio, and video material over the same wired, wireless, or fiber-optic connections. At the same time, it inspired some media organizations to explore multimedia delivery of information. This digital convergence of news media, in particular, was called "Mediamorphosis"

XML Notes
XML was designed to transport and store data.
HTML was designed to display data.
What is XML?
• XML stands for EXtensible Markup Language
• XML is a markup language much like HTML
• XML was designed to carry data, not to display data
• XML tags are not predefined. You must define your own tags
• XML is designed to be self-descriptive
• XML is a W3C Recommendation
________________________________________
The Difference Between XML and HTML
XML is not a replacement for HTML.
XML and HTML were designed with different goals:
• XML was designed to transport and store data, with focus on what data is
• HTML was designed to display data, with focus on how data looks
HTML is about displaying information, while XML is about carrying information.

CorelDRAW
How to Use Corel Draw 12
Open your Corel Draw 12 program. The program's icon should be displayed on your computer's desktop screen. Double-click on the icon and the program will appear in a pop-up window automatically.
Study the tool bars that will appear both vertically and horizontally on the program's initial screen when it opens. These toolbars are considered your functional lifelines for this program. These tool bars have every essential item you will need to design anything you desire.
Choose the type of document style you want. You should see a drop box menu in the upper-left corner of the screen. Click on the downward arrow on the right side of the drop box menu to view the other possible document type options you can choose from. Once you click on a document type, the program will automatically change the document template to the document style you desire.
Decide on a background color. The background color you decide on will set the tone for your entire design creation. Click on the paint brush tool button on the left panel vertical menu. CMYK Color Palette will appear with a color wheel for you to choose the color you desire. When you select a color from the palette, that color will automatically be applied to the whole screen.
Choose the design elements you would like to implement to the top of the background. Your design elements will be listed along the top navigation menu in the effects folder, the horizontal menu, and the vertical toolbar. You can choose to upload photos on your hard drive to the program or you can create your own. If you choose to upload your picture, simply click on the "File" tab and select "Open". When your Windows Explorer dialog window opens, select the "Pictures" tab and choose the photo you would like to implement.
Add visual effects. Click on the "Effects" tab listed on the top navigation menu of the program. A list of visual effects will appear in a drop box menu below the tab. You can opt to change the size, color, and rotation of the object you've implemented. You can also opt to add animation and other flash effects to the photo if you desire.
Save your document. This is the most important part of your design. Click on the "File" tab and select the "Save As" option. When the Windows Explorer dialog window opens, choose a name for your design and type it in the data form provided at the bottom of the dialog window. Click on the "Save As" option to confirm the name and new file location of the document.

Basics of HTML
First HTML Assignment
Open Notepad to write your HTML code in. You will also need to open Netscape or Explorer to view the results. It doesnt matter whether you are connected to the Internet or not when you are working on these assignments. For the first part of the course, you will not be putting anything out on the web.
When I am coding HTML, I keep both Notepad and the browser I am using open so I can switch back and forth. Once you have opened the page in your browser, using the refresh key in the browser will show the latest saved version of the page you are working on.
This assignment should be passed in via email as an attachment. Here is what I want you to do:
• Save the web page as you are working on it with an .html or .htm extension.
• Just before you plan to send it to me, save it with a .txt extension.
• Send me the page with the .html or .htm extension and the page with the .txt extension as attachments to your email.
The reason for this is that depending on your email provider, sometimes the code gets changed in the .html or .htm version. Sending me the .txt version allows me to see the original code.
Steps:
• To do your assignment, you should first open Notepad. Do a very simple web page using the very basic HTML code so you can test something simple.
• Save it with an .html or .htm extension.
• Go to Netscape Communicator and select FILE/OPEN PAGE or go to Explorer and select FILE/OPEN. Depending on the version you are using, you may see something else but try to find something that allows you to open a page. You then need to select the file. Note that in Explorer you BROWSE.
• Look at the results of your code. If it worked the way you want it to you are on your way. If not you need to return to the HTML in Notepad and make some changes, save the page with the changes and refresh in the browser to see the new version.
To do this page effectively, I suggest that you look at my PowerPoint Presentations. Specifically look at the first two in the list. Presentations
I also suggest that you look at my sample web pages under HTML sample pages. Samples - look at the first 6 in the list
When you look at web pages, you can see the HTML code by going to VIEW in your browser and looking for SOURCE or PAGE SOURCE or something similiar. The key word here is source.
The web page you pass into me should have the following elements:
H1 for a header Another header in range H2 through H6 BR for break
P for a paragraph Bold Italics
CENTER UL LI
Background color Text color (set default for whole page) Alignment
Font size Text color for a phrase Underline
HREF used to get to a place on the same page NAME to show a entry point on the page Blockquote
Ordered List Unordered list Unordered list with a different bullet

Introduction of Flash
Introduction
The Macromedia Flash section of ReviseICT.co.uk has been created to help both students and teachers learn how to use Flash.
The Flashpaper resouces are the best to use if you are working online, or you can print out the .pdf versions to use as worksheets. Please let me know if you find these useful as more will then be added.
There are now six guidance pages - 'Introduction to Flash', 'Creating a game' (3 parts), 'Creating a drag-and-drop exercise' and 'Creating a Whack-Attack game'. Scroll down the page for more detials.
Starter
Introduction to Flash
Introductory resource - guiding users through the use of Flash as a basic design tool. Users using the drawing and fill tools to become familiar with the Flash interface.
The official Macromedia 'Learning Guides' are an excellent way to develop Flash skills. Macromedia is constantly adding additional support material online - make sure you visit their learning Flash materials.
Developing your first game - see what students have produced...
The 'creating a game tasks' (below) involve editing a pre-prepared Flash MX game. This game was originally created by Gary Rosenzweig for his marvelous book - Flash MX Actionscript for Fun & Games. This book is a great way to learn some of the more complex areas of Flash.
The following resources are based on this game file, which has been heavily edited in preparation for these carefully developed tasks.
Creating a game - part 1
Part 1: Adaptation and development of the game file. Involves locking and editing timeline frames, together with the creation of the 'ultimate game background' screen.
Creating a game - part 2
Part 2: Design and creation of the 'enemy'. Guides users to edit the game file exploring the use of symbols and identifiers. Many opportunities for extension work.
Creating a game - part 3

Drag and drop exercises in Flash
Explore some online examples of the benefits of drag-and-drop exercises. Then follow tutorials to create your own. Includes optional downloadable .fla that you might like to make use of.
Time: 30 minutes
From nothing to a game in 30 minutes!
With some basic knowledge of Flash, create your own game based on the classic 'Pong'. Design your own version that really smells quite good. Includes downloadable example and ideas to extend further.
Time: 30 minutes
Create your own Whack-Attack game
Create a Whack-Attack game following some detailed instructions. Find an image of an individual (yes, images of Mr Field are fine!) and then import it into Flash. You then customise the image and add your code.
Time: 45 minutes +
Overview
Macromedia Flash is an incredible tool, allowing professional designers and programmers to create rich content and applications. An amazing array of online experiences can be developed - from animations and graphical showcases to online games, high-end video and actual programs.
Aside from all this gobbledygook, Flash is simply a program that allows webpages to come alive.
Yet the one major problem with Macromedia Flash is that people, often quite rightly, think that is is difficult to learn. This page contains some ideas and resources to help people start learning about Flash. The best advice I can offer is that it is worth simply experimenting and exploring the possibilities yourself.
These resources have been created to help students at Neale-Wade Community College in March, Cambridgeshire, UK. Some related to the summer-school day in August 2004, others relate to the after school Advanced-ICT club.
