ABSTRACT: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
signified, stored, communicated and handled digitally.
Multimedia can be recorded and played, displayed,
interacted with or accessed by information satisfied
processing devices, such as high-tech and automated devices,
but can also be part of a live presentation. Multimedia
devices are electronic media strategies used to store and
involvement multimedia content. Multimedia is notable from
diverse media in fine art; for model, by containing audio it
has a broader scope. In the early years of multimedia the
term "rich media" was identical with collaborating
multimedia, and "hypermedia" was an application of
multimedia. In this paper we discussed about the different
elements of multimedia along with its applications, features,
advantages and disadvantages so on.

1. INTRODUCTION
Multimedia has developed an unavoidable fragment of any
performance. It has originate a diversity of presentations right
from entertaining to education. The development of internet
has also enlarged the request for multimedia content.
Multimedia is the media that uses numerous forms of
information contented and information processing (e.g. text,
audio, graphics, animation, and video interactivity) to inform
or entertain the user. Multimedia also mentions to the use of
electronic media to store and knowledge multimedia content.
Multimedia is alike to traditional varied media in fine art, but
with a broader opportunity. The term “rich media” is equal for
interactive multimedia.
Multimedia elements
 Text
 Graphics
 Audio
 Video
 Animation
 Interactivity
Multimedia may be generally separated into linear and non-
linear groups. Direct active content developments without any
navigation control for the watcher such as a cinema
presentation. Non-linear content suggestions user interactivity
to control progress as used with a computer game or used in
self-paced computer created exercise. Non-linear content is
also known as hypermedia content. Multimedia presentations
can be live or noted. A recorded presentation may permit
interactivity via a steering system. A live multimedia
presentation may allow interactivity via interaction with the
presenter or performer.
2. ELEMENTS OF MULTIMEDIA
2.1. Text
Whether or not they have used a computer, most people are
familiar with text. Text is the foundation for word processing
programs and is still the fundamental information used in
many multimedia programs. In fact, many multimedia
applications are based on the conversion of a book to a
computerized form. This change gives the user instant access
to the text and lets him or her display pop-up windows, which
give meanings of certain words. Multimedia applications also
enable the user to instantly display information related to a
certain topic that is being viewed. Most powerfully, the
computerized form of a book allows the user to look up
information quickly (without referring to the index or table of
contents).The Windows operating environment gives the user
an almost infinite range of expressing text. As a multimedia
programmer, you can choose what font to display text in, how
big (or small) it should be, and what color it should be
displayed in .By displaying text in more than one format ,the
message a multimedia application is trying to portray can be
made more understandable. One type of application, which

Paper Title:-MULTIMEDIA AND ITS APPLICATIONS
ISSN:-2349-3585 |www.ijrdt.org
272
many people use every day, is the Windows Help Engine. This
application is a text-based information viewer that makes
accessing information related to a certain topic easy.
2.2 Audio Sound:
The combination of audio sound into a multimedia application
can offer the user with information not likely finished any
other technique of announcement .Some types of information
can't be taken efficiently without using sound. It is closely
impossible, for instance, to provide a precise word-based
explanation of the bear of a heart or the sound of the ocean.
Audio sound can also strengthen the users considerate of
information obtainable in another type of media. For example,
a description might define what is being seen in an animation
clip. This can enhance the understanding of what the
application is all about and lead to better comprehension.
Experts in learning have found that presenting information
using more than one sense aids in later retaining of the
information. Most importantly, it can also make the
information more interesting to the user. Audio sound is
available in several different formats. Today, maybe the
greatest collective type of audio is red book audio. This is the
normal prerequisite used to mention to customer audio
compacted discs. It is an worldwide standard and is formally
recognized as IEC 908.This description is called red book
audio meanwhile of the color of the cover of the publication
that defines its formats. Red book audio sound can also be
used in multimedia applications, and it forms the basis of the
highest quality sound available. Another audio sound format is
the Windows wave file, which can be played only on PCs
running the Windows operating environment. A wave file
contains the actual digital data used to play back the sound as
well as a header that provides supplementary information
about the determination and playback rate. Wave files can
store any sort of sound that can be verified by a microphone.
The last type of audio sound that may be used is known as the
Musical Instrument Digital Interface or MIDI for short. The
MIDI format is actually a specification invented by musical
instrument manufacturers. Rather than being a digitized form
of the sound, the MIDI specification is actually a set of
messages that describes what musical note is being played.
The MIDI requirement cannot accumulation whatever but in
the form of musical notes. MIDI music can be shaped with a
sequencer.
2.3. Static Graphics images:
When you imagine graphics images you believably think of
"still" images-that is, images such as those in a photograph or
drawing. There is no occurrence in these kind of picture. Still
graphics images are an all important portion of multimedia
because humans are modality adjusted. As the old Chinese
saying goes, "A picture is worth a thousand words."Windows
is also a sense modality environment. This kind displaying
graphics images easier than it would be in a DOS-based
environment. Static graphics images have a certain concept of
formats and can be created in a number of various ways. Just
as you can see an limitless number of photographs or pictures,
the types of static graphics images that you can include in a
multimedia application are almost unlimited.
2.4. Animation
Animation mention to moving graphics images. The
happening of somebody giving CPR makes it much easier to
learn internal organ revitalization, rather than just screening a
static picture. Just as a static graphics image is a all-powerful
form of human action, such is the case with animation.
Animation is particularly useful for enlarge concepts that
affect movement. Such thought as playing a guitar or hitting a
golf ball are hard to exemplify using a single photograph, or
even a ordination of photographs ,and equal more difficult to
explicate using text. Animation form it easier to portray these
characteristic of your multimedia application.
2.5. Full-Motion Video
Full-motion video, such as the images depicted in a television,
can add even more than to a multimedia application. Although
full-motion video may sound similar an perfect way to add a
powerful message to a multimedia application, it is nowhere
near the quality you would anticipate after watching
television. Full-motion video is still in its occurrence stages on
PCs, and it is constricted in resolution and size. Even with
precocious methods of data compression, full-motion video
can suck up hard disk space faster than waterfalls when
poured out of a bucket.
3. USES AND APPLICATIONS OF MULTIMEDIA:
3.1 Multimedia in Education:

Paper Title:-MULTIMEDIA AND ITS APPLICATIONS
ISSN:-2349-3585 |www.ijrdt.org
273
Multimedia combining respective media in a one evidently it
has more beginning of information. So it is extended used in
the field of education and training. Even in conventional
method we use audio visual for imparting education, where
charts, models etc. were used. Now days the classroom
demand is not limited to that accepted method instead it needs
audio and visual media. The multimedia incorporate all of
them in one system. For the use of multimedia as an education
assistance the PC integrated a high quality display. This all has
advance the improvement of a wide scope of computer based
training. The software package named computer aided
direction is accessible that supply a friendly interactive acting
of learning.
3.2Multimedia in Training:
There diverse systems and intelligent tutoring systems
accessible to train the students in numerous areas opening
from the mathematics of a original abrupt to a difficult
surgical process for a medical student. As there sufficient
audio clips added these tutorials and an action can be seen
from all orientation and repetition so evidently as far as
practical skills is obsessed it gives a lot of far that. These
packages are just like expert systems and are fully equipped
with decision making utility-grade to impact training after
judging the competence of a student in the several field. These
tutorials incorporate enough number of videos sequences
clarify.
3.3 Science and Technology:
Multimedia had a broad application in the field of science and
technology. Whether it is an industry or the case of sciences
all are benefited by its use. The multimedia application and
beneficial for researchers as well as over the world. The
multimedia system is competent of transferring audio, and
clips in addition to the regular text. It is even capable of
sending message and formatted multimedia documents. At the
same time the multimedia also helps in live which is a live
interaction through audio messages and it is only possible with
the multimedia. It reduces the time and cost can be arranged at
any moment even in emergencies. It is adequate for
communication and meetings. At the same time the
multimedia is sufficiency useful services based on images.
3.4 Multimedia in Business:
The business application of multimedia includes, product
demos, instant messaging. One the excellent applications are
voice and live conferencing. A multimedia can make a
audience come live. It is widely used in programs. Such a
program can be used by a mechanic and peoples. There are a
number of easy to use authoring programs and tools that can
even let workers to create their own program. There are a
number of applications available that slow to run more
smoothly and effectively.
3.5Multimedia in Games:
One of the most exciting applications of multimedia is games.
Now days the live internet pay to play gaming with multiple
players has become popular. Actually the first application of
multimedia system was in the field of entertainment and that
too in the video game industry. The integrated audio and video
effects make various types of games more entertaining.
Generally most of the video games need joystick play.
3.6 Creative industries:
Creative industries use multimedia for a variety of purposes
ranging from fine arts, to entertainment, to commercial art, to
journalism, to media and software services provided for any of
the industries listed below. An individual multimedia designer
may cover the spectrum throughout their career. Request for
their skills range from technical, to analytical, to creative.
3.7 Language communication:
With the spread and development of the English language
around the world, it has become an important way of
communicating between different people and cultures.
Multimedia Technology creates a platform where language
can be taught. The traditional form of teaching English as a
Second Language (ESL) in classrooms have drastically
changed with the prevalence of technology, making easier for
students to obtain language learning skills. Multimedia
motivates students to learn more languages through audio,
visual and animation support. It also helps create English
contexts since an important aspect of learning a language is
developing their grammar, vocabulary and knowledge of
pragmatics and genres. In addition, cultural connections in
terms of forms, contexts, meanings and ideologies have to be
constructed. By improving thought patterns, multimedia
develops students’ communicative competence by improving

274
their capacity to understand the language. One of the studies,
carried out by Izquierdo, Simard and Pulido, presented the
correlation between “Multimedia Instruction (MI) and
learners’ second language (L2)” and its effects on learning
behavior. Their findings based on Gardner’s theory of the
“socio-educational model of learner motivation and attitudes”,
the study shows that there is easier access to language learning
materials as well as increased motivation with MI along with
the use of Computer-Assisted Language Learning.
3.8 Medicine:
In medicine, doctors can get trained by looking at a virtual
surgery or they can simulate how the human body is affected
by diseases spread by viruses and bacteria and then develop
techniques to prevent it. Multimedia applications such as
virtual surgeries also help doctors to get practical training.
4. FEATURES OF MULTIMEDIA:
4.1 Photo gallery:
Show your photos arranged in a nice-looking grid format.
Example:
4.2 Slideshows:
Combine your pictures with music and animate them in a
slideshow.
Example:
4.3 Audio player:

data, initially established for storing digital audio. The CD,
accessible on the market since late 1982, remains the typical
playback medium for marketable audio recordings to the
current day, however it has lost ground in recent years to MP3
players. An audio CD consists of one or more stereo tracks
stored using 16-bit PCM coding at a selection rate of 44.1
kHz. Standard CDs have a diameter of 120 mm and can taking
hold about 80 minutes of audio. There are also 80 mm discs,
sometimes used for CD singles, which hold approximately 20
minutes of audio. The technology was later adapted for use as
a data storage device, known as a CD-ROM, and to include
record once and re-writable media (CD-R and CD-RW
respectively). CD-ROMs and CD-Rs stay widely used
practical application in the computer industry as of 2007. The
CD and its extensions have been extremely successful: in
2004, the worldwide sales of CD audio, CD-ROM, and CD-R
reached about 30 billion discs. By 2007, 200 billion CDs had
been sold global.
6.2 DVD
DVD (also known as “Digital Versatile Disc” or “Digital
Video Disc”) is a best-selling optical disc storage media
format. Its primary uses are video and data storage. Most
DVDs are of the identical dimensions as compact discs (CDs)
but store more than 6 times the data. Variant of the term DVD
often depict the way data is stored on the discs: DVD-ROM
has data which can only be read and not written, DVD-R can
be written once and then functions as a DVD-ROM, and
DVD-RAM or DVD-RW holds data that can be re-written
multiple times. DVD-Video and DVD-Audio discs
respectively mention to decently formatted and organized
video and audio contented. Another types of DVD discs,
consider those with video content, may be referred to as DVD-
Data discs. The term “DVD” is commonly misused to refer to
high density optical disc formats in general, such as Blu-ray
and HD DVD.“DVD” was originally used as an initialism for
the unofficial term “digital video disc”. It was reported in
1995, at the time of the specification finalization, that the
letters officially stood for “digital versatile disc” (due to non-
video applications), however, the text of the press release
announcing the specification finalization only refers to the
technology as “DVD”, making no mention of what (if
anything) the letters stood for. Usage in the present day varies,
with “DVD”, “Digital Video Disc”, and “Digital Versatile
Disc” all being common.
6.3 About Flash Drives
A USB flash drive is a data storage device that includes flash
memory with an integrated Universal Serial Bus (USB)
interface. USB flash drives are typically removable and
rewritable, and physically much smaller than a floppy disk.
Most weigh less than 30 g. As of January 2012 drives of 1
terabytes (TB) are available. and storage capacities as large as
2 terabytes are planned, with steady improvements in size and
price per capacity expected. Some allow up to 100,000
write/erase cycles (depending on the exact type of memory
chip used) and 10 years shelf storage time. USB flash drives
are often used for the same purposes for which floppy disks or
CD-ROMs were used. They are smaller, faster, have
thousands of times more capacity, and are more durable and
reliable because they have no moving parts. Until
approximately 2005, most desktop and laptop computers were
supplied with floppy disk drives, but floppy disk drives have
been abandoned in favor of USB ports. USB flash drives use
the USB mass storage standard, supported natively by modern
operating systems such as Linux, Mac OS X, Windows, and
other Unix-like systems, as well as many BIOS boot ROMs.
USB drives with USB 2.0 support can store more data and
transfer faster than much larger optical disc drives like CD-
RW or DVD-RW drives and can be read by many other
systems such as the Xbox 360, PlayStation 3, DVD players
and in some upcoming mobile smart phones.
6.4 About Internet
The Internet is a global system of interconnected computer
networks that use the standard Internet protocol suite (TCP/IP)
to serve billions of users worldwide. It is a network of
networks that consists of millions of private, public, academic,
business, and government networks, of local to global scope,
that are linked by a broad array of electronic, wireless and
optical networking technologies. The Internet carries an
extensive range of information resources and services, such as
the inter-linked hypertext documents of the World Wide Web
(WWW) and the infrastructure to support email.

7. ADVANTAGES OF MULTIMEDIA
Creativity:
It brings more life to discussions.
Variety:
It caters all types of learners.
Cost-effective:
Multimedia mostly requires only a one-time purchase of
devices and software, which can be used unlimited times
thereafter.
Evaluation:
It offers ideal learning assessment tools which are also
entertaining for the students.
Realistic Approach:
It provides approaches which make learning more realistic.
Wide Variety of Support:
Multiple media formats are available for use, with different
models being able to create multimedia.
Trendy:
The current trend of culture leans toward technology, and a
great number of resources are being made available for
different media formats.
8. DISADVANTAGES OF MULTIMEDIA
Accessibility:
Multimedia definite quantity electricity to be operated, which
may not be accessible in some rural areas or may not be
systematically acquirable due to deficit and intermission.
Distracting:
Multimedia may take away the focusing from the lesson due
to its attention-grabbing formats.
Costly:
Production of multimedia is more costly than others because it
is made up of more than one medium.. Production of
multimedia requires an electronic device, which may be
relatively expensive. Multimedia requires electricity to run,
which adds to the cost of its use.
Time Consuming:
Creating multimedia requires more time.
Requires Mastery :
Multimedia requires consistent and long practice to master,
which may take a lot of time and energy from the user.
Limited Support/Compatibility:
There is a wide variety of gadget models which arouses
incompatibilities of media formats.
Fragile:
The device used for multimedia must be used with attention;
vulnerability to moisture or other elements could cause costly,
reparable damage which would require another purchase of a
device.
9. CONCLUSION:
There are two ways we can think through with multimedia.
The first is to think about multimedia through definitions,
histories, examples, and theoretical problems. The second way
is to use multimedia to deliberation and to communicate
thought. The domain study of multimedia system is a
"thinking-about" that is typically communicated through
academic locale like textbooks, articles, and lectures.
"Thinking-with" is the occupation of multimedia that has its
own traditions of linguistic unit, forms of organization, tools,
and outcomes. To think-with multimedia is to use multimedia
to research ideas and to communicate them. In a field like
multimedia, where what we think about is so new, it is
important to think-with. Scholars of multimedia should take
seriously the challenge of creating multimedia as a way of
thinking about multimedia and attempt to create exemplary
works of multimedia in the cognitive content of the
humanities.
