2. USER GENARATED CONTENT
This is the publication of content by the gen-
eral public not by paid professional UGC is the
term used to describe any form of content
such as video, blogs discussion form posts,
digital images, audio files, and other forms of
media that was created by consumers or end-
users of an online system or service and is
publically available to others consumers and
end-users. User-generated content is also
called consumer generated media , this is
shown on sites such as Facebook ,twitter,
tumbler and MySpace. This can be used as a
great way to keep in touch with people but it
also can be dangerous for some children using
FILM TRAILERS
a short promotional film composed of clips showing
highlights of a movie due for release in the near fu-
ture. This is good to let people see what the general
idea of a film is before they go and watch it ,it is good
because it grabs the interest of the audience and
makes them want to go and watch it

3. E-LEARNING
E-learning includes all forms of electronically supported
learning and teaching, including Edtech. The information
and communication systems, whether networked learning
or not, serve as specific media to implement the learning
process. The term will still most likely be utilized to refer-
ence out-of-classroom and in-classroom educational expe-
riences via technology, even as advances continue in regard
to devices and curriculum.
PLATFORMS
A platform is a crucial element in software development. A
platform might be simply defined as a place to launch software.
The platform provider offers the software developer an under-
taking that logic code will run consistently as long as the plat-
form is running on top of other platforms. Logic code includes
byte code, source code, and machine code. It actually means
execution of the program is not restricted by the type of oper-
ating system provided. It has mostly replaced the
machine-independent languages

4. KIOSK
In information technology, a kiosk is a small physical
structure (often including a computer and a display
screen) that displays information for people walking by.
Kiosks are common near the entrances of shopping malls
in North America where they provide shoppers with di-
rections. Kiosks are also used at trade shows and profes-
sional conferences. The word is of Turkish and earlier
Persian origin, where it meant an outdoor pavilion or a
portico. The kiosks best known to travellers are those that
display show and movie posters on the streets of Paris.
WWW (WORLD WIDE WEB )
A technical definition of the World Wide Web is: all the re-
sources and users on the Internet that are using the Hyper-
text Transfer Protocol (HTTP).A broader definition comes
from the organization that Web inventor Tim Berners-Lee
helped found, the World Wide Web Consortium the world
wide web is very useful for many things mainly getting in-
formation that may be hard to find in books in a li-
brary ,people often us it to keep in touch with other people
using social networking sites such as twitter or Facebook

5. MOBILE DEVICES
A mobile device (also known as a handheld device,
handheld computer or simply handheld) is a small, hand-
held computing device, typically having a display screen
with touch input and/or a miniature keyboard . Apple,
HTC, Samsung, LG, Research in Motion (RIM) and
Motorola are just a few examples of the many manufactur-
ers that produce these types of devices. Within these devic-
es you can download apps witch are little pieces of down-
loadable software that can do specific jobs they can be a
game, ringtone downloader or a add on to something on
your device such as a app for your camera that you can edit
the photos you take on the device.

MEDIA PLAYER / STREAMING METHODS
Media player is a term typically used to describe computer software for
playing back multimedia files. While many media players can play both
audio and video, others focus only on one media type or the other.
Such players are known as either audio players or video players and
often have a user interface tailored for the specific media type.
COMPRESSION
In computer science and information theory, data compression, source coding,
[1] or bit-rate reduction involves encoding information using fewer bits than
the original representation. Compression can be either be lossy or lossless.
Lossless compression reduces bits by identifying and eliminating statistical re-
dundancy. No information is lost in lossless compression. Lossy compression
reduces bits by identifying marginally important information and removing it.
The process of reducing the size of a data file is popularly referred to as data
compression, although its formal name is source coding (coding done at the
source of the data, before it is stored or transmitted).
7. DIGITAL FILE FORMATS,
file formats are orderly sequences of data used to encode
digital information for storage or exchange. They are like written languages, with their own
peculiar rules or grammars. Although they are structured in different ways, digital media files
generally begin with an introductory 'header' section followed by a 'body', which contains most
of the data. In time-based media files this structure is often described as ‘wrapper' format (the
envelope that holds various elements together such as video, audio and related metadata) and
‘codec' which is the language used to encode the actual media content.
TRANSFER RATE
The data transfer rate is commonly used to measure how fast data is trans-
ferred from one location to another. For example, a hard drive may have a
maximum data transfer rate of 480 Mbps, while your ISP may offer an In-
ternet connection with a maximum data transfer rate of only 1.5 Mbps.
Data transfer rates are typically measured in bits per second (bps) as op-
posed to bytes per second, which can be understandably confusing. Because
there are eight bits in a byte, a sustained data transfer rate of 80 Mbps is
only transferring 10MB per second. While this is confusing for consumers,
Internet service providers must enjoy measuring data transfer rates in bps
since it makes their Internet access speeds sound 8x faster than they really
are.
8. FILE SIZE
Jump to: navigation, search
File size measures the size of a computer file. Typically it is measured in bytes with a
prefix. The actual amount of disk space consumed by the file depends on the file sys-
tem The maximum file size a file system supports depends on the number of bits re-
served to store size information and the total size of the file system. For example,
with FAT32, the size of one file cannot be equal or larger than 4 GiB. Some common
file size units are
1 byte = 8 bits
1 KiB = 1,024 bytes
1 MiB = 1,048,576 bytes[1]
DIGITAL RIGHTS MANAGEMENT SYSTEMS.
digital rights management, a system for protecting the copyrights of data circulat-
ed via the Internet or other digital media by enabling secure distribution and/or
disabling illegal distribution of the data. Typically, a DRM system protects intellec-
tual property by either encrypting the data so that it can only be accessed by au-
thorized users or marking the content with a digital watermark or similar method
so that the content can not be
freely distributed
