▫
▫
▫
▫
Perception media

8. Storage Media
• “Where is information stored”
• Refer to various physical means for storing
computer data, such as magnetic tapes,
magnetic disks, or digital optical disks (CDROM, CD, DVD)

9. Transmission Media
• “Which medium is used to transmit data”
• Refers to the physical means – cable of various
type (coaxial cable, twisted pair, fiber optics),

transmission of telecommunication signals.
• The difference between transmission media and
storage media is the capability of transferring
data continuously over networked computers.

31. Hyper Media
By
Altamas Ahammad

32. Interactive Multimedia
• When the user is given the option of
controlling the elements.
Hyper Media

A combination of hypertext, graphics,
audio, video, (linked elements) and
interactivity culminating in a complete,
non-linear computer-based experience.

33. Hypermedia
▫ Hypermedia is a way of organizing multimedia
information by linking media elements.
▫ Hypermedia has grown out of a fusion between
hypertext and multimedia.
▫ Hypertext was developed to provide a different
structure for basic text in computer systems :
 text is essentially sequential in nature, even though its
structure is hierarchical (chapters, sections, subsections,
paragraphs)
 hypertext was developed to permit more random access
between components of text documents, or between
documents, to allow a greater degree of flexibility and crossreferencing than a purely linear or sequential model would
allow.

34. Hypermedia
–
–
The structure of a hypermedia organizations is called a
hypermedia web, which consists of a number of
multimedia elements or nodes with links between them.
Links represent semantic relationships, thus when a link
exists between two nodes they must be related in some
fashion :
 a digital image linked to a textual description of it
 a slide-show linked to an audio commentary
–
Most widely used hypermedia tools are hypermedia
browsers, which let users view nodes and traverse links
between them, and markup languages, such as HTML,
which allow users to create hypermedia webs as structured
documents.

37. Linear VS Non-Linear
LINEAR
• A Multimedia Project is identified as Linear when:
– It is not interactive
– User have no control over the content that is being showed to
them.
• Example:
– A movie
– A non-interactive lecture / demo show

38. Linear VS Non-Linear
NON-LINEAR
•
•
A Multimedia Project is identified as Non-Linear when:
– It is interactive
– Users have control over the content that is being showed to them.
– Users are given navigational control
Example:
– Games
– Courseware
– Interactive CD
