MULTIMEDIA PRESENTATION
AND WEB TECHNOLOGIES
MULTIMEDIA PRESENTATION
is a stand alone presentation that includes information
presented with slides, video, or digital representations and
includes sound which might be a narrative, music or sound
effects.
WEB TECHNOLOGIES
Web technology refers to the means by which computers communicate
with each other using markup languages and multimedia software
packages. This gives us a way to interact with hosted information, such as
websites. Web technology involves the use of Hypertext Markup Language
(HTML) and Cascading Style Sheets (CSS).
Over all it is composed of Computer-based, interactive
applications having multiple media elements, including text,
graphics, animations, video, and sound. It also refers to
both the hardware and software used to create and run
such systems and with the use of web of any things that
needs internet or inter action with the web.
TYPES OF MULTIMEDIA
PRESENTATION
TEXT
Text is the most common multimedia element. The text expresses the information
the developer is trying to get across to their viewers. Even though pictures grab the
viewers’ attention, the text is a good idea to include, as well, just in case the picture
does not load
PICTURE OR IMAGE
An image catches the viewers’ attention much more quickly than just plain, old
text. Almost every multimedia application contains images. The most common
images are JPEGS and PNGs. Also, Photoshop and Paint.NET create high tech
visual effects which are common with images
AUDIO
Most of the time, audio files are deployed using plug-in media
players. A few audio formats include RealAudio, MIDI, Wave, WMA,
and MP3. The developer will compress the format to shorten the
time. Before the file is downloaded, one can stream the audio.
VIDEOS
he web is the most common place where videos are seen concerning multimedia
elements. A few digital video formats are Flash, MPEG, AVI, WMV, and
QuickTime. Streaming digital videos can increase the speed of the playback.
Developers use videos to hold on to the viewers’ attention
ANIMATION
Animation draws in the younger crowd. adobe flash is the most
common tool for creating these animations. Animations are the
most creative and fun multimedia element.
TYPES OF WEB TECHNOLOGIES
BROWSERS
Browsers are the interpreters of the web. They request information and
then when they receive it, they show us on the page in a format we can
see and understand.
HTML
is a markup language. It provides the structure of a website so that
web browsers know what to show.
CSS
is a Cascading Style Sheet. CSS let’s web designers change
colors, fonts, animations, and transitions on the web. They
make the web look good.
PROGRAMMING LANGUAGES
Programming languages are ways to communicate to computers and tell them
what to do. There are many different programming languages just like there are
many different lingual languages (English, Spanish, French, Chinese, etc). One
is not better than the other. Developers typically are just proficient at a couple so
they promote those more than others. Below are just some of the languages and
links to their homepages
FRAMEWORKS
Frameworks are built to make building and working with programming
languages easier. Frameworks typically take all the difficult, repetitive tasks
in setting up a new web application and either does them for you or make
them very easy for you to do.
LIBRARIES
Libraries are groupings of code snippets to enable a large amount of
functionality without having to write it all by yourself. Libraries typically also
go through the trouble to make sure the code is efficient and works well
across browsers and devices (not always the case, but typically they do).
DATABASES
Databases are where all your data is stored. It’s like a bunch of filing
cabinets with folders filled with files. Databases come mainly in two
flavors: SQL and NoSQL. SQL provides more structure which helps with
making sure all the data is correct and validated. NoSQL provides a lot of
flexibility for building and maintaining applications.
FRONT-END
The front-end is comprised of HTML, CSS, and Javascript. This is how
and where the website is shown to users.
BACK-END
The back-end is comprised of your server and database. It’s the place
where functions, methods, and data manipulation happens that you don’t
want the clients to see.
PROTOCOLS
Protocols are standardized instructions for how to pass information back
and forth between computers and devices.
API
An API is an application programming interface. It is created by the
developer of an application to allow other developers to use some of the
application's functionality without sharing code. Developers expose “end
points” which are like inputs and outputs of the application. Using an API
can control access with API keys. Examples of good API’s are those
created by Facebook, Twitter, and Google for their web services.
DATA FORMATS
Data formats are the structure of how data is stored.
KINDS OF MULTIMEDIA
PRESENTATION AND WEB TECH
ANIMATION AND THE WEB
Like other types of multimedia, animation poses some specific
accessibility issues for
Web users with sight or hearing disabilities or specialized software.
If you include
animation in your site, you should provide alternative content to
maximize accessibility
for all users. Images in Web pages should always include the alt
attribute to specify
descriptive alternative text. Short animations that can be described
in a few words can
also use the alt attribute this way. For longer animations, however,
you must take
additional steps to ensure accessibility
AUDIO AND THE WEB
Audio differs from other Web content in that it does not rely on the
display for the user to
experience the media. The constraints of monitor size, operating
system and color bit
depth do not apply.
Audio can now be delivered in two distinct ways. The user can
download the entire audio
file and then begin the playback process, or the audio file can be
delivered in streaming
format.
The playback quality of any sound recording is dependent on the
process and formats
used to create the digital file, and the quality of the output devices
on the users' systems.
VIDEO AND THE WEB
Video for the Web is another evolving technology that will
eventually become as common
as static images. However, the video currently available to users via
dial-up connections
is often considered low quality
