Multimedia and information

What is Multimedia?

Multimedia can have a many definitions these include:

Multimedia means that computer information can be represented through audio, video, and animation in addition to traditional media (i.e., text, graphics drawings, images).
A good general definition is:
Multimedia is the field concerned with the computer-controlled integration of text, graphics, drawings, still and moving images (Video), animation, audio, and any other media where every type of information can be represented, stored, transmitted and processed digitally.
A Multimedia Application is an Application which uses a collection of multiple media sources e.g. text, graphics, images, sound/audio, animation and/or video.

Hypermedia can be considered as one of the multimedia applications.

5 Components of Multimedia
Multimedia applications can include many types of media. The primary characteristic of a multimedia system is the use of more than one kind of media to deliver content and functionality. Web and desktop computing programs can both involve multimedia components. As well as different media items, a multimedia application will normally involve programming code and enhanced user interaction. Multimedia items generally fall into one of five main categories and use varied techniques for digital formatting.

Text

It may be an easy content type to forget when considering multimedia systems, but text content is by far the most common media type in computing applications. Most multimedia systems use a combination of text and other media to deliver functionality. Text in multimedia systems can express specific information, or it can act as reinforcement for information contained in other media items. This is a common practice in applications with accessibility requirements. For example, when Web pages include image elements, they can also include a short amount of text for the user's browser to include as an alternative, in case the digital image item is not available.


Images

Digital image files appear in many multimedia applications. Digital photographs can display application content or can alternatively form part of a user interface. Interactive elements, such as buttons, often use custom images created by the designers and developers involved in an application. Digital image files use a variety of formats and file extensions. Among the most common are JPEGs and PNGs. Both of these often appear on websites, as the formats allow developers to minimize on file size while maximizing on picture quality. Graphic design software programs such as Photoshop and Paint.NET allow developers to create complex visual effects with digital images.

Audio

Audio files and streams play a major role in some multimedia systems. Audio files appear as part of application content and also to aid interaction. When they appear within Web applications and sites, audio files sometimes need to be deployed using plug-in media players. Audio formats include MP3, WMA, Wave, MIDI and RealAudio. When developers include audio within a website, they will generally use a compressed format to minimize on download times. Web services can also stream audio, so that users can begin playback before the entire file is downloaded.

Video

Digital video appears in many multimedia applications, particularly on the Web. As with audio, websites can stream digital video to increase the speed and availability of playback. Common digital video formats include Flash, MPEG, AVI, WMV and QuickTime. Most digital video requires use of browser plug-ins to play within Web pages, but in many cases the user's browser will already have the required resources installed.

Animation

Animated components are common within both Web and desktop multimedia applications. Animations can also include interactive effects, allowing users to engage with the animation action using their mouse and keyboard. The most common tool for creating animations on the Web is Adobe Flash, which also facilitates desktop applications. Using Flash, developers can author FLV files, exporting them as SWF movies for deployment to users. Flash also uses ActionScript code to achieve animated and interactive effects.

Reflection on the "Visual media and Information"

    Reflection on the " Visual media and Information"         This topic so called Visual media and Information   must give an attention to understand by students because basically we are all visual learners. Therefore in order for us to learn better, visual media should be used effectively. We as teachers should also teach our students how to use visual media responsibly not only for entertainment but to use it productively. Also, attention span is very affected by visuals, thus, we as teachers should adjust our teaching methods to cope with the kind of learners we have today.              I've learned that there is three types of information sources do we have now adays which are; Primary Sources, Secondary Sources, and Tertiary Sources.Visual media can be used in any subject matter especially presenting texts through visuals such as data presented through graphs, tables and illustrations like pie chart and project these through power point p

Pre-Industrial Ages

Pre-Industrial Age (Before 1700s)          People discover fire, developed paper from plants, and forge weapon and tools with stone, bronze, copper, and iron. Papyrus In Egypt (2500BC)         First papyrus  was only used in  Egypt , but by about  1000 BC  people all over  West Asia  began buying papyrus from Egypt and using it, since it was much more convenient than  clay tablets (less breakable, and not as heavy!). People made papyrus in small sheets and then glued the sheets together to make big pieces. ( craft project ?) Cave Paintings (35,000BC) In  prehistoric art , the term “cave paintings” encompasses any  parietal art  which involves the application of  colour pigments  on the walls, floors or ceilings of ancient rock shelters. A monochrome cave paintings is a picture made with only one colour (usually black)-see, for instance, the monochrome images at  Chauvet Clay Tablets In Mesopotamia (2400BC)         In the Ancient Near East,  clay

Information Literacy    What is information Literacy ?         The term  "information literacy"  describes a set of abilities that enables an individual to acquire, evaluate, and use information. You can think of information literacy as having five components: identify, find, evaluate, apply, and acknowledge sources of information.          Information literacy  is a crucial skill in the pursuit of knowledge.  It involves recognizing when information is needed and being able to efficiently locate, accurately evaluate, effectively use, and clearly communicate information in various formats.  It refers to the ability to navigate the rapidly growing information environment, which encompasses an increasing number of information suppliers as well as the amount supplied, and includes bodies of professional literature, popular media, libraries, the Internet, and much more.  Increasingly, information is available in unfiltered formats, raising questions about its au
