1) Computer graphics
Computer graphics are graphics created using computers and, more generally, the
representation and manipulation of image data by a computer with help from specialized
software and hardware.
The development of computer graphics has made computers easier to interact with, and better for
understanding and interpreting many types of data. Developments in computer graphics have had
a profound impact on many types of media and have revolutionized animation, movies and the
video game industry.
The term computer graphics has been used in a broad sense to describe "almost everything on
computers that is not text or sound".[1] Typically, the term computer graphics refers to several
different things:



the representation and manipulation of image data by a computer
the various technologies used to create and manipulate images
the sub-field of computer science which studies methods for digitally synthesizing and
manipulating visual content, see study of computer graphics
Computer graphics is widespread today. Computer imagery is found on television, in
newspapers, for example in weather reports, or for example in all kinds of medical investigation
and surgical procedures. A well-constructed graph can present complex statistics in a form that is
easier to understand and interpret. In the media "such graphs are used to illustrate papers, reports,
thesis", and other presentation material.[2]
Many powerful tools have been developed to visualize data. Computer generated imagery can be
categorized into several different types: 2D, 3D, and animated graphics. As technology has
improved, 3D computer graphics have become more common, but 2D computer graphics are still
widely used. Computer graphics has emerged as a sub-field of computer science which studies
methods for digitally synthesizing and manipulating visual content. Over the past decade, other
specialized fields have been developed like information visualization, and scientific visualization
more concerned with "the visualization of three dimensional phenomena (architectural,
meteorological, medical, biological, etc.), where the emphasis is on realistic renderings of
volumes, surfaces, illumination sources, and so forth, perhaps with a dynamic (time)
component".[3]
2) Graphic design
Graphic symbols are often functionalist and anonymous,[1] as these pictographs from the US
National Park Service illustrate.
Graphic design is a creative process—most often involving a client and a designer and usually
completed in conjunction with producers of form (i.e., printers, signmakers, etc.)—undertaken in
order to convey a specific message (or messages) to a targeted audience. The term "graphic
design" can also refer to a number of artistic and professional disciplines that focus on visual
communication and presentation. The field as a whole is also often referred to as Visual
Communication or Communication Design. Various methods are used to create and combine
words, symbols, and images to create a visual representation of ideas and messages. A graphic
designer may use a combination of typography, visual arts and page layout techniques to produce
the final result. Graphic design often refers to both the process (designing) by which the
communication is created and the products (designs) which are generated.
Common uses of graphic design include identity (logos and branding), publications (magazines,
newspapers, and books), advertisements and product packaging. For example, a product package
might include a logo or other artwork, organized text and pure design elements such as shapes
and color which unify the piece. Composition is one of the most important features of graphic
design, especially when using pre-existing materials or diverse elements
While Graphic Design as a discipline has a relatively recent history, with the term "graphic
design" first coined by William Addison Dwiggins in 1922,[2] graphic design-like activities span
the history of humankind: from the caves of Lascaux, to Rome's Trajan's Column to the
illuminated manuscripts of the Middle Ages, to the dazzling neons of Ginza. In both this lengthy
history and in the relatively recent explosion of visual communication in the 20th and 21st
centuries, there is sometimes a blurring distinction and over-lapping of advertising art, graphic
design and fine art. After all, they share many of the same elements, theories, principles,
practices and languages, and sometimes the same benefactor or client. In advertising art the
ultimate objective is the sale of goods and services. In graphic design, "the essence is to give
order to information, form to ideas, expression and feeling to artifacts that document human
experience.
3) Tools
The mind may be the most important graphic design tool. Aside from technology, graphic design
requires judgment and creativity. Critical, observational, quantitative and analytic thinking are
required for design layouts and rendering. If the executor is merely following a solution (e.g.
sketch, script or instructions) provided by another designer (such as an art director), then the
executor is not usually considered the designer.
The method of presentation (e.g. arrangement, style, medium) may be equally important to the
design. The layout is produced using external traditional or digital image editing tools. The
appropriate development and presentation tools can substantially change how an audience
perceives a project.
In the mid 1980s, the arrival of desktop publishing and graphic art software applications
introduced a generation of designers to computer image manipulation and creation that had
previously been manually executed. Computer graphic design enabled designers to instantly see
the effects of layout or typographic changes, and to simulate the effects of traditional media
without requiring a lot of space. However, traditional tools such as pencils or markers are useful
even when computers are used for finalization; a designer or art director may hand sketch
numerous concepts as part of the creative process. Some of these sketches may even be shown to
a client for early stage approval, before the designer develops the idea further using a computer
and graphic design software tools.
Computers are considered an indispensable tool in the graphic design industry. Computers and
software applications are generally seen by creative professionals as more effective production
tools than traditional methods. However, some designers continue to use manual and traditional
tools for production, such as Milton Glaser.
New ideas can come by way of experimenting with tools and methods. Some designers explore
ideas using pencil and paper.[12] Others use many different mark-making tools and resources
from computers to sculpture as a means of inspiring creativity. One of the key features of graphic
design is that it makes a tool out of appropriate image selection in order to possibly convey
meaning.
There is some debate whether computers enhance the creative process of graphic design.[14]
Rapid production from the computer allows many designers to explore multiple ideas quickly
with more detail than what could be achieved by traditional hand-rendering or paste-up on paper,
moving the designer through the creative process more quickly.[15] However, being faced with
limitless choices does not help isolate the best design solution and can lead to endless iterations
with no clear design outcome.
A graphic designer may use sketches to explore multiple or complex ideas quickly[16] without the
distractions and complications of software.[citation needed] Hand-rendered comps are often used to
get approval for an idea execution before a designer invests time to produce finished visuals on a
computer or in paste-up. The same thumbnail sketches or rough drafts on paper may be used to
rapidly refine and produce the idea on the computer in a hybrid process. This hybrid process is
especially useful in logo design[17] where a software learning curve may detract from a creative
thought process. The traditional-design/computer-production hybrid process may be used for
freeing one's creativity in page layout or image development as well.[citation needed] In the early days
of computer publishing, many "traditional" graphic designers relied on computer-savvy
production artists to produce their ideas from sketches, without needing to learn the computer
skills themselves. However, this practice has been increasingly less common since the advent of
desktop publishing over 30 years ago. The use of computers and graphics software is now taught
in most graphic design courses. As well, many graphic designers take advantage of a multitude
of online tools and resources including color pickers, fonts, clipart, tutorials and more.[18]

4. Skills
A graphic design project may involve the stylization and presentation of existing text and either
preexisting imagery or images developed by the graphic designer. For example, a newspaper
story begins with the journalists and photojournalists and then becomes the graphic designer's
job to organize the page into a reasonable layout and determine if any other graphic elements
should be required. In a magazine article or advertisement, often the graphic designer or art
director will commission photographers or illustrators to create original pieces just to be
incorporated into the design layout. Or the designer may utilize stock imagery or photography.
Contemporary design practice has been extended to the modern computer, for example in the use
of WYSIWYG user interfaces, often referred to as interactive design, or multimedia design.
Visual arts
Before any graphic elements may be applied to a design, the graphic elements must be originated
by means of visual art skills. These graphics are often (but not always) developed by a graphic
designer. Visual arts include works which are primarily visual in nature using anything from
traditional media, to photography or computer generated art. Graphic design principles may be
applied to each graphic art element individually as well as to the final composition.
Typography
Typography is the art, craft and techniques of type design, modifying type glyphs, and arranging
type. Type glyphs (characters) are created and modified using a variety of illustration techniques.
The arrangement of type is the selection of typefaces, point size, tracking (the space between all
characters used), kerning (the space between two specific characters), and leading (line spacing).
Typography is performed by typesetters, compositors, typographers, graphic artists, art directors,
and clerical workers. Until the Digital Age, typography was a specialized occupation.
Digitization opened up typography to new generations of visual designers and lay users.
Page layout
The page layout aspect of graphic design deals with the arrangement of elements (content) on a
page, such as image placement, and text layout and style. Beginning from early illuminated
pages in hand-copied books of the Middle Ages and proceeding down to intricate modern
magazine and catalogue layouts, structured page design has long been a consideration in printed
material. With print media, elements usually consist of type (text), images (pictures), and
occasionally place-holder graphics for elements that are not printed with ink such as die/laser
cutting, foil stamping or blind embossing.
Interface design
Since the advent of the World Wide Web and computer software development, many graphic
designers have become involved in interface design. This has included web design and software
design, when end user interactivity is a design consideration of the layout or interface.
Combining visual communication skills with the interactive communication skills of user
interaction and online branding, graphic designers often work with software developers and web
developers to create both the look and feel of a web site or software application and enhance the
interactive experience of the user or web site visitor. An important aspect of interface design is
icon design.
User experience design
Considers how a user interacts with and responds to an interface, service or product and adjusts it
accordingly.
Printmaking
Printmaking is the process of making artworks by printing on paper and other materials or
surfaces. Except in the case of monotyping, the process is capable of producing multiples of the
same piece, which is called a print. Each piece is not a copy but an original since it is not a
reproduction of another work of art and is technically known as an impression. Painting or
drawing, on the other hand, create a unique original piece of artwork. Prints are created from a
single original surface, known technically as a matrix. Common types of matrices include: plates
of metal, usually copper or zinc for engraving or etching; stone, used for lithography; blocks of
wood for woodcuts, linoleum for linocuts and fabric plates for screen-printing. But there are
many other kinds, discussed below. Works printed from a single plate create an edition, in
modern times usually each signed and numbered to form a limited edition. Prints may also be
published in book form, as artist's books. A single print could be the product of one or multiple
techniques.
5.Multimedia
Multimedia is media and content that uses a combination of different content forms. The term
can be used as a noun (a medium with multiple content forms) or as an adjective describing a
medium as having multiple content forms. The term is used in contrast to media which use only
rudimentary computer display such as text-only, or traditional forms of printed or hand-produced
material. Multimedia includes a combination of text, audio, still images, animation, video, or
interactivity content forms.
Multimedia is usually recorded and played, displayed or accessed by information content
processing devices, such as computerized and electronic devices, but can also be part of a live
performance. Multimedia (as an adjective) also describes electronic media devices used to store
and experience multimedia content. Multimedia is distinguished from mixed media in fine art; by
including audio, for example, it has a broader scope. The term "rich media" is synonymous for
interactive multimedia. Hypermedia can be considered one particular multimedia application.
Categorization of multimedia
Multimedia may be broadly divided into linear and non-linear categories. Linear active content
progresses often without any navigational control for the viewer such as a cinema presentation.
Non-linear uses interactivity to control progress as with a video game or self-paced computer
based training. Hypermedia is an example of non-linear content.
Multimedia presentations can be live or recorded. A recorded presentation may allow
interactivity via a navigation system. A live multimedia presentation may allow interactivity via
an interaction with the presenter or performer.
Major characteristics of multimedia
Multimedia presentations may be viewed by person on stage, projected, transmitted, or played
locally with a media player. A broadcast may be a live or recorded multimedia presentation.
Broadcasts and recordings can be either analog or digital electronic media technology. Digital
online multimedia may be downloaded or streamed. Streaming multimedia may be live or ondemand.
Multimedia games and simulations may be used in a physical environment with special effects,
with multiple users in an online network, or locally with an offline computer, game system, or
simulator.
The various formats of technological or digital multimedia may be intended to enhance the users'
experience, for example to make it easier and faster to convey information. Or in entertainment
or art, to transcend everyday experience.
Enhanced levels of interactivity are made possible by combining multiple forms of media content. Online
multimedia is increasingly becoming object-oriented and data-driven, enabling applications with
collaborative end-user innovation and personalization on multiple forms of content over time. Examples
of these range from multiple forms of content on Web sites like photo galleries with both images
(pictures) and title (text) user-updated, to simulations whose co-efficients, events, illustrations, animations
or videos are modifiable, allowing the multimedia "experience" to be altered without reprogramming. In
addition to seeing and hearing, Haptic technology enables virtual objects to be felt. Emerging technology
involving illusions of taste and smell may also enhance the multimedia experience.
Broadcasting is the distribution of audio and video content to a dispersed audience via any
audio visual medium. Receiving parties may include the general public or a relatively large
subset thereof. It has been used for purposes of private recreation, non-commercial exchange of
messages, experimentation, self-training, and emergency communication such as amateur (ham)
radio and amateur television (ATV) in addition to commercial purposes like popular radio or TV
stations with advertisements.
The term broadcast was first adopted by early radio engineers from the Midwestern United
States,[1] treating broadcast sowing as a metaphor for the dispersal inherent in omnidirectional
radio signals.Broadcasting is a very large and significant segment[quantify] of the mass media.
Originally all broadcasting was composed of analog signals using analog transmission
techniques and more recently broadcasters have switched to digital signals using digital
transmission.

Wireless
The world's technological capacity to receive information through one-way broadcast networks
more than quadrupled during the two decades from 1986 to 2007, from 432 exabytes of
(optimally compressed) information, to 1.9 zettabytes.[2] This is the information equivalent of 55
newspapers per person per day in 1986, and 175 newspapers per person per day by 2007
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.
Commercial uses
Much of the electronic old and new media used by commercial artists is multimedia. Exciting
presentations are used to grab and keep attention in advertising. Business to business, and
interoffice communications are often developed by creative services firms for advanced
multimedia presentations beyond simple slide shows to sell ideas or liven-up training.
Commercial multimedia developers may be hired to design for governmental services and
nonprofit services applications as well.
Entertainment and fine arts
In addition, multimedia is heavily used in the entertainment industry, especially to develop
special effects in movies and animations. Multimedia games are a popular pastime and are
software programs available either as CD-ROMs or online. Some video games also use
multimedia features. Multimedia applications that allow users to actively participate instead of
just sitting by as passive recipients of information are called Interactive Multimedia. In the Arts
there are multimedia artists, whose minds are able to blend techniques using different media that
in some way incorporates interaction with the viewer. One of the most relevant could be Peter
Greenaway who is melding Cinema with Opera and all sorts of digital media. Another approach
entails the creation of multimedia that can be displayed in a traditional fine arts arena, such as an
art gallery. Although multimedia display material may be volatile, the survivability of the
content is as strong as any traditional media. Digital recording material may be just as durable
and infinitely reproducible with perfect copies every time.
Education
In Education, multimedia is used to produce computer-based training courses (popularly called
CBTs) and reference books like encyclopedia and almanacs. A CBT lets the user go through a
series of presentations, text about a particular topic, and associated illustrations in various
information formats. Edutainment is an informal term used to describe combining education with
entertainment, especially multimedia entertainment.
Learning theory in the past decade has expanded dramatically because of the introduction of
multimedia. Several lines of research have evolved (e.g. Cognitive load, Multimedia learning,
and the list goes on). The possibilities for learning and instruction are nearly endless.
The idea of media convergence is also becoming a major factor in education, particularly higher
education. Defined as separate technologies such as voice (and telephony features), data (and
productivity applications) and video that now share resources and interact with each other,
synergistically creating new efficiencies, media convergence is rapidly changing the curriculum
in universities all over the world. Likewise, it is changing the availability, or lack thereof, of jobs
requiring this savvy technological skill.
The English education in middle school in China is well invested and assisted with various
equipments. In contrast, the original objective has not been achieved at the desired effect. The
government, schools, families, and students spend a lot of time working on improving scores, but
hardly gain practical skills. English education today has gone into the vicious circle. Educators
need to consider how to perfect the education system to improve students’ practical ability of
English. Therefore an efficient way should be used to make the class vivid. Multimedia teaching
will bring students into a class where they can interact with the teacher and the subject.
Multimedia teaching is more intuitive than old ways; teachers can simulate situations in real life.
In many circumstances teachers don’t have to be there, students will learn by themselves in the
class. More importantly, teachers will have more approaches to stimulating students’ passion of
learning
Journalism
Newspaper companies all over are also trying to embrace the new phenomenon by implementing
its practices in their work. While some have been slow to come around, other major newspapers
like The New York Times, USA Today and The Washington Post are setting the precedent for the
positioning of the newspaper industry in a globalized world.
News reporting is not limited to traditional media outlets. Freelance journalists can make use of
different new media to produce multimedia pieces for their news stories. It engages global
audiences and tells stories with technology, which develops new communication techniques for
both media producers and consumers. Common Language Project is an example of this type of
multimedia journalism production.
Multimedia reporters who are mobile (usually driving around a community with cameras, audio
and video recorders, and wifi-equipped laptop computers) are often referred to as Mojos, from
mobile journalist.
Engineering
Software engineers may use multimedia in Computer Simulations for anything from
entertainment to training such as military or industrial training. Multimedia for software
interfaces are often done as a collaboration between creative professionals and software
engineers.
Industry
In the Industrial sector, multimedia is used as a way to help present information to shareholders,
superiors and coworkers. Multimedia is also helpful for providing employee training, advertising
and selling products all over the world via virtually unlimited web-based technology
Mathematical and scientific research
In mathematical and scientific research, multimedia is mainly used for modeling and simulation.
For example, a scientist can look at a molecular model of a particular substance and manipulate
it to arrive at a new substance. Representative research can be found in journals such as the
Journal of Multimedia.
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.
Document imaging
Document imaging is a technique that takes hard copy of an image/document and converts it into
a digital format (for example, scanners).
Disabilities
Ability Media allows those with disabilities to gain qualifications in the multimedia field so they
can pursue careers that give them access to a wide array of powerful communication forms.
Miscellaneous
In Europe, the reference organisation for Multimedia industry is the European Multimedia
Associations Convention (EMMAC)
