Multimedia authoring 
Development of any application that uses a range of media types to present information
Media types incorporated into multimedia applications
Sound
Video
Animation
Graphics
Text
Hypertext 
Use of text to provide links to related content
Hypermedia 
Use of multimedia elements to provide links to related content
Multimedia authoring applications 
Contain predefined elements to support development of packages
Provide WYSIWYG (what you see is what you get) environment to support visual development using drag and drop tools
Do not require end user to have underlying knowledge of programming language
Multimedia authoring applications 
Automatically generate underlying code as new content is added
Provide features like template provision, content management, form tools, hyperlinks and hotspots, and wizards
HTML (Hypertext Markup Language) 
Text-based language used to describe layout of content displayed using web browser applications
HTML 
Uses tags to describe page content
Has a basic structure with doctype, head, and body sections
Metadata 
Data which describes other data. In an HTML document, metadata is defined inside the <head></head> tags
Fallback text 
Error message in the event that a file cannot be played by the browser
HTML tags for graphics, video, and audio
<img>
<audio>
</audio>
<video>
</video>
HTML tags for tables and lists 
<table>
</table>
<th>
</th>
<td>
</td>
<ol>
</ol>
<ul>
</ul>
<li>
</li>
Developers will manage around with update patches of the application

How it affects display
Displays an ordered list. In this case the ol tag has the '1' type for style) assigned to it so items in the list will be numbered.
How it affects display
Displays an unordered list. In this case the <ul> tag has a disc style assigned to it so the list will be displayed as a bulleted list of names using solid bullet points (disc).
HTML tags for commenting and adding hyperlinks 
<! -- Any comments to help with the understanding of HTML code can be inside this tag -->
<a href="http://www.mypage.com">Click here</a>
It is easy to read short extracts of HTML code and understand its placement of content on a web page. It is important that you are familiar with all tags and can identify errors in their use. You should also be familiar with the structure of an HTML document.
Advantages of using HTML to create a multimedia solution
Most developers are familiar with HTML
It is supported by all browsers
It is free and no additional software is needed
Content management
Disadvantages of using HTML to create a multimedia solution
Updating links can be difficult if content is not managed effectively
Can only create static pages; if a dynamic page is required then additional script (e.g. Java script) is needed
Many lines of script are needed for even the most basic of pages
Static web pages 
Pages that are presented to the user in the form that they were created, they tend to end with the extension .htm or .html
Dynamic web pages 
Pages where the presentation can be changed by a user's interactions with the application; they tend to end with the extensions.php. asp or jsp
CSS (cascading style sheets) 
A language used to describe the style of an HTML document; it describes how specified elements will be displayed
Sequencing 
All lines of code run one after another and all lines of code are executed. The order of execution of the script never changes.
Selection 
Used in instances where only some lines of code need to be executed and only if a certain condition is met. If the condition is not met, the code is not executed.
Repetition 
Causes lines of code to be executed again and again; either a specific number of times, until a condition is met or while a condition is met
Event-driven programming 
Where events such as the user's interaction with an application element can determine how the application is presented to the end user
