2. Multimedia
Multimedia is a form of communication that uses a
combination of different content forms such
as text, audio, images, animations, or video into a single
interactive presentation, in contrast to traditional mass
media, such as printed material or audio recordings, which
features little to no interaction between users. Popular
examples of multimedia include video podcasts, audio
slideshows and animated videos. Multimedia also contains
the principles and application of effective interactive
communication such as the building blocks of software,
hardware, and other technologies. The five main building
blocks of multimedia are text, image, audio, video, and
animation.

4. Text

5. Text
 Inis a work literary theory, a text is any object that can be
"read", whether this object of literature, a street sign, an
arrangement of buildings on a city block, or styles of clothing.
It is a coherent set of signs that transmits some kind of
informative message.[1] This set f signs is considered in terms
of the informative message's content, rather than in terms of
its physical form or the medium in which it is represented.
 Within the field of literary criticism, "text" also refers to the
original information content of a particular piece of writing;
that is, the "text" of a work is that primal symbolic
arrangement of letters as originally composed, apart from
later alterations, deterioration, commentary,
translations, paratext, etc. Therefore, when literary criticism
is concerned with the determination of a "text", it is
concerned with the distinguishing of the original information
content from whatever has been added to or subtracted from
that content as it appears in a given textual document (that is,
a physical representation of text).

6. Audio

7. Audio
 In physics, sound is a vibration that propagates as
an acoustic wave, through a transmission medium such as a
gas, liquid or solid. In human physiology and psychology,
sound is the reception of such waves and their perception by
the brain.[1] Only acoustic waves that have frequencies lying
between about 20 Hz and 20 kHz, the audio frequency range,
elicit an auditory percept in humans. In air at atmospheric
pressure, these represent sound waves with wavelengths of
17 meters (56 ft) to 1.7 centimeters (0.67 in). Sound waves
above 20 kHz are known as ultrasound and are not audible to
humans. Sound waves below 20 Hz are known as infrasound.
Different animal species have varying hearing ranges.

8. Images

9. images
 An image is a visual representation of something. An
image can be a two-dimensional (2D) representation, such
as a drawing, painting, or photograph, or a three-
dimensional (3D) object, such as a carving or sculpture.
An image may be displayed through other media,
including projection on a surface, activation of electronic
signals, or digital displays. Two-dimensional images can be
still or animated. Still images can usually be reproduced
through mechanical means, such as
photography, printmaking or photocopying. In some
cases, three-dimensional images may also be animated
(capable of passive or active motion).
 The term has a technical meaning in some fields. In the
context of signal processing, an image is a distributed
amplitude of color(s).[1] In optics, the term "image" may
refer specifically to a 2D image.

10. A volatile image is one that exists or is perceived only for
a short period of time. This may be a reflection of an
object by a mirror, a projection of a camera obscura, or a
scene displayed on a cathode-ray tube. A fixed image,
also called a hard copy, is one that has been recorded on
a material object, such
as paper or textile by photography or any other digital
process.
A mental image exists in an individual's mind, as
something one remembers or imagines. The subject of
an image need not be real; it may be an abstract
concept, such as a graph, function, or imaginary entity.
For an image to be understood, however, there must be a
way of conveying that mental image through the words
or visual productions of the individual subject.

11. Animation

12. Animation is the method by which still images are
manipulated to create moving images. In traditional
animation, images are drawn or painted by hand on
transparent celluloid sheets to be photographed and
exhibited on film. Today, many animations are computer
animations made with computer-generated
imagery (CGI). Stop motion animation, in
particular claymation, has continued to exist alongside these
other forms.
Animation is contrasted with live-action film, although the
two do not exist in isolation. Many moviemakers have
produced films that are a hybrid of the two. As CGI
increasingly approximates photographic imagery,
filmmakers can easily composite 3D animations into their
film rather than using practical effects for showy visual
effects (VFX).

13. Video

14. Video is an electronic medium for the
recording, copying, playback, broadcasting, and
display of moving visual media.[1] Video was first
developed for mechanical television systems, which
were quickly replaced by cathode-ray tube (CRT)
systems which, in turn, were replaced by flat panel
displays of several types.
Video systems vary in display resolution, aspect
ratio, refresh rate, color capabilities and other
qualities. Analog and digital variants exist and can
be carried on a variety of media, including radio
broadcasts, magnetic tape, optical discs, computer
files, and network streaming.
